On-location support work performed at an active drill site, including safety watch, equipment operation, and logistics. Subcontractors are typically mobilised on short notice and paid on a day-rate basis. Scope can shift quickly, so clear change-order processes are essential.
Wellsite Services
Related Terms
Deepwater Export Terminal
IndustryAn offshore facility in deep water where oil or gas is transferred from production infrastructure to tankers or pipelines for transport. For subcontractors, these sites require specialised marine certifications and offshore safety training. Mobilisation costs are high, so confirm day-rate structures and expense recovery terms before committing crews.
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.
Stimulation
IndustryWell stimulation refers to treatments like hydraulic fracturing or acid jobs that improve reservoir flow. Subcontractors often mobilise for short, intensive campaigns requiring specialised crews and equipment. Scope changes and standby time are common, so clear contract terms matter.
Run/repair/replace
IndustryA decision-making framework used to evaluate whether aging or damaged equipment should continue operating, be repaired, or be swapped out entirely. Subcontractors are often called in to assess assets and execute whichever option the client authorises. Understanding this process helps field crews scope work accurately and avoid scope creep on site.
Carbon Dioxide Treater
IndustryA vessel or system used on oil and gas sites to remove CO2 (Carbon Dioxide) from produced gas or water streams. Subcontractors are often hired to install, service, and inspect these units. Proper handling requires H2S and pressure safety training.
Pylon
IndustryA tall structural tower used to support overhead power lines, pipelines, or signage on job sites. Subcontractors may work near pylons during civil, electrical, or pipeline installation scopes. Always verify exclusion zones before mobilising equipment.
