Modeling Fracture Propagation in a Dual-Porosity System: Pseudo-3D-Carter-Dual-Porosity Model

Despite the significant advancements in geomodelling techniques over past few decades, it is still quite challenging to obtain accurate assessments of hydraulic fracture propagation. This work investigates effect fluid leak-off a dual-porosity system on propagation geometry, which, turn, affects hydrocarbon recovery from tight and unconventional reservoirs. Fracture within reservoirs was analyzed using Pseudo Three-Dimensional-Carter II model for single- (P3D-C) systems (P3D-C-DP). Previous studies have accounted single-porosity models; however, are limited. We present novel approach coupling along with fracture-height growth mechanism. Our findings provide important insights into complexities fracturing treatment design our new pragmatic modeling approach. The simulation results illustrate that contributes confined half-length (xf), 31% smaller P3D-C-DP as opposed (P3D-C). As height (hf), resulted 40% shorter compared model.
