The process of defining the boundaries and quantity of an oil, gas, or mineral deposit through appraisal drilling and testing. For subcontractors, it signals a sustained work programme requiring crew, equipment, and logistical planning. Delineation phases often drive multi-month contracts for drilling, completions, and field services.
Resource Delineation
Related Terms
Heads of Agreement (hoa)
IndustryA preliminary document outlining the key commercial terms agreed between parties before a formal contract is finalised. For subcontractors, it signals serious intent but is not always legally binding. Avoid mobilising crews or purchasing materials based solely on an HoA.
Multi-Well Pad
IndustryA single surface location where multiple wells are drilled and completed in sequence. For subcontractors, this means extended site presence, higher mobilisation value, and repeated service cycles from one location. Scheduling and crew continuity are critical to securing ongoing work across the pad.
Offtake Agreement
IndustryA long-term contract where a buyer commits to purchasing a set volume of product from a producer. For subcontractors, these agreements signal stable, ongoing site activity and sustained demand for field services. They often underpin project financing, making worksites more financially secure for service providers.
Brine Development
IndustryThe process of producing and managing saltwater solutions used in well completion, workover, and drilling operations. Subcontractors may be engaged for fluid handling, storage, transport, or disposal services. Scope can vary widely, so confirm fluid specifications and disposal requirements before mobilising.
Modular Water Storage
IndustryPortable, stackable tank systems used on remote job sites to store potable, process, or wastewater. Subcontractors deploy them quickly without permanent infrastructure. Common on pipeline, camp, and frac support contracts.
Pilot Bore
IndustryA small-diameter initial hole drilled along a planned path before reaming to full size, commonly used in horizontal directional drilling. Subcontractors use it to verify alignment and ground conditions before committing to the full excavation scope.
