Downhole probes evaluate cavern integrity
- TransGas Ltd., Regina, Saskatchewan (Canada)
Obtaining natural-gas storage caverns` pressures and temperatures with downhole probes has allowed TransGas Ltd., Regina, to monitor and evaluate cavern integrity. TransGas has more than 5 years` experience with the devices. The acquired data have also helped determine gas-in-place inventory and confirm and assess changes in spatial volumes. These changes may have resulted from cavern creep (shrinkage or closure) or downhole abnormality such as fluid infill or collapse of the side walls or roof. This first of two articles presents background and many of the details and lessons to date of TransGas` cavern gas-storage probe program; the conclusion describes a specific storage site with some results.
