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

Ngl (natural Gas Liquid) Fractionator

Industry

A processing facility that separates mixed natural gas liquids into individual products like propane, butane, and ethane. Subcontractors often work these sites for maintenance, turnarounds, and equipment servicing. Fractionators operate continuously, so field crews should expect shift-based schedules and strict hot-work permitting.

Well Program

Industry

A technical document outlining the planned scope, procedures, and specifications for drilling or completing a well. Subcontractors use it to understand required services, equipment, and sequencing before mobilising. It directly affects how you scope work and price your bid.

BOE (Barrel of Oil Equivalent)

Industry

A standardised unit of energy measurement that converts different types of oil and gas production into equivalent barrels of crude oil, used by operators to report total production volumes when determining project scope and service requirements for subcontractors.

Surface Miner

Industry

A large self-propelled machine that cuts, crushes, and loads material in a single pass without blasting. Subcontractors operating surface miners must hold specialised equipment certifications and follow strict site safety protocols. Common in oil sands and open-pit construction projects across Western Canada.

MWD (Measurement While Drilling)

Industry

A real-time data acquisition process used during directional drilling that transmits downhole measurements — such as wellbore trajectory, formation data, and tool orientation — to surface crews without interrupting operations. For subcontractors, MWD services represent a specialised scope of work requiring certified technicians and dedicated equipment, often billed as a separate line item on drilling contracts.

Spud Date

Industry

The date when drilling begins on a new well. Marks the start of drilling operations.
