Adding a parallel pipeline segment alongside an existing line to increase flow capacity. For subcontractors, it means mobilising crews and equipment for a new build tied into an active system. Expect phased work scopes, tie-in shutdowns, and strict coordination with the operator.

A standardised measure combining oil, gas, and NGL output into a single daily production figure. Operators use it to size contracts and scope field service requirements. Higher BOEPD targets typically mean more crews, equipment, and sustained subcontractor workload.

The company that holds the rights to develop an oil and gas property and manages day-to-day operations. Operators hire subcontractors and service companies to perform various tasks.

Steel pipe installed in a wellbore to provide structural integrity and prevent contamination between different geological formations, requiring specialized installation and cementing services that subcontractors frequently provide during drilling operations.

The formal handover point where ownership or responsibility for a measured quantity of oil, gas, or other product moves from one party to another — typically triggering billing, invoicing, or contractual obligations for subcontractors involved in metering, transport, or handling operations. Field service crews working custody transfer points must ensure measurements are accurate and fully documented, as discrepancies can directly affect client invoices and liability.

A self-propelled vessel equipped with a drilling rig used for offshore exploration and production in deepwater locations, which subcontractors may be mobilised to for specialised services such as equipment maintenance, inspection, or crew support under strict offshore safety and logistical requirements.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.
