Industry Glossary Term

Membrane Separation

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.

Related Terms

MTPA (Million Tonnes Per Annum)

Industry

A measure of a facility's annual production or processing capacity, expressed in millions of tonnes. Larger MTPA ratings typically signal longer project durations and higher subcontractor labour demand. Knowing a site's MTPA helps field service companies anticipate scope size and resource requirements.

Highway Trust Fund

Industry

A U.S. federal fund that finances highway and infrastructure construction projects. Subcontractors bidding on federally funded road or infrastructure work must meet strict compliance and wage requirements tied to this funding. Budget cycles and congressional approvals directly affect project timelines and payment schedules.

WTI (West Texas Intermediate)

Industry

A global benchmark crude oil price used to gauge market health and operator spending confidence. When WTI prices drop, clients often freeze or cut field service contracts and budgets. Rising WTI typically signals more work and stronger mobilisation activity for subcontractors.

EIA (Energy Information Administration)

Industry

A U.S. federal agency that publishes energy data, forecasts, and market reports. Subcontractors use EIA reports to track oil and gas price trends and anticipate shifts in project demand. Monitoring EIA data helps field service companies time bids and resource planning.

Lower 48

Industry

Refers to the contiguous United States, excluding Alaska and Hawaii. For subcontractors, it defines a common work jurisdiction with distinct regulatory, tax, and labour rules from Canadian or Alaskan operations. Mobilisation costs and compliance requirements differ significantly when crews cross into or out of this region.

Tubulars

Industry

Steel pipes used in drilling and well construction, including casing, tubing, and drill pipe. Subcontractors handling tubulars must follow strict inspection and handling procedures. Damage during your scope can result in costly liability claims.
