Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Clear-To-Build

A formal go-ahead issued by a prime contractor or owner confirming all approvals, permits, and engineering are in place. Subcontractors should not mobilise crews or materials until this authorisation is received. Starting work without it can void contract protections and leave you liable for costs.

Related Terms

Production Shut-in

Industry

A temporary halt to oil or gas production at a well or facility, ordered by the operator. For subcontractors, this often means suspended work orders and delayed revenue until operations resume. Standby rates and demobilisation terms in your contract become critical during a shut-in.

Utility Relocation

Industry

The process of moving existing underground or overhead utilities — such as gas lines, water mains, or electrical conduits — to accommodate new construction or pipeline work. Subcontractors are often hired specifically for this scope, which requires utility locates and coordination with municipal or utility owners. Delays in relocation can directly impact your crew's mobilisation schedule and project milestones.

LNTP (Limited Notice To Proceed)

Industry

A partial greenlight from a client authorising subcontractors to begin limited, specific work before the full contract is executed. It typically covers early mobilisation, procurement, or site prep activities only. Scope and spending are strictly capped, so track your costs carefully to avoid unauthorised overruns.

MCF (Thousand Cubic Feet)

Industry

Standard unit for measuring natural gas volumes, equal to 1,000 cubic feet. Subcontractors use MCF to interpret production targets, scope work, and align service pricing on gas well projects. Billing rates and throughput bonuses are often tied directly to MCF volumes.

Paying Quantities

Industry

A legal threshold where a well produces enough oil or gas to justify continued operations and generate profit. For subcontractors, it determines whether a site stays active and whether ongoing service contracts remain in force. Loss of paying quantities can trigger contract suspension or early termination clauses.

Gyroscopic Guidance

Industry

A downhole navigation system that uses gyroscopes to track drill bit position and direction without magnetic interference. Subcontractors use it in areas where magnetic tools fail, such as near casing or in high-latitude regions. Accurate wellbore placement reduces costly corrections and keeps projects on schedule.
