The evaluation of reservoir rock and fluid properties using well log data and core samples. Results determine whether a well is worth completing, directly affecting drilling programme scope and subcontractor workload. Field crews support this work through wireline logging, coring, and fluid sampling operations.

A formal document issued by a client or general contractor authorising a subcontractor to perform a specific scope of work. It outlines the job details, location, timeline, and agreed rate. Subcontractors typically cannot invoice without a valid work order number.

A non-destructive digging method that uses high-pressure water or air to loosen soil, then suctions the debris into a holding tank. Commonly used for safe excavation around buried utilities, pipelines, and underground infrastructure. Subcontractors are often hired for this work during tie-ins, facility upgrades, or pre-dig utility locates.

A government auction where energy companies bid for the right to explore and develop specific land or offshore blocks. Winning bids signal upcoming exploration activity, which often leads to new work opportunities for field service subcontractors. Tracking lease sales helps companies anticipate demand and position crews and equipment accordingly.

A natural clay mineral used in drilling fluids to stabilise boreholes and suspend drill cuttings. Subcontractors handling bentonite slurry must follow site-specific mixing and disposal procedures. Improper handling can trigger environmental compliance issues and project delays.

A pre-project assessment that evaluates whether a scope of work is technically and financially viable. For subcontractors, it signals early-stage work that may lead to awarded contracts. Participating in feasibility work can position your company for the larger project bid.
