The evaluation of reservoir rock and fluid properties using well log data and core samples. Results determine whether a well is worth completing, directly affecting drilling programme scope and subcontractor workload. Field crews support this work through wireline logging, coring, and fluid sampling operations.

Subcontractor
IndustryA company hired by a general contractor or directly by an operator to perform a specific portion of work. Subcontractors often specialize in particular services or trades.
Greenfield
IndustryA project built from scratch on a previously undeveloped site, with no existing infrastructure. For subcontractors, this means longer mobilisation timelines and higher early-stage labour demand. Expect more scope changes and stronger opportunities for long-term contract work.
Artificial Lift
IndustryA system used to boost production from oil wells that lack sufficient natural pressure to bring fluids to surface. Common methods include rod pumps, ESPs (Electric Submersible Pumps), and gas lift. Subcontractors are often mobilised to install, service, or troubleshoot these systems throughout a well's producing life.
Exploration Well
IndustryA well drilled in an unproven or lightly tested area to determine whether hydrocarbons are present, often representing shorter-term, high-mobilisation contracts for subcontractors with less predictable follow-on work than development drilling programmes.
BPD (Barrels Per Day)
IndustryA measure of a well's or facility's daily oil output. Higher BPD typically means greater activity levels, more crews on site, and increased service demand. Subcontractors often see scope and call-out frequency tied directly to a client's BPD targets.
Spot Work
IndustryShort-term, unplanned jobs awarded without a long-term contract, typically filled on short notice. Subcontractors are engaged for a single scope or site visit at a negotiated day rate. Common in shutdown, turnaround, and emergency maintenance situations.
