Some problems in respect to determination of a safe packer operation conditions of a gas well in case of pressure presence in the annulus
The article discusses the problems in relation to the diagnosis of the causes of annulus pressure occurrence in gas wells. The possible reasons for wells integrity loss are presented. Showing Various methods of diagnosing tests to determine the source of annular pressure occurrence are shown. An algorithm to determine the causes of the annulus pressure occurrence is developed. Determination of the causes of annular pressure occurrence in a gas well allows finding the possibility to regulate the order of wells safe operation in future.
