Compression Station

The planned underground route a drill bit follows during horizontal directional drilling (HDD). Subcontractors use bore path data to plan equipment placement, crew positioning, and utility clearances. Deviations from the bore path can trigger rework costs and schedule delays.

The final phase of pipeline construction where systems are tested, cleaned, and activated before handover to the operator. Subcontractors are often mobilised for hydrotesting, pigging, and tie-in work during this stage. Scope can expand quickly, so track change orders closely.

Products created by processing or transforming raw materials supplied under a contract, such as fabricated components or treated fluids. Subcontractors must clarify ownership rights over derivative goods before work begins. Contracts often assign these rights to the prime contractor or client by default.

Mesh filters mounted on shale shakers that separate drill cuttings from drilling fluid on the rig. Subcontractors handling fluid management or solids control must track screen condition and swap them regularly. Damaged or plugged screens slow operations and can trigger downtime charges against your crew.

Specialised equipment run into a wellbore to perform drilling, measurement, or completion tasks. For subcontractors, these tools often require certified handling, transport, and make-up procedures. Improper use can trigger costly liability or contract disputes.

A geophysical mapping operation that uses sound waves to image underground formations before drilling begins. Subcontractors are hired to deploy geophones, vibroseis trucks, or marine streamers across large survey grids. Work is often remote and time-sensitive, with crews mobilising quickly once permits are secured.

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.
