Abstract: The study illustrated logging analysis in a case when a drilling well has to be stopped by a technique accident after a thickness of only 1.01m is drilled down into the possible oil/gas horizons.In such a circumstance,the study affirmed the petroliferousness of a new exploratory region,by a full use of the measuring data from gas loggings.Moreover,these data can be significant either for a prospect evaluation,or as a compensation for the loss of drilling accident in potential evaluation of new oil/gas horizons in a new region.
