A preliminary document outlining the key commercial terms agreed between parties before a formal contract is finalised. For subcontractors, it signals serious intent but is not always legally binding. Avoid mobilising crews or purchasing materials based solely on an HoA.
Heads of Agreement (hoa)
Related Terms
Battery Tolling Agreement
IndustryA contract where a subcontractor operates a battery energy storage system on behalf of an asset owner, earning a fee without owning the asset. Common on remote sites and camps where third-party power management services are contracted out. Subcontractors are paid for capacity and availability, not energy consumed.
Service Company
IndustryA company that provides specialized services to oil and gas operators, such as drilling, completions, workover, transportation, or maintenance. Also called oilfield services (OFS).
Negative Gas Prices
IndustryOccurs when oversupply forces producers to pay buyers to take gas, signalling severe market stress. For subcontractors, this often triggers rapid project suspensions, deferred work orders, and delayed payments. Expect scope reductions and early contract terminations when prices turn negative.
Wastewater Injection
IndustryThe process of pumping produced water or other fluid waste deep into underground formations for disposal. Subcontractors operating injection pumps or wellbore equipment must meet strict provincial and federal disposal regulations. Work often requires specialised well integrity certifications and detailed fluid volume reporting.
Strait of Hormuz
IndustryA critical shipping chokepoint between Oman and Iran controlling roughly 20% of global oil flow. Disruptions here can spike material costs and delay equipment deliveries for subcontractors. Budget contingencies and procurement timelines should account for geopolitical risk in this corridor.
Predictive Maintenance
IndustryA maintenance approach that uses equipment data and monitoring to forecast failures before they occur. Subcontractors may be dispatched for targeted repairs based on sensor alerts rather than fixed schedules. This reduces emergency callouts and helps crews plan mobilisation more efficiently.
