Refers to offshore oil and gas operations conducted in water depths exceeding 300 metres, where subcontractors and field service crews must hold specialised certifications, work within stricter regulatory frameworks, and often face extended mobilisation timelines and higher equipment day-rates.

Bore Path
IndustryThe planned underground route a drill bit follows during horizontal directional drilling (HDD). Subcontractors use bore path data to plan equipment placement, crew positioning, and utility clearances. Deviations from the bore path can trigger rework costs and schedule delays.
BOPD (Barrels of Oil Per Day)
IndustryA measure of a well's or facility's daily oil production output. Operators use BOPD targets to schedule field service work, so higher rates often mean more frequent maintenance contracts and crew rotations. Subcontractors may see BOPD thresholds written into service agreements to trigger additional scope.
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.
E&P (Exploration and Production)
IndustryThe upstream segment of the oil and gas industry covering the search for and extraction of hydrocarbons, representing the primary client base that hires field service subcontractors for drilling, completions, well servicing, and site construction work. Understanding whether a client operates in E&P helps subcontractors anticipate project cycles, budget timing, and the boom-and-bust demand patterns that directly affect contract volumes and payment schedules.
Master Service Agreement (MSA)
IndustryA contract between an operator and a service company that establishes the general terms and conditions for all future work. Individual jobs are then executed under work orders or AFEs referencing the MSA.
NGL (Natural Gas Liquids)
IndustryHydrocarbons extracted from natural gas, including propane, butane, and condensate. NGL facilities and pipelines generate steady subcontract work in processing, instrumentation, and maintenance. Understanding NGL handling requirements helps crews meet site-specific safety and equipment standards.
