Abstract
In the development of gas fields, reservoir pressure can be used to estimate gas reserves by means of the material balance methodology and to calculate drained reserves. This provides an indication of the effectiveness of the development system. The authors of the article suggest a methodology for determining drained reserves in wells without reservoir pressure measurements. This approach is useful if the well stock is put into operation concurrently or within a brief period of time. Numerical modelling and analysis of field development data have led the authors to conclude that the current flow rate of wells, the hydrodynamic parameters of the productive formation and the interference of nearby wells are the most significant factors controlling the amount of drained reserves. The use of this technique will improve the understanding of the current processes occurring in the reservoir, clarify the assessment of the energy of the deposit and the value of the initial gas reserves, and also create an additional source of information for timely and more accurate decision-making in field development. Adopting this methodology can improve the understanding of ongoing processes in the reservoir, enhance evaluations of reservoir energy and initial gas reserve sizes, and provide additional information resources for making decisions on field development in a more timely and precise manner.
