Industry Glossary Term

Triplex Mud Pump

A three-cylinder reciprocating pump used on drilling rigs to circulate drilling fluid down the wellbore. Subcontractors are often hired to operate, maintain, or repair these high-pressure units. Reliable pump performance is critical — downtime directly impacts rig schedules and your contract standing.

Related Terms

Horizontal Well

Industry

A 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.

2c Resources

Industry

The middle estimate of contingent petroleum resources that are discovered but not yet approved for development. For subcontractors, 2C resource announcements often signal future project opportunities that are not yet fully funded. Bid opportunities tied to 2C resources carry higher uncertainty and may shift significantly before contracts are awarded.

Baseload Energy

Industry

The minimum level of power demand that a facility or site requires continuously, around the clock. For subcontractors, it determines whether remote worksites need dedicated generators or grid connections. Stable baseload requirements help crews plan equipment fuel consumption and maintenance schedules.

Production Hookup

Industry

The final phase of connecting a well or facility to live production infrastructure, including pipelines, separators, and metering equipment. For subcontractors, it typically means intensive, time-sensitive scope with strict sequencing requirements. Delays can trigger penalties, making accurate scheduling and crew readiness critical.

FID (Final Investment Decision)

Industry

The point when a project owner formally approves funding and commits to proceeding with a major project. For subcontractors, FID is the trigger that converts preliminary work into confirmed scopes and purchase orders. Mobilisation planning, crew hiring, and equipment sourcing typically begin after FID is announced.

Cold Milling

Industry

A surface removal process where a rotating drum grinds down asphalt or concrete without heat. Subcontractors use it for road rehabilitation, pad preparation, and surface levelling on well sites or construction projects. Reclaimed material is often reused, reducing disposal costs.
