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.

Leasehold
IndustryLand or mineral rights an operator has legally secured through a lease agreement with the landowner or Crown. Subcontractors typically work within leasehold boundaries, so access, permitting, and site rules are set by the operator holding the lease. Understanding leasehold limits helps crews avoid trespassing on adjacent unlicensed areas.
Legacy Well
IndustryAn older well built to outdated standards that may require specialised remediation, abandonment, or workover services. Subcontractors should expect non-standard equipment configurations and additional compliance requirements. Scope creep and unforeseen costs are common on legacy well projects.
Undeveloped Inventory
IndustryApproved but undrilled well locations or untapped reserves an operator plans to develop in future phases. For subcontractors, it signals upcoming work pipelines and potential long-term contract opportunities. Tracking an operator's undeveloped inventory helps you anticipate mobilisation timelines and resource planning.
Cryogenic Processing
IndustryA method of separating natural gas into valuable components by cooling it to extremely low temperatures. Subcontractors may be required to hold specialised certifications and use cryogenic-rated equipment on these sites. Strict handling protocols apply, as cryogenic materials pose serious safety risks to field crews.
Royalty Rate
IndustryThe percentage of resource revenue an operator pays to the Crown or landowner before profits are calculated. High royalty rates can reduce operator budgets, directly affecting subcontractor hiring and field service spending. Understanding local royalty structures helps subcontractors anticipate project volumes and client cash flow.
Battery
IndustryA centralised surface facility where oil and gas from multiple wells is gathered, measured, and processed. Subcontractors frequently mobilise to battery sites for maintenance, instrumentation, and civil work. Knowing the battery layout helps crews plan access, logistics, and safe work zones.
