Augmented by the recent activities in the oil and gas industry, it can be easily said that hydraulic fracturing has become a pivotal component for the successful development of unconventional reservoirs. This tremendous growth has fuelled significant advancements in numerical modelling. This paper describes enhanced dynamic simulation assessment of fracture propagation behavior.

Enhanced discrete fracture network methodologies are applied to a shale gas reservoir and investigated with the help of industrial simulators. Fracture parameters along with propagation and interaction behavior between natural fractures and hydraulic fractures are analyzed and quantified. This is followed by verification of the models which further illustrates the accuracy and relevance of the prediction models currently used in the industry. The interaction behavior and quantification of fracture properties is further investigated from the simulation results along with diagnosis of the primary contributors. In addition, a sensitivity analysis is also conducted to examine the hierarchy of the main contributing parameters and their response.


Over the past few decades, in addition to being the prime contributors of the retention, advancements and upheaval of the world economy, oil and gas has been an irreplaceable commodity in our day to life. As the demand for energy steadily increases with each passing year, there is an increase in technological advancements and research in the domain of tapping unconventional resources efficiently and economically.

Hydraulic fracturing has become a pivotal component for the successful development of unconventional reservoirs, mainly shale reservoirs. This paper deals with modelling a set of induced hydraulic fractures in the presence of natural fractures in a shale gas reservoir. In addition, the effect of various fracture properties are investigated in this study. A discrete fracture network (DFN) based simulator (FracGen and NFflow) is used for this purpose which is further extended to Petrel for the propagation part of the study. The constructed model integrates a horizontal well with 10 induced hydraulic fractures and 2 sets of natural fractures in a shale gas reservoir. The interaction, the pressure response and the cumulative gas produced with respect to changes in fracture properties are investigated.
