Hydraulic Fracturing Design and Optimization in One of the Iranian South Oil Reservoirs

AB is a low permeability carbonate reservoir with a substantial volume of oil in place and reserve. an important part of management of this reservoir is currently improving oil deliverability. reservoir characterization showed that this reservoir has substantial oil in place and good porosity. due to low permeability, the wells produce in low productivity index and low drainage area. on the other hand, the reservoir is layered and there are dense layers in top andbottom of each producing layer and act as stress barriers. as a result of these characters, the reservoir is selected as hydraulic fracturing treatment candidate. In this paper, we will outline thesteps required to implement hydraulic fracturing process from data sets to fracturing design andoptimization. This paper is organized in two parts. First, Due to limited data available prior to executing the frac design, we discuss developing a complete and accurate data sets which isrequired for fracturing design in AB reservoir. Then we discuss and analyze the results of 3D fracturing model design on a sample well of AB reservoir using proper softwares.
