Best CMMS for Oil and Gas 2026

How We Evaluated

This guide is independent editorial analysis based on publicly available product documentation, verified customer reviews across G2 and Capterra, hands-on product demonstrations, and conversations with reliability engineers, mechanical integrity specialists, and operations leaders across upstream, midstream, and downstream operations. Reliable Magazine does not sell CMMS or EAM software and has no commercial interest in routing buyers toward any particular platform. Reliable does not accept payment for rankings. Vendors may sponsor enhanced listings with additional detail, but editorial rankings are independent. Read our editorial policy.

We evaluated each platform across six criteria that matter most for oil and gas CMMS decisions:

• Process Safety Management compliance – native support for OSHA 1910.119 elements including Mechanical Integrity, Management of Change, and incident documentation
• Mechanical Integrity programs – API standard compliance (510, 570, 580, 581, 653), risk-based inspection workflows, and corrosion management
• OSIsoft PI System integration – quality of native or middleware integration with the dominant oil and gas historian
• Mobile and offline capability – usability for technicians at remote wellsites, pipeline stations, offshore platforms, and refinery field operations
• ERP integration – handshake quality with SAP S/4HANA, Oracle EBS, and other ERPs common in oil and gas operations
• Track record at scale – proven deployments across oil and gas majors, supermajors, and complex independent operators

Why Oil and Gas CMMS Is Different

Oil and gas CMMS selection differs fundamentally from general CMMS evaluation. Four characteristics drive the differences. First, Process Safety Management compliance is non-negotiable. OSHA 1910.119 governs facilities handling highly hazardous chemicals – which includes most oil and gas processing operations – and requires fourteen specific elements including Mechanical Integrity, Management of Change, incident investigation, and contractor management. PSM failures result in catastrophic incidents, regulatory shutdowns, and personal liability for operations leaders. CMMS that supports PSM workflows out of the box meaningfully reduces compliance overhead. CMMS that requires extensive configuration to approximate PSM workflows creates compliance risk that is difficult to discover until an audit or incident.

Second, Mechanical Integrity programs follow API standards that horizontal CMMS rarely supports natively. API 510 governs pressure vessel inspection. API 570 governs piping inspection. API 580 and 581 define risk-based inspection methodology. API 653 governs above-ground storage tanks. Each standard specifies inspection intervals, methodology, qualification requirements, and documentation that must be evident in CMMS records during regulatory audits. Platforms with pre-configured API workflows save substantial implementation time and reduce audit findings. Platforms without them require expensive custom development that frequently produces gaps that surface during incidents.

Third, oil and gas operations run in environments that punish weak mobile software. Remote wellsites have intermittent cellular connectivity. Offshore platforms operate beyond cellular range. Pipeline pigging stations sit at unmanned locations across hundreds of miles. Refinery field operations require intrinsically safe device certification. CMMS platforms that require continuous connectivity for work order execution fail in these environments. Mobile usability with full offline capability is operationally critical, not optional.

Fourth, oil and gas operations depend on industrial historians at a level uncommon outside the industry. OSIsoft PI System (now AVEVA PI) is essentially universal across upstream, midstream, and downstream. Process data – temperatures, pressures, flows, vibration, levels – flows continuously from DCS systems through PI to operations and reliability teams. CMMS that integrates cleanly with PI enables condition-based maintenance triggered by actual equipment conditions. CMMS that doesn’t integrate with PI either operates in isolation from process reality or requires fragile custom integrations that produce data quality problems.

The 7 Best CMMS Platforms for Oil and Gas in 2026

1. IBM Maximo Application Suite – Best for Oil and Gas Overall

IBM Maximo leads the oil and gas CMMS category through depth, scale, and track record that no competitor fully matches. The Maximo for Oil and Gas industry solution includes pre-configured PSM workflows, Mechanical Integrity modules with full API standard compliance frameworks (510, 570, 580, 581, 653), risk-based inspection support, and integration with OSIsoft PI through the Maximo PI Connector. Operations can deploy Maximo with PSM and MI capabilities operational within weeks rather than the months required to configure horizontal CMMS for the same workflows.

The platform’s track record at scale is the strongest in the industry. ExxonMobil, Shell, Chevron, BP, Saudi Aramco, ADNOC, Petrobras, and most other oil and gas majors run Maximo as their primary asset management platform. The deployment depth means Maximo’s oil and gas-specific functionality has been refined through decades of real production use rather than designed for theoretical scenarios. Documentation, training resources, implementation partner ecosystem, and reference customer access are all stronger for oil and gas than any alternative platform.

The trade-off is implementation complexity and total cost of ownership. Maximo deployments at oil and gas scale typically run six to eighteen months with implementation costs ranging from mid six figures to seven figures or more. The platform requires dedicated administration resources and integration overhead that smaller operators cannot easily absorb. For oil and gas majors and large independents, the depth justifies the investment. For smaller operators and oilfield service companies, mid-market alternatives generally deliver better value.

Best for: Oil and gas majors, supermajors, large national oil companies, and complex independent operators with multi-asset operations and significant PSM exposure.

Pricing: Custom enterprise pricing. Per-user costs typically run $150 to $300 per user per month for full Maximo Application Suite deployments. Implementation costs range from mid six figures to seven figures or more.

2. SAP S/4HANA Asset Management – Best for SAP-Standardized Operators

SAP S/4HANA Asset Management (the successor to SAP Plant Maintenance, or PM) is the strongest oil and gas CMMS for operators standardized on SAP across ERP, supply chain, and finance. The native integration with SAP S/4HANA modules eliminates middleware overhead that other platforms require for ERP handshakes. Maintenance work orders flow directly from financial controls through procurement to execution and back into financial reporting without integration friction. For operators where SAP is the corporate standard, this integration depth typically outweighs Maximo’s oil and gas-specific feature advantages.

SAP’s oil and gas industry framework includes PSM workflow support, MI capabilities through the Asset Management module, and integration paths to PI System through SAP MII (Manufacturing Integration and Intelligence) or direct connectors. The depth of oil and gas-specific configuration is meaningful though generally less out-of-the-box than Maximo’s industry solution. SAP’s strength is in operators where the integration story matters more than industry-specific feature depth.

Major oil and gas SAP deployments include Aramco, ConocoPhillips, Equinor, Eni, and many large independents. The track record is genuine and the platform handles oil and gas operations at scale. The trade-off is implementation complexity comparable to Maximo, with longer deployment timelines for operators not already running SAP.

Best for: Oil and gas operators standardized on SAP S/4HANA across ERP and supply chain, where native integration outweighs industry-specific feature depth.

Pricing: Custom enterprise pricing as part of SAP S/4HANA licensing. Asset Management is typically licensed alongside Plant Maintenance and Supply Chain modules. Implementation runs in the seven-figure range for major deployments.

3. AVEVA Asset Performance Management – Best for Downstream and Process Operations

AVEVA APM is the strongest pick for downstream refining, petrochemicals, and process operations standardized on AVEVA control infrastructure. The platform combines maintenance management with asset performance analytics and integrates natively with AVEVA System Platform (formerly Wonderware) and AVEVA PI System. The depth of process plant integration – from DCS data through historian through APM – is unmatched in the oil and gas software market for operators in the AVEVA ecosystem.

The platform supports risk-based inspection workflows, mechanical integrity programs, and reliability-centered maintenance methodology. The APM analytics layer adds capabilities beyond traditional CMMS: predictive maintenance models, asset performance dashboards, and anomaly detection from process data. For downstream operators where the boundary between maintenance and process operations is porous – and where process data drives maintenance decisions – AVEVA’s integrated approach is operationally compelling.

The trade-off is fit outside the AVEVA ecosystem. Operators standardized on Honeywell DCS, Emerson DeltaV, or other non-AVEVA control infrastructure find the integration story less compelling. AVEVA’s strength is concentrated in refineries and petrochemical operations rather than upstream production, where the platform is less commonly deployed at scale.

Best for: Downstream refineries, petrochemical operations, and process plants standardized on AVEVA System Platform and AVEVA PI System.

Pricing: Custom enterprise pricing. Typically licensed as part of broader AVEVA portfolio agreements that include System Platform and PI System.

4. Infor EAM – Best Mid-Market Choice for Oil and Gas

Infor EAM is the strongest mid-market option for oil and gas operators that need genuine industry capability without Tier 1 enterprise complexity. The platform includes oil and gas-specific configurations covering PSM workflow support, mechanical integrity programs, API standard compliance, and operations across upstream and midstream. Infor’s oil and gas references include Marathon Oil, Hess, and several mid-size independents that found Maximo and SAP over-scoped for their operational scale.

Implementation timelines run faster than Maximo or SAP – typical deployments complete in three to nine months versus six to eighteen for Tier 1 platforms. Per-user costs are meaningfully lower while feature depth remains adequate for operations under approximately 10,000 assets per asset register. Mobile usability is solid, and the platform supports OSIsoft PI integration through standard connectors.

The trade-off compared to Tier 1 platforms is in the largest deployments. Operators with 50,000+ assets, complex multi-country operations, or strict requirements for vendor financial stability sometimes find Infor’s scale less reassuring than IBM or SAP. For mid-size operators in the 1,000 to 25,000 asset range, Infor often delivers the best balance of capability, cost, and deployment speed.

Best for: Mid-market upstream and midstream operators between 1,000 and 25,000 assets, where deployment speed and cost matter alongside oil and gas industry capability.

Pricing: Custom enterprise pricing. Per-user costs typically run $75 to $150 per user per month. Implementation in the low to mid six figures for typical mid-market deployments.

5. Bentley AssetWise – Best for Pipeline and Linear Asset Management

Bentley AssetWise occupies a unique position in the oil and gas CMMS market. The platform is purpose-built for linear asset management – pipelines, transmission systems, and other geographically distributed infrastructure – where vertical asset CMMS platforms struggle to model the operational reality. Pipelines have unique characteristics that don’t fit traditional asset hierarchy models: assets are continuous rather than discrete, location is defined by milepost rather than facility, and integrity management spans hundreds of miles of variable terrain and conditions.

For midstream pipeline operators – Enbridge, TC Energy, Kinder Morgan, Williams, Plains All American – Bentley AssetWise handles the operational realities that general CMMS platforms cannot. The platform integrates pipeline integrity management, regulatory compliance reporting (PHMSA in the U.S., CER in Canada), inline inspection results, cathodic protection, and right-of-way management in ways that Maximo or SAP can approximate through configuration but not match natively.

The trade-off is fit outside pipeline operations. AssetWise serves vertical assets – wellsites, processing facilities, refineries — less well than horizontal asset platforms. Operators with mixed pipeline and vertical asset operations sometimes deploy AssetWise for pipeline assets alongside a different platform for facility maintenance, which creates integration complexity but matches operational reality better than forcing one platform to handle both.

Best for: Pipeline operators, transmission and distribution operations, and other midstream operations where linear asset management is the dominant operational requirement.

Pricing: Custom enterprise pricing. Implementation complexity varies based on pipeline mileage and integration requirements with inline inspection vendors.

6. eMaint – Best for Smaller Operators and Service Companies

eMaint serves a specific position in the oil and gas market that the Tier 1 platforms cannot reach economically. Smaller upstream operators with under 5,000 assets, oilfield service companies, well service contractors, and equipment rental companies need audit-ready compliance documentation without the implementation overhead of Maximo or SAP. eMaint provides PSM workflow support, custom inspection forms that can be configured for API standard compliance, and the Fluke ecosystem integration that gives compliance-friendly access to condition monitoring data.

The platform handles standard CMMS workflows – work orders, PM scheduling, parts inventory, asset management — alongside oil and gas-specific configurations. Implementation typically runs four to twelve weeks rather than months, and per-user pricing is meaningfully more accessible for operators outside the major or large independent tier. The mobile app handles offline work order completion adequately for most upstream service company use cases.

The trade-off compared to Tier 1 platforms is in the depth of oil and gas-specific functionality. eMaint’s API standard support comes through configuration rather than native modules. Risk-based inspection workflows are possible but require more setup. For operators with significant PSM exposure or large asset bases, Tier 1 platforms remain the safer choice. For smaller operators and service companies, eMaint hits a balance between industry capability and operational accessibility.

Best for: Smaller upstream operators under 5,000 assets, oilfield service companies, well service contractors, and equipment rental operators needing oil and gas capability without Tier 1 complexity.

Pricing: Custom enterprise pricing. Per-user costs typically start around $33 per user per month for the Team tier with Professional and Enterprise tiers above.

7. MaintainX – Best for Field Execution at Service Companies

MaintainX rounds out the lineup for upstream service companies and smaller midstream operators where mobile field execution is the primary operational priority. The platform’s mobile app is the strongest in the broader CMMS market for usability in challenging environments – clean interface, real-time messaging within work orders, photo capture, offline capability, and rapid technician adoption. For operations where pumpers, lease operators, or pipeline technicians complete work orders at remote sites with intermittent connectivity, MaintainX often outperforms heavier platforms on the variable that determines whether the CMMS produces useful data.

The Premium tier supports the asset hierarchy, PM scheduling, and parts inventory needed for serious oil and gas operations. Custom inspection forms can approximate PSM and MI workflows for operations without strict regulatory exposure. The platform integrates with most major IIoT platforms and ERPs through open APIs, which suits service companies that integrate their CMMS with customer systems.

The trade-off is in oil and gas-specific functionality depth. MaintainX does not include native PSM frameworks, API standard support, or mechanical integrity workflows. For operations subject to OSHA 1910.119 with significant compliance exposure, the configuration overhead to approximate these workflows is substantial. For service companies, well service operators, and smaller midstream operators where field execution speed matters more than regulatory framework depth, MaintainX often delivers better operational value than heavier platforms.

Best for: Upstream service companies, well service contractors, pumping companies, and smaller midstream operators where mobile field execution speed is the operational priority.

Pricing: Free (Basic), $20/user/month (Essential), $65/user/month (Premium), with custom Enterprise pricing.

Oil and Gas CMMS Comparison Table

Choosing by Segment: Upstream, Midstream, Downstream

Oil and gas CMMS selection differs meaningfully across the three industry segments. Each has distinct operational realities that change the platform fit.

Upstream Operations

Upstream operations span exploration, drilling, and production. Asset bases include drilling rigs, production wellsites, gathering systems, surface facilities, and remote infrastructure across geographically dispersed lease positions. CMMS requirements emphasize mobile and offline capability for remote field operations, integration with production data systems, well service workflow support, and PSM compliance for processing facilities. Major upstream operators (ExxonMobil, Shell, Chevron, EOG, Pioneer) typically run Maximo or SAP. Mid-market operators run Infor EAM or Maximo SaaS. Service companies and smaller operators often deploy MaintainX or eMaint for the mobile field execution advantage.

Midstream Operations

Midstream covers gathering, transmission, storage, and distribution between production and downstream processing. The defining characteristic is linear asset management at scale – pipelines spanning hundreds or thousands of miles, transmission systems with regulatory compliance requirements (PHMSA in the U.S.), and storage facilities with their own integrity management programs. Bentley AssetWise leads pipeline-specific deployments. Maximo and SAP serve large midstream operators with mixed asset portfolios. Infor EAM serves mid-market midstream operators. Pipeline integrity management workflows – inline inspection (smart pigging), cathodic protection, integrity assessment — are operationally critical and platform-specific.

Downstream Operations

Downstream covers refining, petrochemicals, and product distribution. Operations are characterized by complex process plants with thousands of assets per facility, continuous operations, severe regulatory exposure under PSM and EPA RMP, and dependence on industrial historians (PI System, AspenTech IP.21) for process data. AVEVA APM dominates AVEVA-standardized refineries. Maximo serves refineries with mixed control infrastructure. SAP serves SAP-standardized downstream operators. The boundary between APM and traditional CMMS is more porous in downstream than in other segments because process data drives maintenance decisions in ways that are less common upstream or midstream.

How to Choose the Right Oil and Gas CMMS

Beyond segment fit, four questions determine the right platform for a specific operation.

1. What is your PSM exposure?

Operations subject to OSHA 1910.119 with significant PSM compliance burden should prioritize platforms with native PSM frameworks – IBM Maximo, SAP S/4HANA, AVEVA APM, and Infor EAM all qualify. Operations with limited PSM exposure (some upstream production, oilfield services, equipment rental) have more flexibility and can use eMaint or MaintainX with configured workflows. The PSM gap in horizontal CMMS platforms is real and consequential, but it is binding only for operations where regulatory exposure makes it operationally critical.

2. What is your ERP standardization?

Operators standardized on SAP S/4HANA across ERP, supply chain, and finance should evaluate SAP S/4HANA Asset Management as the default choice because the integration eliminates middleware overhead. Operators standardized on Oracle EBS or other ERPs should evaluate Maximo, Infor EAM, or other CMMS with proven integration to their ERP. Mixed-ERP operators should prioritize platforms with strong integration capabilities (Maximo, Infor EAM) over platforms tied to specific ERP standards.

3. What is your historian environment?

Operations standardized on OSIsoft PI System (most of the industry) should prioritize platforms with native or proven PI integration – AVEVA APM has the deepest native integration, Maximo has the proven PI Connector, SAP integrates through SAP MII. Operations using AspenTech IP.21 or other historians should evaluate integration paths during procurement rather than assume support. The historian integration is one of the most consequential CMMS selection factors and one of the most often underestimated during procurement.

4. What is your operational scale?

Major operators with 50,000+ assets and complex multi-country operations should evaluate Maximo and SAP as the default choices. Mid-market operators with 1,000 to 25,000 assets should evaluate Infor EAM, Maximo SaaS, or AVEVA APM depending on segment fit. Smaller operators with under 5,000 assets should evaluate eMaint, MaintainX, or scaled-down Infor EAM deployments. Trying to deploy enterprise platforms at smaller scale frequently produces overengineered implementations that consume budget without proportionate operational value.

The Honest Middle Ground

Oil and gas CMMS is a category where the wrong choice creates regulatory and safety risk rather than just operational inefficiency. A few honest assessments worth flagging.

Operators sometimes underbuy on PSM capability. Upstream production operations subject to PSM (anywhere processing exceeds threshold quantities of highly hazardous chemicals) sometimes deploy mid-market CMMS without validating PSM workflow support. The gap surfaces during PSM compliance audits or – more dangerously – during incidents. The right approach is honest validation of PSM workflow fit during procurement, not afterward.

Operators sometimes overbuy on enterprise complexity. Mid-market operators occasionally deploy Maximo or SAP because their parent company or major investor standardized on them, ending up with implementations that take eighteen months and produce capabilities the operation does not actually use. Right-sizing matters. Infor EAM, scaled Maximo SaaS, or AVEVA APM at the appropriate tier often deliver better value than full enterprise deployments at mid-market scale.

Pipeline operators sometimes force vertical asset platforms onto linear assets. Pipelines have operational characteristics that don’t fit traditional asset hierarchy models, and forcing them produces brittle implementations that fail to support pipeline integrity management properly. Bentley AssetWise exists for a reason. Pipeline operators that try to use Maximo or SAP for pipeline-specific workflows generally find the results unsatisfactory compared to dedicated pipeline platforms.

Service companies sometimes deploy operator platforms. Oilfield service companies and well service contractors are not the same operational profile as oil and gas operators. Operators own facilities and assets; service companies execute work at customer locations across many operators. CMMS platforms designed for operator workflows often poorly serve service company workflows. MaintainX, eMaint, and similar mid-market platforms generally fit service companies better than Tier 1 operator-focused platforms.

Frequently Asked Questions

What is the best CMMS for oil and gas in 2026?

IBM Maximo Application Suite leads the oil and gas CMMS category in 2026 with the deepest Process Safety Management and Mechanical Integrity workflows, pre-configured API standard compliance frameworks, and the broadest deployments across oil and gas majors. SAP S/4HANA Asset Management is the strongest choice for SAP-standardized operators. AVEVA APM serves downstream and process operations with AVEVA control infrastructure. Infor EAM is the strongest mid-market choice. Bentley AssetWise leads pipeline and linear asset management in midstream. eMaint and MaintainX serve smaller operators and oilfield service companies.

How is oil and gas CMMS different from general CMMS?

Oil and gas CMMS prioritizes Process Safety Management compliance under OSHA 1910.119, Mechanical Integrity programs driven by API standards (510, 570, 580, 581, 653), risk-based inspection workflows, and integration with process data historians like OSIsoft PI System. Operations also require mobile usability in poor connectivity environments for remote wellsites, pipeline stations, and offshore platforms. General CMMS platforms rarely include these capabilities natively.

What is Process Safety Management and how does CMMS support it?

Process Safety Management (PSM) is the OSHA 1910.119 regulation that governs facilities handling highly hazardous chemicals. PSM requires fourteen elements including Mechanical Integrity for critical equipment, Management of Change workflows, incident investigation, and contractor management. CMMS supports PSM by documenting equipment inspections, tracking MI work orders against API standards, capturing MOC approvals before equipment changes, maintaining incident records, and producing audit-ready compliance reports.

What is Mechanical Integrity and which CMMS platforms support it?

Mechanical Integrity (MI) is the PSM element governing inspection, testing, and repair of process equipment to prevent loss of containment. MI programs follow API standards: API 510 for pressure vessels, API 570 for piping, API 580 and 581 for risk-based inspection, API 653 for above-ground storage tanks. IBM Maximo Oil and Gas, SAP S/4HANA, and AVEVA APM all support these workflows natively. Infor EAM and Bentley AssetWise support them through configuration. General CMMS platforms generally require custom development for full MI workflow support.

How does oil and gas CMMS integrate with OSIsoft PI System?

OSIsoft PI System, now part of AVEVA, is the dominant industrial historian in oil and gas operations. Process data flows from PI to CMMS to trigger condition-based maintenance work orders when equipment parameters exceed thresholds. AVEVA APM has native PI integration since the platforms share corporate ownership. IBM Maximo integrates through PI Connector or direct API. SAP S/4HANA integrates through SAP MII or middleware.

How much does oil and gas CMMS software cost?

Tier 1 enterprise platforms (IBM Maximo, SAP S/4HANA, AVEVA APM) typically run $100 to $300 per user per month with implementation costs ranging from mid six figures to seven figures or more. Mid-market platforms (Infor EAM, Bentley AssetWise) run $75 to $150 per user per month with implementation in the low to mid six figures. Mid-tier general CMMS adapted for oil and gas (eMaint, MaintainX Premium) run $40 to $100 per user per month with faster implementation.

Should upstream and downstream operations use the same CMMS?

Major integrated operators typically standardize on one platform across upstream, midstream, and downstream — usually IBM Maximo or SAP S/4HANA — for enterprise consistency and shared asset master data. Independent operators in single segments often choose differently. Upstream operators frequently use Maximo, SAP, or Infor EAM. Midstream pipeline operators often use Bentley AssetWise. Downstream refineries often use AVEVA APM.
