Application of acid fracturing, water flooding and energy curves in reservoir reformation in the Tahe oilfield

For fractured-and-vuggy carbonate reservoirs in the Tahe oilfield, we proposed a dynamic analysis method composed of three types of curves. We used acid fracturing curves to study reservoir relationship, water flooding curves to study volumetric changes, and energy curves to study drainage radius changes. Combined with the previous static methods to identify cave center, the dynamic method successfully guided field practice and reservoir reformation, hence maximized well control reserves.
