Acreage Position

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.

A water-soluble polymer additive used in drilling fluids to control fluid loss and stabilise boreholes. Subcontractors handling mud systems must store and mix PAC carefully, as improper use affects drilling performance. It is commonly specified in drilling programmes, so field crews should follow the mud engineer's exact dosage instructions.

A structural tower erected over a mine shaft to support hoisting equipment and guide cables. Subcontractors working near headframes must coordinate lifts and personnel movement carefully. Access restrictions and load limits are strictly enforced on-site.

An unmanned, tethered underwater robot used to inspect, survey, or perform work on subsea pipelines, wellheads, and structures — subcontractors providing ROV services typically require specialised operators and vessels, and should account for mobilisation costs and standby rates when bidding these scopes.

The middle estimate of contingent petroleum resources that are discovered but not yet approved for development. For subcontractors, 2C resource announcements often signal future project opportunities that are not yet fully funded. Bid opportunities tied to 2C resources carry higher uncertainty and may shift significantly before contracts are awarded.

When two companies combine or one buys another, reshuffling vendor lists and contract structures. Subcontractors may face renegotiated rates, new prequalification requirements, or lost preferred-supplier status. Monitor client M&A activity closely — approved contractor rosters often get cut during integration.
