Abstract
Identification of underground gas storage facilities (UGSF) deformations is necessary for designing leakage prevention and clearing. As shown in this work, a reliable subsurface method, which can fix second gas accumulation sections like a direct evidence of UGSF integrity deformation at presence of numerous artificial conductors (downhole equipment, pipes, wirelines and etc.) is the near-field transient electromagnetic sounding method. Theory aspects and techniques of this method are considered, cases studies of its use on several UGSF are described and efficiency of its application for UGSF integrity monitoring is shown.
