Subsurface study of lower Tuscaloosa Formation at Olive Field, Pike and Amite Counties, Mississippi
Olive field is located on the Amite-Pike county line in southwestern Mississippi. The field was discovered by Shell Western Exploration and Production Inc., and produces from a stratigraphically trapped sandstone within the lower Tuscaloosa Stringer Member. The Stringer Member consists of alternating sandstones, siltstones, and shales, and averages 76 m thick at Olive field. The Stringer Member represents a transgressive sequence deposited on eroded Washita Fredericksburg sediments and is overlain by middle Tuscaloosa marine shales. The Stringer Member was subdivided into five zones in this study, based on lithology and electric-log responses. The lower three zones were deposited in a fluvial environment. The sandstones were deposited as point bars and channel sands in a meandering system. Siltstones and shales represent overbank deposits, flood-basin deposits, and channel-fill deposits. The upper two zones consist of sediments deposited at or near sea level. Finely laminated shales and siltstones represent marsh and bay deposits. The top zone is a thin continuous sand body that represents a remnant beach deposited before major marine transgression occurred.
