SLB (Schlumberger)

SLB (formerly Schlumberger Limited) is a publicly listed energy-services technology company headquartered in Houston (US), Paris, The Hague, and London, founded in 1926 by the Schlumberger brothers (Conrad and Marcel) and renamed from Schlumberger to SLB in October 2022. The company is the principal global supplier of oilfield-services technology to the oil-and-gas industry, with operations across reservoir characterization, drilling, production, and the broader exploration-and-production (E&P) workflow. SLB has substantial in-house applied-AI and machine-learning research, with the DELFI cognitive E&P environment as the principal commercial AI-augmented platform for the global oil-and-gas industry, and an active research-and-publication record across geosciences and energy-AI venues. As of April 2026, SLB is one of the principal applied-AI research organizations in the global energy-services industry, with substantial commercial deployment of AI-augmented platforms across the global oil-and-gas customer base.

Origins

Schlumberger was founded in 1926 by Conrad and Marcel Schlumberger, the French physicist brothers who developed wireline well-logging technology that became the principal commercial subsurface-measurement technology for the global oil-and-gas industry. Through the 20th century, Schlumberger grew into the principal global oilfield-services company, with operations across the reservoir-characterization, drilling, well-construction, and production-systems business lines.

The 2010s saw substantial investment in cloud computing and applied-AI research across the Schlumberger product line. The 2018 launch of the DELFI cognitive E&P environment marked the principal commercial AI-augmented platform release, with cloud-based reservoir-characterization, drilling-optimization, and production-forecasting capabilities integrated into a unified workflow. DELFI was developed in close cooperation with Microsoft Azure and Google Cloud, with the cloud-deployment partnerships providing the underlying compute and platform infrastructure.

The October 2022 rename from Schlumberger to SLB signaled the strategic broadening from oil-and-gas-only into the broader energy and energy-transition businesses, with the company's positioning expanding to include carbon capture and storage, geothermal, lithium extraction, and hydrogen-related technology development. The renamed brand identity included the "energy innovation" positioning that distinguished SLB from oil-and-gas-only competitors.

The 2022 to 2026 period has continued DELFI commercial deployment alongside the broader energy-transition strategy expansion. The 2024 announcement of the Aramco partnership extended DELFI's deployment in Saudi Arabia, and the broader DELFI customer base has expanded across the principal global oil-and-gas operators.

Mission and strategy

SLB's stated mission is to deliver innovative technology and services that contribute to a balanced and sustainable energy future. The strategy combines two threads. First, the core oilfield-services business across reservoir characterization, drilling, well-construction, and production-systems, with continued applied-AI integration supporting commercial offerings. Second, the DELFI cognitive E&P environment as the principal cloud-based AI-augmented platform, with the multi-cloud deployment partnership structure supporting global customer access.

The competitive premise is that oilfield-services applications have structural requirements (subsurface uncertainty, multi-physics integration, operational safety, regulatory compliance) that differ from consumer-internet AI applications, and that an in-house applied-AI research organization with substantial commercial-platform deployment can produce energy-AI capabilities that AI-vendor alternatives cannot match.

Models and products

• DELFI cognitive E&P environment. Cloud-based AI-augmented platform for reservoir characterization, drilling optimization, production forecasting, and the broader exploration-and-production workflow.
• ML-augmented reservoir characterization. Subsurface-imaging and reservoir-modeling tooling integrated across SLB commercial offerings.
• ML-augmented drilling optimization. Drilling-program optimization and real-time drilling-decision-support tooling.
• ML-augmented production forecasting. Reservoir-performance prediction and production-optimization tooling.
• Active research-and-publication record. Across geosciences and energy-AI venues.

Distribution channels are predominantly direct enterprise sales to global oil-and-gas operators, with multi-cloud deployment partnerships (Microsoft Azure and Google Cloud) supporting customer access to DELFI.

Benchmarks and standing

SLB is not evaluated against AI benchmarks. The company's standing is measured through commercial metrics (revenue, customer-base concentration, gross margin) and applied-AI commercial-deployment metrics (DELFI customer adoption, AI-augmented platform usage).

Industry coverage has consistently characterized SLB as the principal global oilfield-services company and one of the principal applied-AI research organizations in the global energy-services industry, with DELFI as the principal validating commercial-deployment data point.

Leadership

As of April 2026, SLB's senior leadership includes:

• Olivier Le Peuch, Chief Executive Officer.
• Stephane Biguet, Chief Financial Officer.
• Senior business-line leadership across the reservoir-performance, drilling, well-construction, production-systems, and digital-and-integration organizations.
