Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

The treatment of raw natural gas to remove impurities and separate saleable products like propane and condensate. Processing plants are major work sites for subcontractors providing maintenance, instrumentation, and turnaround services. Scopes can be large and ongoing, making them reliable sources of repeat field work.

Related Terms

Pjm (pennsylvania-New Jersey-Maryland) Interconnection Queue

Industry

A waiting list managed by PJM for new power generation and transmission projects seeking grid connection approval. Subcontractors use it to track upcoming infrastructure builds and time their bids accordingly. Long queue backlogs signal sustained field work demand in the PJM service territory.

Alliance Contract

Industry

A long-term agreement where a subcontractor and operator share risks, costs, and rewards on a project. Both parties collaborate closely rather than working at arm's length. Performance incentives and pain/gain sharing are common features.

Substrate

Industry

The base material or surface that a coating, lining, or treatment is applied to, such as steel pipe, concrete, or wood. Subcontractors must assess substrate condition before starting surface prep or application work. Poor substrate quality can affect adhesion, warranty, and job acceptance.

Sanctioned Field

Industry

A field development that has received formal investment approval from the operator or project owner. For subcontractors, sanction signals that contracts, mobilisation, and work orders are imminent. It marks the transition from planning to active field execution.

Triplex Mud Pump

Industry

A three-cylinder reciprocating pump used on drilling rigs to circulate drilling fluid down the wellbore. Subcontractors are often hired to operate, maintain, or repair these high-pressure units. Reliable pump performance is critical — downtime directly impacts rig schedules and your contract standing.

Run Schedule

Industry

A timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.
