Abstract: Dynamic digital reservoir characterization and management Carthage Field, Panola County, Texas
A comprehensive dynamic-digital database was used to drive the development of the Carthage Field in Panola County, Texas. All available well data associated with logs, tests, completions, and production was collected for over 2000 wells and loaded into an integrated database system. A detailed stratigraphic framework was created for a 3500-foot productive interval composed of marine wave-dominated coastal sands, parallic incised valley-fill coastal plain sands, and oolitic-limestone shoals of the Cotton Valley, Travis Peak and Petit formations. All correlation work was performed digitally using both raw and normalized log data. Petrophysical analysis generated net-sand values and pay flags for each of 70 stratigraphic zones. Production tests, interpreted production logs and historical production data were used to gauge the productivity of the 70 correlated stratigraphic zones. Maps were generated to identify the spatial extent of the zones.
Processes that are currently being supported by the Carthage digital database include, field depletion plan, field development planning, recompletion program, wellbore utilization plan, production rate acceleration, and reservoir surveillance.
As wells are drilled, the information is fed back into the integrated database enabling accurate prediction of new drilling recoveries. The accumulated data and knowledge has been successfully used in the exploitation of the Carthage Field, turning an 18% natural decline into a 5% incline.
