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.
Steam Circulation
Related Terms
Gas-Directed Rig Count
IndustryThe number of drilling rigs actively targeting natural gas formations at a given time. A rising gas-directed rig count signals increased demand for field services and subcontractor crews. Tracking this metric helps you anticipate work volumes and mobilisation timelines in gas-heavy basins.
Development Sanction
IndustryThe formal approval by an operator or project owner to proceed with full-scale field development. For subcontractors, it signals that major contracts, mobilisation, and field work are imminent. It marks the point where scopes of work move from planning to active procurement.
Field Gathering Lines
IndustryPipelines that collect oil, gas, or water from individual wellheads and route it to a central processing facility. Subcontractors frequently work on installation, inspection, and maintenance of these lines. Knowing the layout is essential for safe excavation and tie-in work.
Primary Term
IndustryThe fixed initial period of a service contract during which either party is typically locked in. For subcontractors, it sets the guaranteed window to recover mobilisation costs and generate revenue. Work orders or rates often cannot be renegotiated until this period expires.
Frac Fleet
IndustryA 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.
Trenchless
IndustryA method of installing or repairing underground pipelines and conduits without open excavation. Techniques include horizontal directional drilling (HDD) and pipe bursting. Subcontractors working trenchless scopes need specialised equipment and certified operators.
