CONCEPT OF LEAK TIGHTNESS MONITORING AT UNDERGROUND GAS STORAGE

Abstract

The most important part of the operation of each underground gas storage facility is the implementation of a regular monitoring system for leak tightness monitoring. This article deals with the design of a proposal leak tightness monitoring concept in underground gas storage in porous reservoirs (depleted gas/oil reservoirs, aquifer reservoirs). This concept interconnects all commonly used and established leak tightness monitoring methodologies and evaluates them in time with a comparison with historical results with reference to possible solutions or implementation of remedial measures.

Keywords: underground gas storage, leak tightness, well integrity
