Gas well testing (GWT) is one of the principal methods for estimating its flow potential and to determine reservoir properties and bottom-hole area conditions. Further, it allows to make use of non-linear filtration influence. Reliability of GWT results is important for the choice of field development strategy and production stimulation.
The paper focuses on non-linear filtration research, but unlike to well-known purely theoretical results, we developed a set of guidelines designed to conveniently process and interpret field data. We state that modern mathematical methods such as wavelet analysis and accurate planning of field experiments are key in order to acquire more reliable information about reservoir and well properties. This approach can further be applied to lay out the Arctic shelf gas reservoir engineering and planning the well intervention techniques.
