VRU (Vapour Recovery Unit)

The date when drilling begins on a new well. Marks the start of drilling operations.

Work performed at isolated locations far from urban centres, such as camps, wellsites, or pipeline corridors. Subcontractors must self-manage logistics, including equipment, consumables, and crew rotations. Mobilisation costs and travel time significantly affect how contracts should be priced.

The process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.

The horizontal section of a directionally drilled well, extending sideways through the target formation. Laterals can stretch several kilometres, requiring extended crew mobilisations and staged service scopes. Subcontractors should clarify lateral length upfront, as it directly affects equipment needs and job duration.

When operators strictly control spending and delay or cancel projects to protect their balance sheets. For subcontractors, this means fewer awarded contracts, reduced scopes, and tighter bid competition. Expect slower mobilisation timelines and more rigorous cost justification from clients.

A designated area of Crown or freehold land divided for exploration and production rights. Subcontractors often mobilise crews and equipment according to which land blocks an operator holds active licences for. Work scopes, access agreements, and surface rights are typically tied to specific block boundaries.

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.
