A geophysical mapping operation that uses sound waves to image underground formations before drilling begins. Subcontractors are hired to deploy geophones, vibroseis trucks, or marine streamers across large survey grids. Work is often remote and time-sensitive, with crews mobilising quickly once permits are secured.

Sand Management
IndustryThe process of controlling, monitoring, and removing sand produced alongside oil and gas to protect wellbore equipment and surface facilities. Subcontractors may be hired to install sand screens, separators, or erosion monitoring systems. Poor sand management accelerates equipment wear and increases maintenance callouts.
PSI (Pounds Per Square Inch)
IndustryA unit measuring pressure in pipelines, hydraulic systems, and wellhead equipment. Subcontractors must verify PSI ratings when selecting tools, hoses, and fittings for safe operation. Exceeding rated PSI limits can trigger equipment failure, injuries, and liability.
MCF (Thousand Cubic Feet)
IndustryStandard unit for measuring natural gas volumes, equal to 1,000 cubic feet. Subcontractors use MCF to interpret production targets, scope work, and align service pricing on gas well projects. Billing rates and throughput bonuses are often tied directly to MCF volumes.
Prospective Interval
IndustryA rock formation believed to contain oil or gas, targeted for drilling or evaluation. Subcontractors are often mobilised to support exploration work within these zones. Scope and duration of field service contracts may depend on how many prospective intervals a well will test.
SPP (Southwest Power Pool)
IndustryA regional transmission organisation managing the electrical grid across 14 U.S. states. Subcontractors working on power infrastructure, grid upgrades, or energy facilities in this region must align with SPP reliability standards. Understanding SPP's operating rules helps field crews coordinate outages and energisation schedules.
Geothermal Brine
IndustryHighly mineralised, hot saltwater extracted from underground geothermal reservoirs during energy production. Subcontractors handling it must follow strict corrosion control and PPE protocols. Disposal and handling are heavily regulated due to its chemical content.
