Co2 Storage (carbon Dioxide Storage)

A section of pipeline, conduit, or cable routed beneath or across a river, creek, or other body of water. Crossings typically use methods like horizontal directional drilling (HDD) or open-cut trenching. Subcontractors must meet strict environmental permits and inspection requirements before and after installation.

The process of injecting produced water from oil and gas operations into approved underground formations. Subcontractors may operate or service SWD facilities, including pump maintenance, wellbore work, and fluid hauling. Understanding SWD volumes and schedules helps crews plan trucking, pit management, and injection equipment needs.

A secondary compressor used to increase gas pressure in pipelines or processing systems when inlet pressure is too low. Subcontractors are often hired to install, operate, or maintain these units on short-term field assignments. Rental and service contracts for booster compressors are common in late-life field operations.

A weekly tally of active drilling rigs operating across a region, published by companies like Baker Hughes. Subcontractors use it to gauge market demand and anticipate work volumes. A rising count typically signals increased opportunities for drilling-related field services.

Drilling rigs specifically configured to drill natural gas wells, requiring crews and equipment rated for high-pressure gas formations. For subcontractors, gas rigs often demand specialised certifications and H2S training. Work volumes typically follow natural gas commodity prices and seasonal heating demand.

A stage in a project where workflow bottlenecks, delaying downstream tasks and crew productivity. For subcontractors, chokepoints often occur at inspection holds, permit approvals, or material deliveries. Identifying them early helps protect schedule and avoid costly standby time.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
