An industry classification covering subcontractors who provide services to upstream oil and gas producers without extracting resources themselves. This includes well servicing, site prep, equipment rental, and pipeline support. Most field service companies in oil and gas fall under this category for tax and regulatory purposes.
Support Activities for Oil and Gas Operations
Related Terms
Capital Program
IndustryA planned set of major construction or infrastructure projects approved by an owner or operator for a defined period. For subcontractors, it signals sustained work volumes and long-term contracting opportunities. Aligning your capacity with a client's capital program can anchor your pipeline for months or years.
Minimum Wall Thickness
IndustryThe lowest acceptable pipe or vessel wall thickness before the component must be repaired or replaced. Subcontractors performing inspection or maintenance work must verify measurements meet this threshold. Falling below it triggers mandatory remediation and can halt operations until resolved.
PAC (Polyanionic Cellulose)
IndustryA water-soluble polymer additive used in drilling fluids to control fluid loss and stabilise boreholes. Subcontractors handling mud systems must store and mix PAC carefully, as improper use affects drilling performance. It is commonly specified in drilling programmes, so field crews should follow the mud engineer's exact dosage instructions.
Gas-Directed Rig Count
IndustryThe number of drilling rigs actively targeting natural gas formations at a given time. A rising gas-directed rig count signals increased demand for field services and subcontractor crews. Tracking this metric helps you anticipate work volumes and mobilisation timelines in gas-heavy basins.
Conduit Installation
IndustryThe process of routing and securing protective tubing or piping to house electrical wiring on job sites. Subcontractors are typically scoped for this work during facility builds, plant turnarounds, or infrastructure upgrades. Accurate material take-offs and labour estimates are critical to pricing this work profitably.
Mwh (megawatt-Hour)
IndustryA unit measuring one megawatt of electrical power consumed or produced over one hour. Subcontractors encounter MWh when billing for generator rentals, temporary power supply, or energy-intensive equipment on remote sites. It also appears in green energy projects where field crews install or service solar, wind, or battery storage systems.
