A method of tracking an underground drill head's position by walking the surface above it with a handheld receiver. The receiver picks up a signal from a transmitter housed in the drill head. Subcontractors use this to guide directional boring and confirm depth in real time.

Transmission Tie-in
IndustryA connection point where a new pipeline is joined to an existing high-pressure transmission system. Subcontractors typically handle welding, purging, and pressure testing during a planned outage window. Tie-in scopes often require strict scheduling coordination and certified welding procedures.
Condensate Play
IndustryA development area targeting light liquid hydrocarbons that separate from natural gas at surface. These plays often require specialised separator handling and fluid management equipment. Subcontractors can expect steady demand for well servicing, trucking, and processing facility work.
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.
Frac Sand Hauling
IndustryThe trucking of proppant (silica sand) from storage terminals to active frac sites. Subcontractors operate on tight dispatch schedules to maintain continuous sand supply during pumping operations. Contracts often include standby rates for wait time at the wellsite.
Well Program
IndustryA technical document outlining the planned scope, procedures, and specifications for drilling or completing a well. Subcontractors use it to understand required services, equipment, and sequencing before mobilising. It directly affects how you scope work and price your bid.
Radial Telescopic Conveyor
IndustryA mobile conveyor system that extends in length and swings in an arc to stockpile bulk materials across a wide area. Commonly used on pipeline, mining, and civil construction sites for aggregate, gravel, or spoil management. Subcontractors operating this equipment typically require certified operators and may be responsible for setup, teardown, and repositioning.
