Detection conditions of gas-saturated layers by the result of complex interpretation of non-electrical well logging data

Abstract

Summary Possibilities of using non-electrical methods of well logging to detect gas-saturated objects are considered. Determination of the gas saturation coefficient is proposed using two different approaches - traditional according to electro-logging and additional - when estimating the component composition of rocks according to the methods of acoustic and radioactive logging. Significant values of gas saturation, which are recorded according to non-electrical methods, are possible only in the absence of an invaded zone. Leaks of gas-saturated objects in the well sections can lead not only to the loss of part of the gas production reserves, but also to unforeseen accidents during drilling and operation of wells.
