AB  - The process of developing shale reservoirs has proceeded to the point where new wells are drilled in close proximity to the "parent" well. These new wells pose a problem for operators because they can lead to complicated interactions between wells, reducing the performance of either one or both of the parent and child wells. A successful field development near producing wells requires careful consideration of the distance between wells to minimize the volume of unproduced gas and loss of revenue. In the oil and gas industry, appropriate horizontal well spacing is often determined by a combination of geological modeling with reservoir simulation. The goal of this research is to identify the best field development approach that maximizes both gas production and financial return. In the course of our study, a shale gas reservoir is modeled using flow simulation-based reservoir simulation, to carry out a sensitivity analysis that will help optimize shale gas production in the future, and we took into account the adsorption/desorption phenomenon, the geomechanics effect coupled with the heterogeneity property, which are very characteristic of real shale gas reservoirs. For 20 years of gas production, we sought first to find optimal well numbers and geometries scenarios. Then we decided to intelligently down space the horizontal wells with multiple hydraulic fracturing stages by adjusting the distance at different completion times between parent well(s) and child well(s). We investigated both lateral and vertical well spacing in order to achieve the highest possible volume of gas production and amount of net present value (NPV). According to the findings of our simulations, ten wells with aligned well geometry provide the most economic benefit for the optimization strategy. In order to maximize the gas recovery, the lateral well spacing needs to be greatly increased, and the vertical well spacing needs to be decreased to a point where more gas can be produced from each well.
