The rate at which a well's production drops over time without operator intervention. For subcontractors, this signals reduced worksite activity and fewer service calls as output falls. Anticipating decline helps crews and companies plan for shifting demand across a field.
Natural Decline Rate
Related Terms
DRA (Drag-reducing Agent)
IndustryA chemical additive injected into pipelines to reduce turbulence and increase flow rates without adding compression. Subcontractors handling pipeline operations or chemical injection work may be scoped to install, maintain, or monitor DRA injection skids. Understanding DRA systems helps crews execute chemical handling tasks safely and meet operator flow assurance targets.
Onshore Acreage
IndustryLand-based areas leased or licensed by operators for exploration and production activities. For subcontractors, it defines where field work is scoped, mobilised, and contracted. Acreage size and location directly affect crew logistics, travel costs, and service demand.
PPA (Power Purchase Agreement)
IndustryA long-term contract where a buyer agrees to purchase electricity from a generator at a fixed price. For subcontractors, PPAs on large sites can affect whether temporary or permanent power infrastructure is in scope. Understanding site power arrangements helps clarify mobilisation costs and equipment requirements.
Well Testing
IndustryA series of controlled flow and pressure measurements performed on a newly drilled or existing well to evaluate its production potential and reservoir characteristics; for subcontractors, this work often involves deploying and operating specialised equipment such as separators, flowback units, and data acquisition systems under tightly scheduled, high-priority conditions.
BPD (Barrels Per Day)
IndustryA measure of a well's or facility's daily oil output. Higher BPD typically means greater activity levels, more crews on site, and increased service demand. Subcontractors often see scope and call-out frequency tied directly to a client's BPD targets.
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.
