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.
Run-Life
Related Terms
Midstream Infrastructure
IndustryThe pipelines, compressor stations, and processing facilities that move and condition product between the wellhead and end markets. For subcontractors, it represents a major source of maintenance, construction, and inspection work. Contracts here often involve long project timelines and strict regulatory oversight.
Transmission Upgrades
IndustryLarge-scale projects to expand or modernise pipeline or power transmission infrastructure. For subcontractors, these generate significant work in welding, civil prep, and equipment installation. Scopes are often phased, requiring flexible crew deployment and quick mobilisation.
TIC (Total Installed Cost)
IndustryThe full cost of completing a scope of work, including labour, equipment, materials, and indirect expenses. Subcontractors use TIC to build accurate bids and avoid underpricing complex field installations. Owners and GCs often benchmark TIC when evaluating competing quotes.
Onshore
IndustryRefers to oil and gas or construction operations located on land, as opposed to offshore or marine environments. For subcontractors, onshore work typically means different mobilisation logistics, certification requirements, and rate structures. Most Canadian field service activity in Alberta and Saskatchewan is onshore.
Class 8
IndustryThe heaviest category of commercial trucks, rated at over 33,001 lbs gross vehicle weight. Common in oil and gas field work for hauling heavy equipment, frac sand, and pipe. Operators require a Class 1 licence in Canada.
Gas Processing
IndustryThe treatment of raw natural gas to remove impurities and separate saleable products like propane and condensate. Processing plants are major work sites for subcontractors providing maintenance, instrumentation, and turnaround services. Scopes can be large and ongoing, making them reliable sources of repeat field work.
