Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Ip Rate (initial Production Rate)

The 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.

Related Terms

Bladder Tank

Industry

A collapsible, flexible fluid storage container used on job sites to hold fuel, water, or chemicals. Subcontractors often mobilise them where permanent tanks aren't practical. They're common on remote oil and gas and construction sites.

PWHT (Post-weld Heat Treatment)

Industry

A controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.

Pipeline Tie-in

Industry

A pipeline tie-in is the physical connection of a new pipeline section to an existing live system. For subcontractors, tie-in work often requires hot-tap certified crews and strict isolation procedures. Scheduling is critical, as tie-ins typically involve planned shutdowns with tight production windows.

Triplex Mud Pump

Industry

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.

AFE (Authorization for Expenditure)

Industry

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

MWD (Measurement While Drilling)

Industry

A real-time data acquisition process used during directional drilling that transmits downhole measurements — such as wellbore trajectory, formation data, and tool orientation — to surface crews without interrupting operations. For subcontractors, MWD services represent a specialised scope of work requiring certified technicians and dedicated equipment, often billed as a separate line item on drilling contracts.
