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.
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.
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.
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.
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.
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
