Heads of Agreement (hoa)

Refers to large capital projects with lead times and development phases spanning several years. For subcontractors, long-cycle work offers extended contract visibility but requires patience on mobilisation and payment timelines. Budget cycles and scope changes are common over the project life.

A project delivery method where design and construction phases overlap, with the owner and contractor collaborating before scope is fully defined. Subcontractors are often brought on early, meaning scope, pricing, and schedules can shift as design matures. Contracts may be cost-reimbursable at first, then convert to fixed-price once scope is confirmed.

A designated location where materials, parts, or equipment are staged for quick deployment to active job sites. Subcontractors often draw inventory from a client's stockpoint rather than sourcing independently. Knowing stockpoint locations reduces mobilisation delays and simplifies cost tracking.

A development area targeting light liquid hydrocarbons that separate from natural gas at surface. These plays often require specialised separator handling and fluid management equipment. Subcontractors can expect steady demand for well servicing, trucking, and processing facility work.

A scope-of-work term covering all field service activities from the producing wellhead to the point of water disposal or treatment. For subcontractors, it defines mobilisation boundaries and billable work limits on produced-water handling projects. Knowing this scope prevents disputes over who owns each task segment.

HMA (Hot Mix Asphalt) is a paving material combining aggregate and bitumen, mixed and applied at high temperatures. Subcontractors must coordinate tight delivery windows, as HMA cools quickly and becomes unusable. Proper equipment and certified operators are typically required on job sites.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.

Rig counts are the earliest signal of where field service work is heading. Learn how to read drilling activity trends, anticipate demand shifts, and position your crew before the phone stops ringing.
