Industry Glossary Term

Directional Services

Specialised drilling support that steers a wellbore along a planned trajectory rather than straight down. Subcontractors provide MWD (Measurement While Drilling) tools, mud motors, and on-site directional drillers. These crews are typically mobilised on a per-well basis under dedicated service contracts.

Related Terms

Henry Hub

Industry

A natural gas pricing benchmark set at a Louisiana pipeline hub, widely used in North American supply contracts. When Henry Hub prices rise, upstream activity increases and subcontractor demand typically follows. Monitoring this index helps field service companies anticipate project volumes and negotiate rates.

Shaker Screen

Industry

A mesh filter used in drilling operations to separate rock cuttings and solids from drilling fluid (mud). Subcontractors handling fluid management or solids control equipment must monitor screen condition closely. Worn or damaged screens reduce efficiency and can trigger costly downtime charges.

Crane Mats

Industry

Large interlocked timber or composite panels placed under crane outriggers to distribute load on soft or unstable ground. Subcontractors often supply, transport, and install them as part of site prep scopes. Rental and mobilisation costs should be clearly itemised in your quote.

Well Lifecycle

Industry

The full sequence of a well's existence, from drilling and completion through production and eventual abandonment. For subcontractors, each phase represents distinct scopes of work, crew requirements, and contract opportunities. Understanding the lifecycle helps you anticipate project transitions and position for follow-on work.

Cm/gc (construction Manager/general Contractor)

Industry

A delivery model where one firm handles both project management and general contracting. For subcontractors, this means a single point of contact manages your scope, schedule, and contract. Expect tighter coordination requirements and change order oversight from the CM/GC.

E&I (Electrical and Instrumentation)

Industry

A trade discipline covering the installation, maintenance, and commissioning of electrical systems and process instrumentation on industrial sites. Subcontractors in this scope typically hold specialised certifications and work across upstream, midstream, and construction projects. E&I scopes are commonly tendered separately from mechanical or civil work.
