Oil-Directed Drilling

Status indicating a drilling rig has been formally stood down and all associated services are no longer required. For subcontractors, it triggers demobilisation, final invoice submission, and crew release. Contracts often specify notice periods and standby rates tied to this status.

The replaceable filtering surfaces installed in vibratory shakers and separators on drilling and processing sites. Types include wire mesh, polyurethane, and rubber panels, each suited to different material grades. Subcontractors are often responsible for sourcing, swapping, and disposing of worn screen media during operations.

A lab process where gas is measured as it releases from rock core samples pulled during drilling. Subcontractors handling or transporting cores must follow strict protocols to preserve sample integrity. Mishandling can compromise data and trigger costly disputes with operators.

Underground storage facilities, typically salt caverns, used to store hydrocarbons like natural gas or crude oil. Subcontractors may be engaged for cavern construction, well drilling, piping, and surface facility work. Projects often involve specialised equipment and compressed timelines tied to storage demand cycles.

The regulated distance between wellbores on a pad or lease area. Tighter spacing means more wells drilled closer together, increasing crew density and equipment demand. Subcontractors should anticipate compressed timelines and overlapping scopes when spacing is tight.

A lump-sum payment made by an operator to secure rights to a lease block, separate from royalties. For subcontractors, a large bonus bid signals operator commitment and can indicate upcoming project activity in that area.

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.
