Punching-Shear Failure

A small-diameter initial hole drilled along a planned path before reaming to full size, commonly used in horizontal directional drilling. Subcontractors use it to verify alignment and ground conditions before committing to the full excavation scope.

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

The process of controlling, monitoring, and removing sand produced alongside oil and gas to protect wellbore equipment and surface facilities. Subcontractors may be hired to install sand screens, separators, or erosion monitoring systems. Poor sand management accelerates equipment wear and increases maintenance callouts.

A voluntary safety certification program in Canada that recognizes employers who have developed health and safety management systems that meet established standards. Required by many operators in Alberta and Western Canada.

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.

Large-scale infrastructure construction involving earthworks, bridges, roads, and foundations. Subcontractors in this sector typically supply specialised equipment, civil crews, or concrete services. Contracts are often high-value but require significant bonding and insurance capacity.

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.
