MEP (Mechanical, Electrical, and Plumbing)

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 real-time data acquisition process used during directional drilling that transmits downhole measurements — such as wellbore trajectory, formation data, and tool orientation — to surface crews without interrupting operations. For subcontractors, MWD services represent a specialised scope of work requiring certified technicians and dedicated equipment, often billed as a separate line item on drilling contracts.

A structural tower erected over a mine shaft to support hoisting equipment and guide cables. Subcontractors working near headframes must coordinate lifts and personnel movement carefully. Access restrictions and load limits are strictly enforced on-site.

A drilling approach where well placement decisions are guided by real-time gas readings from formation data. Subcontractors should expect frequent operational pauses for data evaluation and possible scope changes. Mud logging and wellsite geology crews are typically in high demand on these programmes.

An unmanned, tethered underwater robot used to inspect, survey, or perform work on subsea pipelines, wellheads, and structures — subcontractors providing ROV services typically require specialised operators and vessels, and should account for mobilisation costs and standby rates when bidding these scopes.

A designated location where materials, parts, or equipment are staged for quick deployment to active job sites. Subcontractors often draw inventory from a client's stockpoint rather than sourcing independently. Knowing stockpoint locations reduces mobilisation delays and simplifies cost tracking.

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.
