Multiphase Multicomponent Numerical Modeling for Hydraulic Fracturing with N-Heptane for Efficient Stimulation in a Tight Gas Reservoir of Germany

Conventionally, high-pressure water-based fluids have been injected for hydraulic stimulation of unconventional petroleum resources such as tight gas reservoirs. Apart from improving productivity, frac-fluids caused environmental and technical issues. As a result, much the interest has shifted towards alternative frac-fluids. In this regard, n-heptane, an frac-fluid, is proposed. It necessitates development multi-phase multi-component (MM) numerical simulator fracturing. Therefore fracture, MM fluid flow, proppant transport models are implemented in thermo-hydro-mechanical (THM) coupled FLAC3D-TMVOCMP framework. After verification, model applied to real field case study optimization wellbore x reservoir using n-heptane frac-fluid. Sensitivity analysis carried out investigate effect important parameters, viscosity, injection rate, permeability etc., on fracture geometry with proposed fluid. The quicker closure flowback compared advantageous better placement, especially upper half early start natural production Finally, designs minimum dimensionless conductivity 30
