TL;DR: In this paper, the authors proposed a new concept to describe the rock elastic energy and water influx energy using the linear relationship of cumulative production, which simplifies the MBE and converts to a multivariate nonlinear equations.

TL;DR: In this article, the authors provided a water breakthrough risk evaluation method and evaluation device for a water-carrying gas reservoir gas well, and the method included the following steps that an evaluation factor which influences the water breakthrough risks of the water-carving gas reservoirs gas well was built; the weight vector of the evaluation factor was obtained on the basis of the analytic hierarchy process; a fuzzy relation matrix between the water burst risk of the WRSG and the evaluation factors was constructed; and the fuzzy relations were combined according to a weighted average fuzzy composition operator.

TL;DR: In this paper, a method and a device for judging a single-well water invasion situation of a water-carrying gas reservoir and controlling gas well production is presented. But the method is not suitable for the case of single well water invasion.

TL;DR: In this article, the authors proposed a method and device for improving recovery efficiency of a condensate oil and gas reservoir through a single well circulation gas injection, which comprises a single-well production-injection tubular column, a three-phase separator and a compressor.
