Daily oil & gas and construction news for subcontractors

Industry Glossary Term

Inversion (pipe Lining)

A trenchless pipe rehabilitation method where a resin-saturated liner is turned inside-out into an existing pipe using water or air pressure. The liner cures in place, forming a new pipe within the old one. Subcontractors are typically scoped for setup, inversion equipment operation, and post-cure inspection.

Related Terms

PWHT (Post-weld Heat Treatment)

Industry

A controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.

VLCC (Very Large Crude Carrier)

Industry

A massive oil tanker capable of carrying up to two million barrels of crude. Subcontractors providing marine maintenance, inspection, or coating services may be mobilised to service VLCCs at port or in dry dock. These vessels require specialised certifications and safety compliance for anyone working aboard.

Capital Maintenance Agreement

Industry

A long-term contract where a subcontractor provides scheduled upkeep and repairs on a client's major assets or facilities. Work scopes, pricing, and mobilisation terms are typically locked in advance. These agreements offer subcontractors predictable revenue but may limit flexibility to take on other work.

2c Resources

Industry

The middle estimate of contingent petroleum resources that are discovered but not yet approved for development. For subcontractors, 2C resource announcements often signal future project opportunities that are not yet fully funded. Bid opportunities tied to 2C resources carry higher uncertainty and may shift significantly before contracts are awarded.

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.

Co2 Storage (carbon Dioxide Storage)

Industry

The permanent underground injection of captured CO2 into geological formations like depleted reservoirs or saline aquifers. Subcontractors may support well preparation, pipeline installation, monitoring equipment, and injection operations. Demand for specialised field crews is growing as carbon capture projects expand across Canada.
