The trailing six months in oil & gas software produced two parallel consolidation stories. On one track, the public oilfield-services majors kept buying their way to digital depth: SLB carved S&P Global Energy’s entire upstream software portfolio out of S&P Global, and Halliburton picked up Sekal’s drilling-autonomy platform from Sumitomo. On the other, private equity continued to build vertical software around the rest of the value chain: Banneker Partners platformed ResFrac in subsurface simulation, Blackstone-owned Enverus added Spatial Business Systems on the utility-engineering side, and Valor-backed Zeitview bought its way into methane detection through Insight M. Five deals worth highlighting from the period, with the OFS-major thread leading the article and the PE-platform thread following.
S&P Global Energy Upstream Software acquired by SLB (April 2026)
Category: Subsurface & petroleum engineering software
Type: Strategic
SLB agreed to acquire S&P Global Energy’s geoscience and petroleum engineering software portfolio, the largest in-window oil & gas software transaction by a wide margin. The portfolio includes Kingdom Software, Petra, Harmony Enterprise, Analytics Explorer, SubPUMP, PowerTools, FieldDIRECT, Piper, WellTest, and the Element Platform. Together, the products are widely used by U.S. onshore and unconventional operators for daily seismic interpretation, reservoir analysis, well-test diagnostics, artificial-lift design, and field surveillance workflows.
The wider S&P Global Energy customer base spans roughly 110,000 users across 4,000 client organizations in 113 countries. A typical workflow: a Permian-focused independent loads its 3D seismic into Kingdom for interpretation, runs production decline analysis in Harmony Enterprise, and uses SubPUMP to model the artificial-lift system on each producing well. The same data set will now feed into SLB’s Lumi platform and Tela agentic-AI framework under a parallel collaboration agreement that the parties signed alongside the carve-out.
The strategic logic for SLB is twofold. First, it rolls a meaningful share of the U.S. unconventional subsurface stack under one roof, alongside SLB’s existing Petrel, Techlog, and Eclipse platforms. Second, it gives SLB a near-term training corpus for AI-driven subsurface and engineering models that the company has been building on top of Lumi and Tela. S&P Global, on the other side, is sharpening its focus on data and a new AI-powered upstream platform called Titan, which is currently in beta. Terms were not disclosed. The transaction is expected to close in the second half of 2026 or early 2027.
Sekal acquired by Halliburton (April 2026)
Category: Drilling automation software
Type: Strategic
Halliburton acquired Sekal AS, the Norwegian drilling-autonomy software company, from Sumitomo Corporation. Sekal was founded in 2011 as a spin-off of NORCE and IRIS, the Norwegian research institutes, and Sumitomo took control of the business in 2019 to scale it globally.
Sekal’s flagship is DrillTronics, a real-time drilling autonomy platform that builds advanced models of subsurface conditions, wellbore fluid behavior, and pressure systems and uses those models to control directional drilling tools and rig hardware. To date, the platform has been deployed across more than 1,300 wells, and Halliburton claims customers using the combined Halliburton-plus-Sekal solution see up to a 25% reduction in well delivery times through automated tripping, dynamic parameter optimization, and precise well placement. A typical use case: an operator drilling a horizontal lateral in a tight-tolerance reservoir target hands real-time directional control over to the system, which keeps the bit inside the pay zone with less manual intervention from the rig floor.
The deal pairs DrillTronics with Halliburton’s LOGIX automation and remote operations stack, giving Halliburton a more complete autonomy story across the well-construction workflow. Read together with SLB’s S&P Global purchase, the message from the OFS majors is consistent: each is buying out independent software depth in the corners of the upstream stack where it had been thinnest. Halliburton, which runs at roughly $23B in annual revenue, has been steadily stitching software into a hardware-led services business through deals like Sensia (its joint venture with Rockwell Automation) and prior add-ons in completions and reservoir intelligence.
ResFrac receives platform investment from Banneker Partners (April 2026)
Category: Subsurface simulation & hydraulic fracture modeling
Type: PE Platform
Banneker Partners made a platform investment in ResFrac Corporation, the Palo Alto-based subsurface simulation software company. ResFrac was founded in 2018 by Mark McClure, a former University of Texas at Austin petroleum engineering professor and Stanford-trained geomechanics researcher, and Charles A. Kang. Altira Group led an earlier round in 2020.
ResFrac’s product is the only commercial platform that couples reservoir simulation with hydraulic fracture modeling inside a single integrated simulator, so engineers can model a well’s full life cycle from the moment rock is fractured through years of production. The concrete workflow: a completions engineer at a Permian or Marcellus operator builds a simulation that runs thousands of stage designs virtually, varying proppant loading, cluster spacing, and fluid system, before committing the capital to actually drill and frac the well. Customers range from midsize independents to supermajors and national oil companies, and the platform is increasingly pulled into enhanced geothermal projects where the same coupled physics governs heat extraction.
Banneker Partners is a San Francisco and Portland-based enterprise software investor focused on the lower middle market, with more than $2B in AUM and a portfolio of 22 platforms and 75 add-ons. Recent platform investments include Industrial Defender (OT and ICS cybersecurity for industrial operators) and Texada Software (asset management for equipment dealers and rental fleets). The thesis on ResFrac fits the pattern: a vertical software platform with deep technical moat, a global customer base, and an obvious AI roadmap.
Spatial Business Systems acquired by Enverus (March 2026)
Category: Utility design automation
Type: Add-on
Enverus, the Blackstone-owned energy data and analytics platform, acquired Spatial Business Systems from Peak Rock Capital. SBS was founded in 2002 and sells intelligent design automation tools to electric and gas utilities, telecom providers, and engineering firms. Its product line includes Automated Utility Design (AUD), the Substation Design Suite (SDS), BIM Substation Designer, and Automated Broadband Designer.
Utility engineering shops have historically lived in CAD, hand-drafting every substation, distribution feeder, and broadband network design. SBS automates the heavy parts of that drafting work: equipment placement, clearance checks, and bill-of-materials generation in line with utility design standards. The company reports cycle-time reductions of up to 90% versus traditional CAD workflows, and its customer base spans North America, Europe, and Australia.
The deal connects two adjacent layers of the utility capital cycle. Enverus already gives utility planners and developers the market intelligence and capital-planning tools to figure out what to build and when. SBS adds the engineering-execution layer that turns those plans into work packages and stamped designs. The macro thesis is the roughly $1T of U.S. utility capex needed through 2029 to modernize aging infrastructure and absorb data-center, electrification, and grid-resilience load. The deal is the first major Enverus add-on since Blackstone bought Enverus from Hellman & Friedman and Genstar Capital in August 2025, and it signals the direction of platform expansion under new ownership: lean further into the utility customer base alongside the company’s traditional upstream and midstream data businesses. The transaction is expected to close in the second quarter of 2026.
As a reminder, two of the partners at ScaleView previously started a mineral rights software business called MineralSoft and sold it to Enverus in 2018 (and worked at Enverus for a few years after that).
Insight M acquired by Zeitview (February 2026)
Category: Methane detection & emissions intelligence
Type: Add-on
Zeitview, the AI-driven visual asset intelligence company, acquired Insight M, the aircraft-based methane leak-detection specialist. The deal marks Zeitview’s entry into oil and gas after spending the prior decade inspecting wind turbines, solar farms, telecom towers, and other infrastructure. Insight M’s customers include Occidental Petroleum, BP, and Targa.
Insight M flies fixed-wing aircraft equipped with proprietary methane sensors over upstream and midstream oil and gas infrastructure, then runs the resulting imagery and gas-concentration data through analytics that pinpoint individual leaks and rank them by repair priority and economic value. Over the past decade, the company says it has helped operators preserve roughly $900M in lost product value and prevent more than 255 billion cubic feet of methane from reaching the atmosphere, putting it among the largest commercial methane-mitigation efforts on record. Combined with Zeitview’s existing platform, which has inspected more than 200,000 assets across 80-plus countries, the offering shifts oil and gas operators toward continuous, predictive asset and emissions management.
Zeitview itself was founded in 2014 as DroneBase, rebranded in early 2023, and has raised roughly $174M across 11 rounds, with Valor Equity Partners leading the most recent $55M round alongside Union Square Ventures, Upfront Ventures, and Energy Transition Ventures. The Insight M deal sits inside a broader pattern of capital flowing into methane MRV (monitoring, reporting, and verification) software as U.S. EPA methane rules and the Inflation Reduction Act methane fee push operators to spend on detection technology that pays for itself in avoided fees and recovered gas.
