The depositional environment of the late Eocene Reeves sand in southeast Beauregard Parish and southwest Allen Parish, Louisiana, was identified. In this study, the depositional environment of the Reeves sand was determined from interpretation and integration of geological and geophysical data. Spontaneous potential (SP) and resistivity log signatures were used to determine the thickness and distribution of sand in addition to aiding in interpretation of its depositional characteristics. Multiple seismic attributes, including amplitude extraction and similarity extraction, were interpreted and mapped using the SMT Kingdom suite. These maps were compared to equivalent maps created from the well log data to correct for inconsistencies between them and enhance identification of the depositional environment of the sand. By integrating this data, different sand bodies, including distributary channel, distributary mouth bar, and offshore bar, were identified, which are created from lower deltaic and shelf processes. The integration of multiple data types allows for an accurate depositional model to be applied that is representative of the Reeves sand within the study area. Understanding of the Reeves sand depositional environment will enhance understanding of the regional depositional history of the Cockfield Formation and future success of hydrocarbon exploration and development.
