Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Back-To-Back Well Program

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.

Related Terms

Interconnection Delay

Industry

A postponement caused by unfinished grid or pipeline tie-in work that prevents a facility from going live. For subcontractors, it often means demobilisation holds, scope gaps, or standby costs with no clear end date. Document all waiting time carefully to support delay claims or change orders.

CIP (Capital Improvement Program)

Industry

A planned cycle of major infrastructure upgrades or expansions at a facility, often releasing large volumes of subcontract work. For field service companies, CIPs signal sustained project pipelines worth pursuing long-term agreements for. Monitoring client CIP schedules helps subcontractors forecast workload and mobilise crews strategically.

TIC (Total Installed Cost)

Industry

The full cost of completing a scope of work, including labour, equipment, materials, and indirect expenses. Subcontractors use TIC to build accurate bids and avoid underpricing complex field installations. Owners and GCs often benchmark TIC when evaluating competing quotes.

Offshore Commissioning

Industry

The process of testing and activating offshore systems and equipment before handover to the operator. For subcontractors, this phase typically requires specialised certifications and offshore survival training. Mobilisation costs and remote logistics significantly affect bid pricing and crew planning.

Begin Actual Construction

Industry

The point when physical site work starts, triggering contract milestones, mobilisation schedules, and billing periods for subcontractors. It typically marks when crews, equipment, and materials must be on-site and ready. Delays to this date directly affect subcontractor cash flow and resource planning.

Caisson

Industry

A watertight steel or concrete structure used to support foundations in offshore or waterlogged environments. Subcontractors may be scoped to install, inspect, or perform maintenance work on caissons. Access and confined space protocols often apply.
