Crane Mats
IndustryLarge interlocked timber or composite panels placed under crane outriggers to distribute load on soft or unstable ground. Subcontractors often supply, transport, and install them as part of site prep scopes. Rental and mobilisation costs should be clearly itemised in your quote.
Appraisal Drilling
IndustryDrilling program that follows an initial discovery to confirm reservoir size and commercial viability. For subcontractors, it means short-term, high-intensity scopes between exploration and full development phases. Mobilisation windows can be tight and contract durations unpredictable.
Custody Transfer
IndustryThe 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.
Pipeline Open Season
IndustryA formal period when a pipeline operator solicits capacity commitments from shippers before building or expanding a line. For subcontractors, it signals upcoming construction and maintenance work. Winning bids during this phase often trigger mobilisation timelines and crew planning.
Workover
IndustryOperations performed on an existing well to restore, maintain, or improve production. Includes activities like recompletions, artificial lift installation, and remedial cementing.
AFE (Authorization for Expenditure)
IndustryA budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.
