Well Spacing Optimization to Enhance the Performance of Tight Reservoirs

This paper presents an integrated approach to investigate the impact of well spacing on the performance of tight oil and gas reservoirs depleted by advanced multi-stage hydraulic fracture in horizontal wellbores distributed parallelly in rectangular drainage areas. Thus, an analytical models has been developed considering different reservoir configurations and the associated flow rate, cumulative production, ultimate recovery has been recorded. Also, the pressure behavior for early stages of production conditions and the flow regime dominated by boundary effects has been analyzed. The results indicate that well spacing significantly impacts reservoir performance, particularly at late production stages and that well interference and an ee of well spacing optimization in tight oil and gas reservoirs, offering valuable insights for the strategic planning and development of these vital resources.
