Oilfield Support Services
Overview
Our Oilfield Support Services are strategically designed to provide end-to-end operational support for both offshore and onshore energy developments. With a robust combination of global partnerships and specialized technical expertise, we enable our clients to achieve operational excellence, asset integrity, and lifecycle cost optimization across complex project environments.
Our services are delivered through three core units:
- Procurement and Supply Chain Management
- Global Maintenance Contracts
- Commissioning and Startup services
Procurement & Supply Chain Management
The Procurement and Supply Chain Management unit is a vital extension of IESL’s EPIM framework and plays a strategic role in ensuring the timely availability of critical materials, equipment, and services that support safe and efficient operations. These services are designed to optimize sourcing, reduce costs, ensure compliance, and improve supply reliability across upstream, midstream, and downstream operations.

Global Sourcing & Vendor Management
- Sourcing & Procurement: From mechanical, electrical, instrumentation, and process equipment to bulk materials (e.g., pipes, valves, structural steel) and specialty parts from OEM.
- Vendor Engagement: We manage both international and local suppliers through rigorous onboarding, audits, and capability assessments—curating approved vendor lists (AVLs).
- Contract Management: Our negotiations cover pricing, framework agreements, SLAs, KPIs, risk-sharing, and warranties.
- Quality Assurance: We coordinate Factory Acceptance Testing (FAT), pre-dispatch checks, third-party inspections, and review vital documentation.
End-to-End Supply Chain Coordination
Covering everything from purchase orders to handover at point of use, our comprehensive services include:
- Logistics & Freight: Coordination of air, sea, and land transportation, working with freight forwarders, carriers, and customs brokers.
- Customs & Documentation: HTS classification, import/export permits, tax exemptions, and pre-shipment compliance.
- Warehousing & Inventory: Temporary storage solutions, inventory tracking, condition-sensitive handling, preservation, and Just-In-Time (JIT) delivery planning.
Supported by a robust international network, we ensure equipment and spares meet stringent API, ISO, ASME, and IEC standards—delivered with transparency, compliance, and precision.
Compliance & Risk Management
Our procurement activities adhere to legal, regulatory, and ethical standards while proactively identifying and mitigating potential risks. This function encompasses supplier due diligence, anti-corruption compliance, contract risk assessments, and adherence to international trade regulations. It also involves implementing transparent procurement practices, managing quality assurance through inspections and certifications, and ensuring environmental, social, and governance (ESG) standards are upheld throughout the supply chain.
