Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Task Order

A formal document issued under a master contract that authorises a specific scope of work, timeline, and budget. Subcontractors use task orders to mobilise crews and bill for individual job phases. Each task order typically carries its own number for invoicing and cost-tracking purposes.

Related Terms

Surface Milling

Industry

A machining process that removes material from a flat surface to restore or achieve precise tolerances on equipment components. Subcontractors are often mobilised to perform surface milling on wellheads, flanges, or structural steel on-site. Proper equipment certifications and dimensional records are typically required for handover documentation.

HDD (Horizontal Directional Drilling)

Industry

A trenchless method used to install pipelines, conduits, or cables beneath obstacles like roads, rivers, or existing infrastructure. Subcontractors are typically engaged for the drill crew, mud mixing, and equipment operation. Scopes are highly specialised and often require certified operators and dedicated HDD spreads.

Miocene Formation

Industry

A geological layer dating from roughly 5 to 23 million years ago, often targeted for oil and gas production. Subcontractors may encounter specific drilling, completion, or well-servicing scopes tied to Miocene reservoirs. Formation characteristics influence equipment selection, mud programmes, and crew specialisation requirements.

Dual-Class Share Structure

Industry

A corporate ownership arrangement where founders or executives hold shares with greater voting power than ordinary investors. For subcontractors, this means a client company's leadership can make major operational decisions without shareholder approval. Expect stable long-term contracts but limited outside pressure to change payment terms or procurement practices.

Multi-Well Pad

Industry

A single surface location where multiple wells are drilled and completed in sequence. For subcontractors, this means extended site presence, higher mobilisation value, and repeated service cycles from one location. Scheduling and crew continuity are critical to securing ongoing work across the pad.

IET (Industrial & Energy Technology)

Industry

A broad sector covering technical services and equipment used in oil & gas, power, and industrial facilities. Subcontractors in this space typically provide specialised labour, maintenance, and installation work. Contracts often require trades certification and site-specific safety compliance.
