Surface Coil System

A process where steam is pumped through wellbore tubing to heat and mobilise heavy oil or bitumen. Subcontractors are often engaged for equipment operation, line connections, and monitoring during circulation cycles. Scope can expand quickly, so confirm change-order terms before mobilising.

ROP measures how fast a drill bit advances through rock, usually in metres per hour. Subcontractors use it to estimate job duration and crew scheduling. Faster ROP can mean shorter contracts but higher equipment wear costs.

A controlled channel or outlet designed to safely redirect excess water away from a work site. Subcontractors may be responsible for installing, maintaining, or working around spillways during site grading, civil, or environmental scopes.

A notice issued by a client or prime contractor to identify qualified subcontractors before a formal tender is released. Responding helps get your company on the bidders list. It is not a contract offer, but skipping it can mean missing the actual bid.

A facility that measures the volume or flow rate of oil, gas, or water moving through a pipeline. Subcontractors are often mobilised to install, calibrate, inspect, or maintain metering equipment at these sites. Work scope can include instrumentation, piping, civil, and electrical trades.

The decommissioning of wells, pipelines, or infrastructure located in shallow coastal waters. Subcontractors typically handle diving operations, cutting, capping, and seabed remediation work. Regulatory requirements are strict, so current certifications and environmental compliance documentation are essential before mobilising.
