Industry Glossary Term

Pressure Pumping

A well stimulation service involving the high-pressure injection of fluids — such as fracturing fluid, cement, or acid — into a wellbore to improve production or complete the well; for subcontractors, it represents a specialised, equipment-intensive scope of work that typically requires certified operators, dedicated pump trucks, and close coordination with the primary operator on site.

Related Terms

FRP (Fibre-reinforced Polymer)

Industry

A lightweight, corrosion-resistant composite material used in piping, grating, and structural components on oilfield and construction sites. Subcontractors encounter FRP in offshore platforms, chemical plants, and water treatment facilities. It requires specialised handling and cutting procedures to avoid hazardous dust exposure.

Schedule Compliance

Industry

A measure of how consistently a subcontractor completes work within the agreed timeline. Low compliance can trigger penalties, delay progress payments, or affect contract renewal. Tracking it helps field crews identify where mobilisation or scope changes are causing slippage.

EOR (Enhanced Oil Recovery)

Industry

A set of advanced extraction techniques—such as steam injection, chemical flooding, or CO2 injection—used to pull additional crude from mature or low-yield reservoirs, which drives demand for specialised field service crews, equipment operators, and maintenance contractors on long-term site assignments.

AFE (Authorization for Expenditure)

Industry

A 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.

BHA (Bottom Hole Assembly)

Industry

The collection of drilling tools and equipment at the bottom of the drill string, including the drill bit, drill collars, stabilizers, and downhole motors. For drilling subcontractors, BHA configuration directly impacts drilling performance, tool wear rates, and operational efficiency.

Subcontractor

Industry

A company hired by a general contractor or directly by an operator to perform a specific portion of work. Subcontractors often specialize in particular services or trades.
