A series of controlled flow and pressure measurements performed on a newly drilled or existing well to evaluate its production potential and reservoir characteristics; for subcontractors, this work often involves deploying and operating specialised equipment such as separators, flowback units, and data acquisition systems under tightly scheduled, high-priority conditions.
Well Testing

Ngl (natural Gas Liquid) Fractionator
IndustryA processing facility that separates mixed natural gas liquids into individual products like propane, butane, and ethane. Subcontractors often work these sites for maintenance, turnarounds, and equipment servicing. Fractionators operate continuously, so field crews should expect shift-based schedules and strict hot-work permitting.
Mmtpa (million Metric Tons Per Annum)
IndustryA measure of annual production or throughput capacity at LNG, mining, or pipeline facilities. Subcontractors use it to gauge project scale and estimate long-term scope of maintenance or construction work. Higher MMtpa ratings typically signal larger crews, longer contracts, and more equipment requirements.
Saas (software As a Service)
IndustryCloud-based software you access via subscription instead of buying and installing it outright. For subcontractors, this covers tools like invoicing, scheduling, and compliance tracking platforms. You pay a recurring fee and can access the software from any jobsite device.
Takeaway Capacity
IndustryThe available pipeline, trucking, or rail infrastructure to move produced oil, gas, or water away from a wellsite or facility. When takeaway capacity is constrained, operators may shut in wells or delay projects, directly reducing field service work volumes. Subcontractors should monitor regional takeaway conditions as they signal upcoming slowdowns or surges in activity.
Minimum Work Program
IndustryA contractually obligated set of activities and expenditures an operator must complete within a set timeframe, typically tied to a licence or lease agreement; for subcontractors, this creates predictable scopes of work and mobilisation opportunities as operators must execute these commitments or risk losing their rights to the asset.
SAGD (Steam Assisted Gravity Drainage)
IndustryA heavy oil extraction method using paired horizontal wells where steam is injected into the upper well to heat bitumen, allowing it to drain by gravity to the lower production well. Creates specialized maintenance and service opportunities for subcontractors in steam generation equipment, wellhead systems, and pipeline infrastructure at oil sands operations.
