VLCC (Very Large Crude Carrier)

A contractual obligation by a producer or operator to move a set volume of product through a pipeline over a defined period. These agreements often drive project timelines and mobilisation schedules for field service subcontractors. Steady shipper commitments signal stable, longer-term work opportunities in a given region.

A network of pipelines, valves, and infrastructure that moves oil, gas, or utilities from a main supply point to end users. Subcontractors are often hired to install, inspect, or maintain these systems. Work scope can include trenching, pipe fitting, and pressure testing across large service areas.

A system of electric cables or steam lines wrapped around pipes to prevent freezing or maintain process temperatures. Subcontractors are often hired to install, inspect, and commission these systems during turnarounds or new construction. Common in cold-climate facilities handling water lines, instrumentation, and process piping.

A measure of a well's or facility's daily oil production output. Operators use BOPD targets to schedule field service work, so higher rates often mean more frequent maintenance contracts and crew rotations. Subcontractors may see BOPD thresholds written into service agreements to trigger additional scope.

A trenchless pipe rehabilitation method where a resin-saturated liner is inserted into a damaged pipe and hardened in place. Subcontractors typically provide specialised crews, inversion or pull-in equipment, and UV or steam curing systems. Common in municipal, oil and gas, and industrial pipeline maintenance scopes.

Hydrocarbons discovered but not yet approved for development due to technical or commercial barriers. For subcontractors, these projects exist in planning stages but carry no guaranteed work orders. Mobilisation timelines remain uncertain until operator sanction is confirmed.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.

How Rig Count Trends Affect Subcontractor Demand and What to Do About It

Rig counts are the earliest signal of where field service work is heading. Learn how to read drilling activity trends, anticipate demand shifts, and position your crew before the phone stops ringing.

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.
