Fracture Geometry Modeling and Its Effects on Production Estimation in Shale

<p> With time naturally producing reservoirs are depleting and complex zones are explored. With new advancements in Shale gas exploration technology, the better understanding of the production from any reservoir is gained. This study is done to observe the impact of fracture geometry on production in a Shale formation using commercially available reservoir simulation software. From this, it helps to consider the reliability of simulation software. </p><p> Different scenarios of different fracture geometry were modeled for the Eagle Ford reservoir formation. Fracture geometry refers to the number of fractures in each fracture stage. The total fracture volume would be kept constant during the simulation. Production data with respect to time was analyzed and compared to real time field data. </p><p> Simulation results revealed that some of the simulation data could give a close result to actual well production and give reliable results. However, the number of fractures in each stage significantly impacts the oil flow rate as well as the cumulative oil production. The more fracture adding to each stage, the less oil production is expected. In the study, the difference in cumulative production between the least fractures in each stage, 1 fracture, and the most fractures in each stage, 6 fractures, is 400 percent. The models of 1 fracture and 2 fractures in each stage could give the closest result to the actual production; by studying more of these 2 models could give a better estimation for the field.</p>
