A Dynamic Reserve Evaluation Method for an Ultra-Deep Fractured Tight Sandstone Gas Reservoir

Blog Article

Dynamic reserves evaluation is crucial for the development and assessment of gas reservoirs.However, ultra-deep fractured tight sandstone gas reservoirs pose unique challenges due to their abnormally high pressure, tight matrix, and complex fracture distribution.This paper proposes a simplified forward calculation method that canon imageclass mf227dw incorporates the fracture length for the rapid estimation of dynamic reserves in fractured tight sandstone gas reservoirs.This method was based on the pressure change rate equation and considered the unique characteristics of fractured gas reservoirs.Numerical simulations were conducted to analyze the sensitivity of g35 coupe fender the proposed method.

The proposed method was applied to estimate the dynamic reserves of a fractured gas reservoir, and the results closely approximate the well group method, indicating its accuracy.The main advantage of this method lies in its simplicity, allowing field engineers to perform rapid dynamic reserve evaluations.
