A well-site service that monitors drilling fluid returns to detect hydrocarbons and analyse formation data in real time. Subcontractors provide specialised technicians and instrumentation units for this work. It is commonly scoped as a standalone package within a drilling contract.

Completion Crews
IndustrySpecialised teams mobilised after drilling to prepare a well for production. For subcontractors, they represent a distinct scope of work with separate contracts, timelines, and crew requirements. Demand is tied directly to operator completion schedules, affecting short-notice mobilisation and billing cycles.
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.
Hydrovac
IndustryA truck-mounted unit that uses pressurised water and a vacuum system to excavate soil safely around buried utilities. Subcontractors are frequently hired for hydrovac work on pipeline, civil, and utility projects. It is preferred over mechanical digging in areas with high strike risk.
PCP (Progressive Cavity Pump)
IndustryA rotary pump used in oil and gas production to lift heavy or viscous fluids from wellbores. Subcontractors are frequently hired for PCP installation, maintenance, and rod-string servicing. Familiarity with drive heads, stators, and rotors is essential for field technicians working these jobs.
Pre-Salt
IndustryRefers to oil reservoirs located beneath thick layers of underground salt, typically in deepwater offshore basins. For subcontractors, pre-salt projects involve specialised equipment, extended mobilisation timelines, and higher operational complexity. Expect longer contract cycles and stricter certification requirements from operators.
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.
