A rock formation believed to contain oil or gas, targeted for drilling or evaluation. Subcontractors are often mobilised to support exploration work within these zones. Scope and duration of field service contracts may depend on how many prospective intervals a well will test.
Prospective Interval
Related Terms
Shallow-Water
IndustryOffshore operating zones typically under 500 feet of water depth. For subcontractors, these sites use jack-up rigs and barges rather than deepwater vessels. Crew access, equipment requirements, and mobilisation costs differ significantly from deepwater scopes.
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.
Portable Crusher
IndustryA mobile machine that breaks down rock, concrete, or aggregate on-site, eliminating haul-off costs. Subcontractors often supply or operate these units under equipment rental or crushing contracts. Commonly used in pipeline trenching, site prep, and demolition scopes.
Ip120 (initial Production 120-Day Rate)
IndustryThe average daily production output of a new well over its first 120 days. Operators use this benchmark to schedule and extend field service contracts. Strong IP120 results often trigger follow-on work for completions and production crews.
Turnkey
IndustryA contract where the subcontractor delivers a fully completed scope for a fixed price, assuming all cost and schedule risk. The client pays only upon project completion, not for time or materials spent. This model demands tight cost control, as overruns come directly out of your margin.
SPMT (Self-propelled Modular Transporter)
IndustryA multi-axle hydraulic platform vehicle used to move oversized modules, vessels, or heavy equipment on job sites. Subcontractors working heavy lifts or module installation scopes often coordinate directly with SPMT crews. Understanding load-out and transport sequencing is critical for scheduling your own work around these moves.
