A PMC is the company hired by an owner to oversee and manage an entire project on their behalf. As a subcontractor, the PMC is typically your primary point of contact for approvals, invoicing, and scope direction. They control schedule and budget, so understanding their reporting requirements is essential for getting paid on time.

Well stimulation refers to treatments like hydraulic fracturing or acid jobs that improve reservoir flow. Subcontractors often mobilise for short, intensive campaigns requiring specialised crews and equipment. Scope changes and standby time are common, so clear contract terms matter.

A coastal or estuary facility where bulk commodities like LNG or crude oil are loaded onto marine vessels for export. Water depth fluctuates with tides, affecting vessel scheduling and your crew's access windows. Subcontractors must plan shifts and equipment mobilisation around tide tables and vessel berthing schedules.

Drilling program that follows an initial discovery to confirm reservoir size and commercial viability. For subcontractors, it means short-term, high-intensity scopes between exploration and full development phases. Mobilisation windows can be tight and contract durations unpredictable.

A non-binding agreement outlining the intent to work together before a formal contract is signed. Subcontractors use MOUs to secure preferred vendor status or reserve capacity for upcoming projects. They carry no payment guarantee, so avoid mobilising resources based solely on an MOU.

Natural gas trapped in low-permeability rock formations that require hydraulic fracturing or horizontal drilling to extract. For subcontractors, tight gas projects typically involve intensive well stimulation work and longer mobilisation cycles. Expect higher equipment demands and specialised crew certifications on these sites.
