| Abstract: | This study examined the stratigraphic architecture, depositional and diagenetichistories, and resulting reservoir characteristics that have influenced the occurrence,distribution, and quality of flow units in the Diamond M field, Scurry County, Texas.The study area is located in the Midland Basin. The field has production from theCanyon (Pennsylvanian) Horseshoe Atoll carbonate buildup. Recent drilling in theDiamond M field was done to evaluate ways to improve recovery by water flooding.Classification of depositional texture based on detailed petrologic and petrographicstudies on three cores was done. Subsequent genetic classification of pore types by thinsection petrography revealed three dominant pore types: intramatrix, moldic, and vuggy.The reservoir was zoned according to dominant pore type and log signatures to evaluatecorrelations at field scale by using neutron logs. Equations determined from coreanalyses provided equations used for estimating porosity and permeability, which wereused to develop a ranking scheme for reservoir quality based on good, intermediate, andpoor flow units at field scale. Ultimately slice maps of reservoir quality at a 10 ftinterval for a 150 ft section of the Canyon Reef reservoir were developed. These reservoir quality maps will provide a useful tool for the design and implementation ofaccurate and profitable development programs. |
