A 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.
PSI (Pounds Per Square Inch)

TEU (Twenty-foot Equivalent Unit)
IndustryA standard shipping container measurement used to calculate freight capacity and logistics costs on large projects. One TEU equals one standard 20-foot container. Subcontractors mobilising equipment or materials to remote sites often quote and invoice freight in TEUs.
Field Ticket
IndustryA document created in the field that records work performed, equipment used, materials consumed, and time spent. Field tickets are the basis for invoicing and must typically be approved by the customer before payment.
Reservoir Characterization
IndustryThe process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.
Mmcf/d (million Cubic Feet Per Day)
IndustryA measurement of natural gas production or flow volume, used to describe the output capacity of a well, pipeline, or facility. Subcontractors use this figure to gauge job scale, equipment sizing, and crew requirements. Higher MMcf/d ratings typically signal larger scopes of work and longer contract durations.
Shale Gas
IndustryNatural gas extracted from shale rock formations using hydraulic fracturing and horizontal drilling. For subcontractors, shale gas projects drive high demand for frac crews, equipment operators, and site services. Work is often concentrated in multi-well pad campaigns, creating steady but intense mobilisation cycles.
MOU (Memorandum of Understanding)
IndustryA non-binding agreement outlining the intent to work together before a formal contract is signed. Subcontractors use MOUs to secure preferred vendor status or reserve capacity for upcoming projects. They carry no payment guarantee, so avoid mobilising resources based solely on an MOU.
