A New Calculation Method for Single Well Controlled Dynamic Reserves of Shale Gas

Tight gas features with low permeability and process of flow is complex. Gas well production is based on dynamic reserves. The traditional methods include volumetric method and material balance formula which uses the shut-in pressure measurement data to calculate the dynamic reserves. This paper raises a new method to calculate dynamic reserves with BHP. The advantage is with no need for shutting well and compared to well-test, the result is accurate.
