Optimization of hydraulic fracturing with rod-shaped proppants for improved recovery in tight gas reservoirs

Abstract Due to the increasing demand and importance of natural gas in global energy mix, its expeditious recovery is crucial, especially from large-scale unconventional geo-resources. Hydraulic stimulation an established means productivity increase tight reservoirs. The fracture conductivity generally depends on proppant properties, particularly shape. Therefore, this research, effect using rod-shaped proppants was investigated. Using instead conventional spherically shaped proppants, can make a significant difference. cylindrical shape, higher porosity permeability are generated, resulting better fractures. Thus, analyze different shapes post-fracture performance, production model implemented FLAC3D plus -TMVOC framework. Later, in-depth sensitivity analysis performed investigate effects size, strength, effective stress aperture reduction due deformation embedment. application generic revealed that be increased by about 7% aspect ratio 1 with same diameter as spherical proppant. Then, size 1–10 significantly 13% but results deformation. Finally, fracturing proposals well x reservoir Germany showed could improved if replaced proppants.
