Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

SRP (Sucker Rod Pump)

A downhole artificial lift system that uses surface-driven rods to pump oil from low-pressure wells. Subcontractors are frequently called in for rod pulling, pump teardowns, and wellsite servicing work. Reliable SRP maintenance contracts can provide steady, recurring revenue for oilfield service companies.

Related Terms

Lean Construction

Industry

A project delivery approach that eliminates wasted time, materials, and labour on job sites. Subcontractors use lean methods to tighten scheduling, reduce idle crew time, and improve handoffs between trades. It often involves short-interval planning tools like the Last Planner System.

Inactive Well

Industry

A wellbore that is not currently producing or being actively operated, but has not been formally abandoned. Subcontractors may be hired for monitoring, maintenance, or eventual reclamation work on these sites. Regulatory requirements around inactive wells vary by province and can affect scope and timeline.

Early-Works

Industry

Preliminary site preparation activities awarded before a project's main contract is finalised. For subcontractors, this means mobilising early—often under a letter of intent—to handle clearing, grading, or utility work. Scope and payment terms can be limited, so review your agreement carefully before committing resources.

WCSB (Western Canadian Sedimentary Basin)

Industry

A vast sedimentary basin spanning BC, Alberta, Saskatchewan, and Manitoba that hosts Canada's largest oil and gas reserves. It is the primary operating region for most Canadian upstream field service subcontractors. Work here includes conventional drilling, oil sands operations, and pipeline construction.

Pad Construction

Industry

The process of building a level gravel or compacted surface to support drilling rigs, equipment, and site infrastructure. Subcontractors are often mobilised early to complete pad work before main drilling operations begin. Delays in pad construction can push back entire project schedules and affect downstream crew mobilisation.

Mmbbl (million Barrels)

Industry

A unit measuring crude oil volume, where one MMbbl equals one million barrels. Operators use MMbbl figures to size projects and forecast work scopes. Higher MMbbl targets typically mean longer contracts and more field service opportunities.
