Industry Glossary Term

LWD (Logging While Drilling)

A drilling technique that collects formation data in real time as the bit advances. Subcontractors providing LWD services operate specialised downhole tools that transmit data to surface during the drill run. Mobilisation windows are tight, so crews and equipment must be ready on short notice.

Related Terms

Lateral Length

Industry

The horizontal distance drilled from the kickoff point to the end of a wellbore, typically measured in metres. Longer laterals mean more stages, more equipment, and extended crew time on location. Subcontractors should factor lateral length into job costing and resource planning.

Commissioning

Industry

The phase where completed systems and equipment are tested, verified, and handed over to the client as fully operational. For subcontractors, it often means intensive punch-list work, inspections, and sign-offs before demobilisation. Scope creep is common during this phase, so track all additional hours carefully.

Bore

Industry

A drilled or excavated hole through soil, rock, or existing structure. Subcontractors are often scoped to complete a specified number of bores per shift. Bore diameter and depth directly affect equipment selection and crew sizing.

Service Company

Industry

A company that provides specialized services to oil and gas operators, such as drilling, completions, workover, transportation, or maintenance. Also called oilfield services (OFS).

Geosteering

Industry

The real-time technique of guiding a drill bit through a target formation using geological data. Subcontractors supporting drilling operations may be called in on short notice as geosteering decisions change well paths. Expect scope adjustments and rapid crew or equipment mobilisation when geosteering is active.

Feedstock

Industry

Raw material fed into a processing facility, such as crude oil, bitumen, or natural gas. Subcontractors often support feedstock handling through pipeline work, tank maintenance, and material transfer operations.
