Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Bill of Materials

A BOM (Bill of Materials) is an itemised list of all parts, materials, and components needed to complete a field job. Subcontractors use it to price work accurately and track material costs against their scope. It also supports invoicing and helps avoid disputes over what was supplied on site.

Related Terms

BIM (Building Information Modelling)

Industry

A shared 3D digital model of a construction project that contains structural, mechanical, and site data. Subcontractors use it to coordinate work sequences, avoid clashes with other trades, and verify installation specs before mobilising. Access to the BIM model is often required before entering a worksite.

Guidance Engineer

Industry

A specialist who oversees directional drilling operations, ensuring wellbores are steered accurately to target zones. Subcontractors often supply these roles to operators on a contract basis. They work closely with MWD (Measurement While Drilling) technicians on site.

CAPEX (Capital Expenditure)

Industry

Funds an operator spends on major assets like wells, pipelines, or facilities. High CAPEX cycles mean more subcontract opportunities for field crews and equipment providers. Low CAPEX periods often signal slower work volumes and tighter bid competition.

Gathering Infrastructure

Industry

The network of pipelines, compressors, and processing facilities that collect hydrocarbons from wellheads and move them to processing or transmission points. For subcontractors, it represents a major source of construction, maintenance, and inspection work. Projects often run concurrently with drilling programmes, creating tight scheduling demands.

Dewatered Sand

Industry

Sand or granular material that has had excess water removed, typically through drainage or mechanical separation on site. Subcontractors handling dewatered sand face stricter disposal and hauling requirements than wet slurry. Confirm moisture content specs before mobilising equipment or quoting removal work.

FID (Final Investment Decision)

Industry

The point when a project owner formally approves funding and commits to proceeding with a major project. For subcontractors, FID is the trigger that converts preliminary work into confirmed scopes and purchase orders. Mobilisation planning, crew hiring, and equipment sourcing typically begin after FID is announced.
