A new geographic information system (GIS) for the oil and gas fields in Ohio is being used to determine the best candidates for geologic CO2 sequestration. Individual oil and gas fields have been defined by mapping individual areas of oil-and-gas production by producing geologic formations. By defining fields by the geologic formation, a more detailed approach can be made for assessing individual fields as potential candidates for CO2 sequestration and/or CO2-assisted enhanced recovery.

The oil and gas fields GIS will be linked with Ohio’s oil-and-gas-well data system, RBDMS (Risk-based Data Management System), and oil-and-gas production database, POGO (Production of Oil and Gas in Ohio), to allow greater flexibility of mapping and analyses. Linking of these databases will make it possible to dynamically update individual oil-and-gas field statistics and to modify or create field outlines as new drilling continues.

Each oil-and-gas field will contain associated attributes (where available) that include reservoir characteristics (e.g., average depth, lithology, porosity, permeability, reservoir temperature, and net thickness), production data (e.g., cumulative production, original-oil-in-place, and remaining-oil-in-place), and fluid characteristics (e.g., oil gravity, oil viscosity, and average water saturation). By relating these oil and gas field attributes, analyses will discern the best candidate fields for CO2 sequestration storability in depleted oil-and-gas fields and determine the oil-and-gas fields with the best potential for enhanced-recovery operations by injection of CO2.
