A filtration process that uses semi-permeable membranes to separate gases or liquids by molecular size or pressure. Common in natural gas processing and produced water treatment on field sites. Subcontractors may install, inspect, or maintain membrane units as part of facility service scopes.
Membrane Separation
Related Terms
Transmission Infrastructure
IndustryLarge-scale pipelines, compressor stations, and related facilities that move oil, gas, or power across long distances. Subcontractors are frequently mobilised for construction, inspection, and maintenance work on these assets. Scopes can be extensive, requiring multi-trade crews and strict regulatory compliance.
Multi-Well Pad
IndustryA single surface location where multiple wells are drilled and completed in sequence. For subcontractors, this means extended site presence, higher mobilisation value, and repeated service cycles from one location. Scheduling and crew continuity are critical to securing ongoing work across the pad.
Aggregates
IndustryCrushed stone, gravel, and sand used as base materials in construction and oil and gas site preparation. Subcontractors sourcing or hauling aggregates must account for material costs, transport, and site access conditions. Pricing and availability vary significantly by region and project remoteness.
Heavy Civil
IndustryLarge-scale infrastructure construction involving earthworks, bridges, roads, and foundations. Subcontractors in this sector typically supply specialised equipment, civil crews, or concrete services. Contracts are often high-value but require significant bonding and insurance capacity.
Resource Delineation
IndustryThe process of defining the boundaries and quantity of an oil, gas, or mineral deposit through appraisal drilling and testing. For subcontractors, it signals a sustained work programme requiring crew, equipment, and logistical planning. Delineation phases often drive multi-month contracts for drilling, completions, and field services.
Headframe
IndustryA structural tower erected over a mine shaft to support hoisting equipment and guide cables. Subcontractors working near headframes must coordinate lifts and personnel movement carefully. Access restrictions and load limits are strictly enforced on-site.
