Stress evolution and fracture propagation of infill well after production and injection of parent well in a tight oil reservoir

Abstract Stimulation of unconventional tight oil formations via horizontal wells has seen increasing cases fracturing infill in recent years. The effectiveness such a strategy is mainly dependent on the proper characterization stress evolution and an accurate forecast subsequent fracture propagation region neighboring after considering production performance injection schemes parent wells. In this respect, comprehensive approach was proposed to simulate caused by can also predict upcoming behavior well. It found that depletion result dramatic changes field, highlighted apparent decreases magnitude minimum its orientation. Controlled reproduce original which favors transverse extension network contrast, soaking well alone little effect improving field. Therefore, study suggests optimal for provides insights cluster designs well, eventually leading maximized productivity
