Human-caused ground tremors triggered by oilfield operations like hydraulic fracturing or wastewater disposal. Regulators may issue stop-work orders, directly halting your field operations. Subcontractors should track local seismic thresholds, as exceeding them can suspend permits and delay project timelines.
Induced Seismicity
Related Terms
Methane Emissions Inventory
ComplianceA documented record of all methane releases from equipment and operations on a worksite. Subcontractors may be required to contribute data or maintain their own inventory to meet operator or regulatory reporting obligations. Accurate records help avoid penalties and support contract compliance.
Well Barrier
ComplianceA physical or mechanical system that prevents uncontrolled flow of fluids from a wellbore. Subcontractors working on or near wells must verify barriers are in place before starting work. Barrier failures can trigger stop-work obligations and regulatory reporting requirements.
Acclimatization
ComplianceThe process of allowing workers to safely adjust to extreme heat, cold, or altitude before full-duty deployment. Most worksites and safety regulations require a structured acclimatization period for new or returning crew. Subcontractors must factor this non-productive time into scheduling and labour costs.
Nepa (national Environmental Policy Act) Review
ComplianceA U.S. federal environmental assessment required before major project approvals on public lands. Subcontractors may face work delays or scope changes while reviews are completed. Mobilisation schedules should account for potential NEPA-related hold periods.
High-Energy Hazard
ComplianceAny source of stored or released energy that can cause serious injury or death, such as pressurised systems, suspended loads, or live electrical equipment. Subcontractors must identify these hazards before starting work and follow site-specific isolation procedures. Failure to control high-energy hazards is a leading cause of fatalities in oil and gas and construction environments.
JHA (Job Hazard Analysis)
ComplianceA written document identifying hazards and controls for a specific task before work begins. Subcontractors are typically required to complete and submit JHAs to the prime contractor or site owner. Failure to have a compliant JHA on site can result in work stoppages or disqualification from bidding.
