The accurate determination of reservoir lithology remains a challenge in petroleum engineering. There are some conventional techniques available to determine the lithology. However, the application of those techniques has been long and complex. So, the main goal of this study is to simplify identification of reservoir lithology. This paper presents a Pattern Recognition Approach (PRA) to identify the reservoir lithology. Four wells from the Camaal field were chosen to develop this approach. Around of 32400 data points from the previous wells were digitized by Neuralog program (2015). The PRA approach used depth, gamma ray, lithology, sonic, neutron and density logs as inputs. Data were classified into three portions: 70% as training data and 15% as testing data and 15% as validating data.
