Stratal SliceStratal SliceFrequency ContentFrequency Content

Document pressure propagation preceding CO2 plume

Time lapse bottom-hole pressure in pattern – numerous wells

Pressure has returned to near pre-production – unique conditions for an oil field

Complex fluid mixture – oil +methane+ brine

• Measure fluid composition change –sweep efficiency– Determine effectiveness of available tools

• Document efficiency of Mississippi oil and gas law in retaining CO2– Wells drilled in 1940-1950, P&A 1965– Cement behind casing in injection zone– Evaluation – reentry or soil gas survey– Above zone monitoring program – pressure - fluid if needed

Phase II Monitoring GoalsPhase II Monitoring Goals

Dedicated observation wellThree mechanical packer – two perforation zone completionTwo downhole pressure/temperature Panex gauges – high reliabilityReal-time readoutEpisodic logging Limited fluid sampling

• Array of time-lapse monitoring between injector and producers– Model match/ compared to response in dedicated observation well – Logging program – measure sweep efficiency

• Programmatic value– Improved capacity estimate– Increase skill in measurement of pressure response preceding plume – Document well integrity
