Underground gas storage facilities are designed for the uninterrupted supply of hydrocarbons for population and industry both within the country and abroad, in case of emergencies. Underground gas storage is an important and complex element of the country gas transportation system, which has its own technological, technical and operational regulations. One of such regulations is to conduct geochemical, geophysical and geodetic measurements in order to detect a breach of tightness of the UGSF, to establish and determine the stressed-deformed state of rock formations and technological equipment, etc. Interpretation of the results of geodetic measurements of the gas storage surface movements due to the technological processes of injection and removal of gas in reservoir-collector into the thickness of the roof of gas storage and determination of the stressed-deformed state of technological equipment and rock formations on this basis are considered in this book.
