Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Resource Delineation

The process of defining the boundaries and quantity of an oil, gas, or mineral deposit through appraisal drilling and testing. For subcontractors, it signals a sustained work programme requiring crew, equipment, and logistical planning. Delineation phases often drive multi-month contracts for drilling, completions, and field services.

Related Terms

Run-Life

Industry

The expected operational lifespan of a downhole tool or piece of equipment before it requires servicing or replacement. For subcontractors, run-life directly affects rental billing cycles, maintenance scheduling, and equipment mobilisation costs. Shorter run-lives can erode margins if replacement or redress costs aren't priced into the contract.

Satellite Jetty

Industry

A secondary or auxiliary dock located away from a main terminal, used to load or offload vessels at remote points along a waterway. Subcontractors may be mobilised specifically to satellite jetties for marine construction, maintenance, or material handling work. Access and logistics can differ significantly from main terminals, affecting crew scheduling and equipment mobilisation.

Carbonate Formation

Industry

A type of subsurface rock layer—primarily limestone or dolomite—that subcontractors may encounter during drilling, completions, or civil excavation work, often requiring specialised equipment, bit selections, or modified drilling programmes due to its hardness and tendency to cause lost circulation events.

COR (Certificate of Recognition)

Industry

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.

Cold-Milled Asphalt

Industry

Reclaimed pavement material produced by grinding existing asphalt surfaces without heat. Subcontractors encounter it during road restoration work on well pads, pipeline rights-of-way, and industrial sites. It is commonly reused as base material, reducing disposal costs and material haul-off requirements.

Gathering System

Industry

A network of pipelines, compressors, and facilities that collect hydrocarbons from wellheads and move them to processing points. Subcontractors frequently support construction, inspection, and maintenance work across these systems. Scopes can span remote multi-well pads, requiring strong logistics and crew coordination.
