Phase Gate

A U.S. trade association representing merit-shop contractors in construction and industrial sectors. Subcontractors use ABC membership for training resources, safety programmes, and industry networking. Membership can also signal credibility when bidding on open-shop projects.

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.

A designated strip of land reserved for pipeline installation, operation, and maintenance. Subcontractors must confine all work, equipment, and materials within its boundaries. Corridor limits directly affect site access, staging areas, and crew movement on linear projects.

A subcontractor's collection of heat-generating equipment, such as steam generators, line heaters, and freeze protection units. These assets are mobilised for cold-weather operations, pipeline conditioning, or process heating on oil and gas sites. Fleet size directly affects a subcontractor's capacity to bid on thermal service contracts.

Adding a parallel pipeline segment alongside an existing line to increase flow capacity. For subcontractors, it means mobilising crews and equipment for a new build tied into an active system. Expect phased work scopes, tie-in shutdowns, and strict coordination with the operator.

Two horizontal wells drilled together — one injector, one producer — used in SAGD (Steam-Assisted Gravity Drainage) operations. Subcontractors often mobilise crews and equipment to service both wells simultaneously. Expect back-to-back work scopes and coordinated scheduling across a shared pad site.

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.
