A New Real-Time Gas Well Productivity Evaluating Method

Abstract:

With the continuous development, the gas well productivity will decrease. The deliverability test can be used to evaluate gas well productivity, but this method always needs long test which will affect daily production seriously, especially for low permeability gas wells, also there always isn’t enough data in the field. Aiming at this problem, this article presents a new real time method to get the gas well productivity. This new method avoids deliverability test and only needs daily production and wellhead pressure data, so the analysis process is easy and this method has strong practicality. It is proved that this new method works well in the field case.

[7] Start with the material balance equation: (A-1) Differentiating partially with respect to real time, t, we get (A-2) Re­arranging: (A-3) where (A-4) Define pseudo-pressure as (A-5) Similarly from partially differentiating Equation (A-5) with respect to p, we get (A-6) For the gas compressibility is defined as (A-7) We also can recognize that (A-8) Substituting the values from Equations (A-4), (A-6) and (A­8) in Equation (A-3), it follows (A-9) At this point, it is appropriate to introduce the definition of material balance pseudo-time for gas. (A-10) So the integer form of Equation (A-9) is (A-11).
