SLB Products & Services
SLB’s portfolio covers much of the energy lifecycle, from subsurface evaluation and well construction to production, digital optimization, subsea systems, chemicals, artificial lift, carbon management, and new energy technologies.
Reservoir Performance
SLB’s Reservoir Performance business provides technologies for evaluating subsurface formations and improving reservoir development.
Services include wireline measurements, testing, stimulation, intervention, fluid evaluation, and reservoir characterization.
Well Construction
SLB provides equipment, technologies, and services for drilling and completing wells.
The business covers drill bits, drilling systems, measurement technologies, cementing, drilling fluids, well integrity, and related well-construction workflows.
Production Systems
SLB Production Systems helps operators bring oil and gas to the surface and maintain production over the life of an asset.
The portfolio includes completions, artificial lift, valves, surface systems, subsea systems, and production technologies.
Artificial Lift
Following the ChampionX acquisition, SLB expanded its artificial-lift portfolio.
Artificial-lift systems help maintain or increase production from wells when natural reservoir pressure is insufficient to deliver fluids efficiently to the surface.
Production Chemicals
ChampionX also expanded SLB’s production-chemistry capabilities.
Production chemicals help manage corrosion, scale, flow assurance, separation, and other operating challenges associated with oil and gas production.
Subsea Systems
SLB develops subsea production equipment and integrated subsea technologies.
These systems support offshore field development by controlling and transporting hydrocarbons from subsea wells to processing infrastructure.
Digital Energy
SLB provides digital platforms, cloud technologies, data services, AI, automation, and software for energy companies.
Its digital business generated approximately $2.66 billion in 2025 revenue.
DELFI Digital Platform
DELFI provides cloud-based digital applications and data environments for energy workflows.
It supports interpretation, modeling, drilling, production, planning, collaboration, and other technical workflows.
AI for Energy
SLB is expanding artificial intelligence across reservoir, drilling, production, and operational workflows.
The company has also introduced agentic AI and other advanced digital technologies for technical energy applications.
Data Center Solutions
SLB has expanded technology offerings connected with data centers and high-performance computing infrastructure.
The company highlighted rapid growth in Data Center Solutions as part of its 2025 strategic portfolio development.
Drilling Services
SLB provides directional drilling, measurements while drilling, logging while drilling, drilling optimization, and well-placement technologies.
These services help operators reach geological targets while improving efficiency and reducing drilling risk.
Drill Bits
SLB designs and manufactures drill bits for different formations, drilling environments, and performance objectives.
Bit technologies can be integrated with drilling systems and digital optimization workflows.
Cementing
SLB provides cementing technologies designed to isolate formations and protect well integrity.
Services include cement design, placement, evaluation, and specialty systems for complex wells.
Drilling Fluids
SLB supplies drilling-fluid technologies used to manage pressure, clean the wellbore, stabilize formations, cool equipment, and support drilling performance.
Well Testing
Well-testing services help operators understand reservoir pressure, flow capacity, fluid characteristics, and production potential.
Results support field-development, completion, and production decisions.
Wireline Services
Wireline tools collect measurements from wells to evaluate formations, fluids, casing, cement, and reservoir properties.
Wireline intervention technologies can also support well maintenance and remediation.
Stimulation
SLB offers stimulation technologies designed to improve fluid flow between the reservoir and the well.
Services can include hydraulic fracturing, acidizing, and engineered treatment programs.
Well Intervention
Well-intervention services help restore, maintain, diagnose, or improve producing wells.
Technologies can include coiled tubing, slickline, wireline, pressure-control equipment, and intervention planning.
Completions
SLB develops completion equipment that prepares wells for safe and controlled production.
Its portfolio includes sand-control, packers, flow-control systems, intelligent completions, and other downhole equipment.
Surface Production Systems
SLB provides wellheads, trees, chokes, valves, manifolds, processing equipment, and other surface-production technologies.
These systems connect wells with downstream gathering and processing infrastructure.
Reservoir Software
SLB develops modeling and interpretation software for geoscience, reservoir engineering, drilling, and production.
These applications help technical teams integrate subsurface data and evaluate development scenarios.

How to File a Complaint Against SLB
Because SLB serves commercial, industrial, institutional, and energy customers rather than ordinary retail consumers, the appropriate complaint process depends on whether the issue concerns a product, contract, invoice, safety incident, software system, employee conduct, ethics, supplier matter, or shareholder issue.
Step 1: Contact Your SLB Account or Technical Representative
For product, equipment, field-service, software, project, invoice, or technical concerns, begin with your assigned SLB account manager, project representative, service coordinator, or technical specialist. Provide the contract, purchase order, project number, location, dates, equipment identifiers, and a concise explanation of the problem. Request written confirmation that the matter has been recorded and identify the desired technical or commercial resolution.
Step 2: Use SLB’s Official Contact Channel
If the existing business representative cannot resolve the issue, use https://www.slb.com/contact-us and select the appropriate category. SLB provides separate routes for technical consultations, software escalations, invoices, suppliers, incidents, media, investor relations, and other business matters. Include earlier case references and supporting documentation so the issue can be routed to the appropriate regional or functional team.
Step 3: Use the EthicsLine for Ethics or Compliance Concerns
For bribery, fraud, harassment, conflicts of interest, compliance violations, or other misconduct concerns, use SLB’s 24-hour EthicsLine at 888-884-8849 or the company’s online EthicsPoint reporting system. SLB states that ethics allegations are classified and reviewed through its Ethics and Compliance process, with confidentiality controls and independent review procedures.
Step 4: Send Formal Corporate Correspondence
For a serious unresolved corporate matter, send written correspondence to SLB Limited, 5599 San Felipe, 17th Floor, Houston, TX 77056. Include the relevant business unit, account, contract, invoice, project, facility, previous contacts, and a chronological explanation of the complaint. For accounting or auditing concerns, correspondence can be specifically addressed to the Audit Committee through the SLB Limited Secretary.
Step 5: Use the Appropriate External Process if Necessary
If the complaint remains unresolved, external escalation depends on the matter. Contractual disputes may follow the dispute-resolution terms in the applicable agreement, workplace matters may involve labor authorities, environmental or safety incidents can involve relevant regulatory agencies, and securities concerns may involve
