Failure Monitoring and Leakage Detection for Underground Storage

Underground compressed air energy storage (CAES) in lined rock caverns (LRCs) provides a promising solution for storing energy on a large scale. One of the essential issues facing underground CAES implementation is the risk of air leakage from the storage caverns. Compressed air may leak through an initial defect in the inner containment liner, such

Leakage risk assessment of a CO2 storage site: A review

Leakage of CO 2 from the storage sites is the major risk associated with a CCS project (Deel et al., 2007).According to the risk profile shown in Fig. 2, the risk of leakage from a storage site is very high when a reservoir/field is gone through injection for the first time (Benson, 2007).This is mainly because of geological complexity and lack of sufficient data to fully

Current practice of early leak detection methods for underground

Fuel (i.e. gasoline and diesel oil) leakage from UST can contaminate groundwater and drinking water with various hydrocarbon contaminants. These leaks create ponds of fuel that spill into the land and aquifers, polluting and seriously destroying habitats. Numerous efforts have been focused on the development of leak detection to the tanks.

A chemical plant undertook a leak-prevention program following a compressed air audit at their facility. Leaks, approximately equivalent to different orifice sizes, were found as follows: 100 leaks of 1/32" at 90 pounds per square inch gauge (psig), 50 leaks of 1/16" at 90 psig, and 10 leaks of 1/4" at 100 psig. Calculate the annual cost

Working behind leaking valves: dilemma between safety and operational

"This is more than enough to handle the majority of the leak rates we experience. In case we have extreme leakage, we will try to reduce the leakage as far as possible anyway (e.g. by greasing), and we can use our DBB-SAVER to handle the remaining leakage. In case the leakage increases again, the DBB-SAVER will alarm us as soon as this occurs.

Highly Uncertain Methane Leakage from Oil and Gas Wells in

Leakage of fluids from oil and gas wells is a source of the key greenhouse gas methane, and presents environmental risks, including groundwater contamination. A loss of well integrity can result in fluid leakage into the annular space between subsequent well casings (which is often vented to the atmosphere) or into the surrounding subsurface. In Canada, industry reporting on
