Loose, weakly bonded subsurface material — such as sand, gravel, or soft clay — that hasn't hardened into solid rock. These formations create unstable borehole conditions, increasing risk of collapse and equipment loss. Subcontractors drilling or excavating in these zones often face additional scope, specialised equipment requirements, and potential cost disputes.
Unconsolidated Formation
Related Terms
Shaker Screens
IndustryMesh filters mounted on shale shakers that separate drill cuttings from drilling fluid on the rig. Subcontractors handling fluid management or solids control must track screen condition and swap them regularly. Damaged or plugged screens slow operations and can trigger downtime charges against your crew.
Spud Date
IndustryThe date when drilling begins on a new well. Marks the start of drilling operations.
Radial Conveyor
IndustryA belt conveyor mounted on a wheeled chassis that pivots in an arc to distribute bulk materials across a wide stockpile area. Subcontractors use them on aggregate, sand, and gravel sites to manage material placement without constant repositioning. They reduce manual labour and speed up site operations significantly.
CPF (Central Processing Facility)
IndustryA fixed surface facility where oil, gas, and water from multiple wells are separated, treated, and prepared for transport or sale. For subcontractors, a CPF is often a long-term, high-activity work site requiring trades, maintenance, and operations crews. Scope can include initial construction, commissioning, turnarounds, and ongoing maintenance contracts.
Phased Array Ut (phased Array Ultrasonic Testing)
IndustryAn advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds and materials for defects. It replaces traditional radiography on many pipeline and pressure vessel jobs. Subcontractors offering PAUT services often command higher rates and qualify for more specialised scopes.
Shaker Screen
IndustryA mesh filter used in drilling operations to separate rock cuttings and solids from drilling fluid (mud). Subcontractors handling fluid management or solids control equipment must monitor screen condition closely. Worn or damaged screens reduce efficiency and can trigger costly downtime charges.
