A method of injecting a secondary fuel, such as natural gas or propane, into a diesel engine's air intake to supplement combustion. It reduces fuel costs and emissions on long-running field equipment. Subcontractors should verify fumigation setups meet emissions compliance requirements in their operating jurisdiction.

Cavern Storage
IndustryUnderground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.
Shut-In Production
IndustryA well or facility that has been temporarily halted from producing oil or gas. For subcontractors, shut-ins often mean suspended work orders and delayed invoicing. Confirm contract terms around standby rates before production stops.
Step-Out Drilling
IndustryDrilling wells at increasing distances from a proven discovery to test the boundaries of a reservoir. For subcontractors, it signals extended mobilisation cycles and potential new work corridors. Expect shifting logistics, camp requirements, and crew rotations as operators push further from existing infrastructure.
Triplex Mud Pump
IndustryA three-cylinder reciprocating pump used on drilling rigs to circulate drilling fluid down the wellbore. Subcontractors are often hired to operate, maintain, or repair these high-pressure units. Reliable pump performance is critical — downtime directly impacts rig schedules and your contract standing.
Carbon Capture
IndustryThe process of collecting and storing CO2 emissions from industrial sites before they reach the atmosphere. For subcontractors, it means growing work opportunities in facility retrofits, pipeline installation, and compression equipment servicing. Familiarity with CCS (Carbon Capture and Storage) infrastructure is increasingly expected on energy transition projects.
Bentonite
IndustryA natural clay mineral used in drilling fluids to stabilise boreholes and suspend drill cuttings. Subcontractors handling bentonite slurry must follow site-specific mixing and disposal procedures. Improper handling can trigger environmental compliance issues and project delays.
