Mmcf/d (million Cubic Feet Per Day)

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.

A cone-shaped separation device that removes solids or liquids from drilling fluids using centrifugal force. Subcontractors service and maintain these units on drilling rigs and fluid processing systems. Proper handling requires familiarity with high-pressure fluid systems and waste disposal regulations.

A secondary oil recovery method where water is injected into a reservoir to maintain pressure and push oil toward production wells. Subcontractors support injection well drilling, pump installation, pipeline tie-ins, and ongoing facility maintenance. Scopes are often long-term, requiring sustained crew availability and specialised equipment.

A surface preparation method that uses high-pressure propelled media (sand, steel grit, or slag) to clean and profile metal surfaces before coating or painting. Subcontractors performing this work typically require specialised equipment, trained operators, and site-specific permits. It is common in pipeline, vessel, and structural steel maintenance scopes.

Pipelines 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.

A unit measuring pressure in pipelines, hydraulic systems, and wellhead equipment. Subcontractors must verify PSI ratings when selecting tools, hoses, and fittings for safe operation. Exceeding rated PSI limits can trigger equipment failure, injuries, and liability.

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.
