Industry Glossary Term

Completions

The phase of oil and gas well development after drilling is finished, encompassing the work required to prepare a well for production — including perforating, fracturing, and installing wellhead equipment. For subcontractors, completions represent a concentrated burst of high-demand field work where specialised crews, equipment, and services are mobilised under tight timelines.

Related Terms

ERCOT (Electric Reliability Council of Texas)

Industry

The grid operator managing Texas's independent power network, separate from national grids. Subcontractors working Texas energy projects must understand ERCOT rules govern power availability and outages. Grid instability events like Winter Storm Uri directly impact field site operations and project timelines.

AFE (Authorization for Expenditure)

Industry

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

SWD (Saltwater Disposal)

Industry

The process of injecting produced water from oil and gas operations into approved underground formations. Subcontractors may operate or service SWD facilities, including pump maintenance, wellbore work, and fluid hauling. Understanding SWD volumes and schedules helps crews plan trucking, pit management, and injection equipment needs.

ERCIP (Energy Resilience and Conservation Investment Program)

Industry

A U.S. Department of Defense funding programme for energy resilience projects on military installations. Subcontractors often access this work through prime contractors on federally funded construction or energy retrofit scopes. Understanding ERCIP helps field service firms identify bid opportunities in government energy infrastructure.

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.

Subsea Production System

Industry

A network of underwater equipment — including wellheads, manifolds, flowlines, and control systems — installed on the seabed to extract and transport oil or gas to a surface facility, representing a specialised scope of subsea installation, inspection, and maintenance work that subcontractors must hold specific certifications and equipment to perform. For field service companies, contracts in this space typically involve saturation diving support, remotely operated vehicle (ROV) operations, or subsea engineering services under strict offshore safety and quality regimes.
