Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Feedgas

Raw natural gas supplied to a processing plant or facility for treatment and conditioning. Feedgas volumes and composition directly affect how long subcontractors are mobilised on-site. Changes to feedgas quality can trigger scope adjustments and additional service orders.

Asset Integrity

Industry

The ongoing process of ensuring equipment and structures perform their intended function safely and efficiently. For subcontractors, it drives demand for inspection, maintenance, and repair scopes across the project lifecycle. Clients often mandate documented asset integrity programmes before awarding field service contracts.

Back-To-Back Well Program

Industry

A drilling schedule where wells are spaced consecutively with minimal downtime between completions. For subcontractors, it means sustained mobilisation of crews and equipment across multiple well sites. Expect extended contract durations but also compressed turnaround times between locations.

Upstream Tie-in

Industry

A connection point where new pipeline or equipment is integrated into an existing live system closer to the wellhead or source. For subcontractors, this work typically requires strict hot-work permits and precise scheduling around production shutdowns. Delays at tie-in points directly impact your crew's standby time and invoice milestones.

Field Gathering Lines

Industry

Pipelines that collect oil, gas, or water from individual wellheads and route it to a central processing facility. Subcontractors frequently work on installation, inspection, and maintenance of these lines. Knowing the layout is essential for safe excavation and tie-in work.

Shallow-Water

Industry

Offshore operating zones typically under 500 feet of water depth. For subcontractors, these sites use jack-up rigs and barges rather than deepwater vessels. Crew access, equipment requirements, and mobilisation costs differ significantly from deepwater scopes.

Npv10 (net Present Value At 10% Discount Rate)

Industry

A method operators use to value oil and gas reserves by discounting future cash flows at 10% annually. Higher NPV10 signals a healthier client who can fund long-term projects and honour contracts. Subcontractors can use it to gauge whether a prospect client's asset base justifies pursuing work with them.
