Infill Drilling

Specialised 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.

A chemical additive injected into pipelines to reduce turbulence and increase flow rates without adding compression. Subcontractors handling pipeline operations or chemical injection work may be scoped to install, maintain, or monitor DRA injection skids. Understanding DRA systems helps crews execute chemical handling tasks safely and meet operator flow assurance targets.

A large geographic region containing shale rock formations targeted for oil and gas extraction through horizontal drilling and hydraulic fracturing. For subcontractors, shale basins like the Montney or Duvernay represent high-volume, multi-year work corridors. Expect cyclical demand, remote mobilisation, and repeat frac and completions contracts.

A deal where a subcontractor gains equity or a stake in a project by completing defined work or spending milestones. Common in junior oil and gas ventures where cash is tight. Your services effectively buy you into the asset rather than just earning a fee.

A 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.

Reclaimed pavement material produced by grinding existing asphalt surfaces without heat. Subcontractors encounter it during road restoration work on well pads, pipeline rights-of-way, and industrial sites. It is commonly reused as base material, reducing disposal costs and material haul-off requirements.
