Microseismic Evaluation of Hydraulic Fracturing Completion Design in Tight Gas Reservoir in Oman

Summary Hydraulic fracture monitoring using microseismic technology is becoming a very popular tool to develop unconventional reservoirs. Microseismic source locations and attributes provide valuable information about hydraulic fracturing growth and containment, and the response of reservoir rock to fluid injection. Such information can be utilized to assess fracturing efficiency, optimize fracturing and completion designs and guide placement of future wells. In this paper we utilise microseismic data acquired during a horizontal well hydraulic fracturing job in a deep tight sandstone gas reservoir located in the Sultanate of Oman. The objective is to assess completion design and fracturing efficiency. The microseismic data is analysed in space and time and the results are compared to the hydraulic stimulation models based on the reservoir geomechanical properties.
