NGL (Natural Gas Liquids)

A complete set of hydraulic fracturing equipment deployed together at a well site, including pumps, blenders, and support units. For subcontractors, a frac fleet mobilisation often triggers large, time-sensitive labour and equipment contracts. Knowing fleet size helps you scope crew requirements and forecast workload duration.

The complete package of equipment, personnel, and services required to drill a well, which determines the scope of work subcontractors are hired into — whether supplying a single service line or multiple integrated components across the operation.

The process of installing pipe, casing, or tubing strings into a wellbore during drilling or completion operations. Subcontractors providing tubular running services supply specialised crews and equipment such as power tongs and elevators. Accurate job scoping is critical, as rig time is costly and delays directly affect invoicing and contract performance.

Underground storage facilities, typically salt caverns, used to store hydrocarbons like natural gas or crude oil. Subcontractors may be engaged for cavern construction, well drilling, piping, and surface facility work. Projects often involve specialised equipment and compressed timelines tied to storage demand cycles.

A standard measure of a well site's or facility's total energy output, combining oil, gas, and NGLs into one comparable unit. Operators use BOE/D figures to size projects and determine crew and equipment requirements. Higher BOE/D rates typically signal larger scopes of work and longer service contracts for subcontractors.

The percentage of scheduled time that equipment is operational and available for use on a job site. For subcontractors, high uptime directly affects billing hours, client satisfaction, and contract renewals. Downtime caused by mechanical failure or poor maintenance often falls on the subcontractor to remedy at their own cost.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
