Industry Glossary Term

Pad Drilling

A method where multiple wells are drilled from a single surface location, or pad. For subcontractors, this means sustained, back-to-back work cycles with minimal rig-up and tear-down time. Efficient mobilisation and crew scheduling are critical to maintaining productivity across the pad.

Related Terms

Leasehold

Industry

Land or mineral rights an operator has legally secured through a lease agreement with the landowner or Crown. Subcontractors typically work within leasehold boundaries, so access, permitting, and site rules are set by the operator holding the lease. Understanding leasehold limits helps crews avoid trespassing on adjacent unlicensed areas.

Private Activity Bonds

Industry

Tax-exempt bonds issued by governments to finance private infrastructure projects like pipelines or terminals. Subcontractors may work on bond-funded projects, which often carry strict procurement and reporting requirements. Understanding this can affect how you bid and invoice on qualifying jobs.

Negative Gas Prices

Industry

Occurs when oversupply forces producers to pay buyers to take gas, signalling severe market stress. For subcontractors, this often triggers rapid project suspensions, deferred work orders, and delayed payments. Expect scope reductions and early contract terminations when prices turn negative.

Refinery Throughput

Industry

The volume of crude oil a refinery processes over a set period, typically measured in barrels per day. Higher throughput means more maintenance, turnaround, and inspection work for subcontractors. Expect busier scopes and tighter schedules when a client ramps up processing capacity.

Co2 Storage (carbon Dioxide Storage)

Industry

The permanent underground injection of captured CO2 into geological formations like depleted reservoirs or saline aquifers. Subcontractors may support well preparation, pipeline installation, monitoring equipment, and injection operations. Demand for specialised field crews is growing as carbon capture projects expand across Canada.

Spot Work

Industry

Short-term, unplanned jobs awarded without a long-term contract, typically filled on short notice. Subcontractors are engaged for a single scope or site visit at a negotiated day rate. Common in shutdown, turnaround, and emergency maintenance situations.
