Monitoring Well Installation & Testing
Any petrochemical storage site (not just service stations) which has an Underground Storage Tank must have Groundwater Monitoring Wells installed and monitored by 01 June 2011, as required by New South Wales EPA.
The person responsible for a UPSS (usually the owner/operator) is required to have in place per NSW EPA UPSS regulations:
- a system for detecting and monitoring leaks;
- groundwater monitoring wells at sensitive locations and a program to test them;
- an Environment Protection Plan for the facility;
- systems in place for record keeping, reporting of leaks and notifying the local council when a UPSS is decommissioned.
Borehole Inspections & Assessment
During borehole inspections and assessments, data can be collected by means of remote downhole tools such as imaging cameras, magnetic thickness tools, to determine the overall health of the borehole.
Our systematic borehole inspection and assessment approach enables Program Managers to manage and mitigate business risks. Our reports will prioritise their program for operational controls in terms of compliance, risk, environmental and health and safety regulatory requirements.
Borehole Decommissioning & Plugging
Plugging of abandoned water, oil and gas wells, and seismic holes is a viable option once we have completed our site inspection, prioritisation and risk ranking process.
- State Regulation: NSW Onshore Petroleum Exploration and Production Safety Requirements, August 1992; and NSW Water Management Act 2000 / Water Act 1912
- Environmental guidelines: Petroleum Licence conditions and Review of Environmental Factors, REF’s for each site under Part 5 of the petroleum act (when in the E&A phase);
- NSW Well Integrity Code of Practice (currently under review with government chief scientists);
- Industry best practice and guidelines, example: API Recommended Practice
Actual plugging of abandoned water, oil and gas wells, and seismic holes, protecting the subsurface aquifer and making the site safe.
Deteriorating boreholes or wells can get to the point at which crude oil could leak from broken well casings, pipes and storage tanks.
