The process of safely shutting down and dismantling oil and gas infrastructure at end-of-life. For subcontractors, it generates significant work in removal, remediation, and site restoration. Scopes often include demolition, equipment salvage, and regulatory closeout tasks.
Decommissioning
Related Terms
Horizontal Well
IndustryA well that is drilled vertically to a certain depth then curved to run horizontally through a target formation, requiring subcontractors to mobilise specialised equipment and crews for extended-reach drilling, completions, and stimulation work that typically involves more complex logistics and longer on-site durations than conventional vertical wells.
Ip Rate (initial Production Rate)
IndustryThe IP Rate measures a well's output immediately after it comes online, typically in barrels or mcf per day. Operators use it to assess well performance, which directly affects how quickly field service contracts ramp up or wind down. A strong IP Rate often signals sustained work volume for subcontractors on site.
Acreage Position
IndustryThe total land or mineral rights an operator holds for exploration or production. A large acreage position often signals sustained work programmes and long-term subcontractor demand. It helps field service companies forecast pipeline opportunities in a region.
Life Extension
IndustryA formal process that prolongs the operational life of ageing assets beyond their original design lifespan. For subcontractors, it often means increased inspection, repair, and maintenance scopes. Expect stricter compliance requirements and potential for longer-term service contracts.
Minimum Work Program
IndustryA contractually obligated set of activities and expenditures an operator must complete within a set timeframe, typically tied to a licence or lease agreement; for subcontractors, this creates predictable scopes of work and mobilisation opportunities as operators must execute these commitments or risk losing their rights to the asset.
Rotary Rig Count
IndustryA 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.
