Background & Evaluation History

Madison reservoir discovered January 1954

Waterflood initiated in 1959 with peripheral flood

Water injection expanded to pattern flood through 1964 -

Reservoir developed with 36 completions

Currently have 21 active wells including 12 producers and 9 injectors

Current Production of 300 bopd, 29,000 bwpd & 13,000 bwipdCO2 flood potential originally identified in Amoco’s 1987 CO2 Feasibility

Study

• Determined marginally economic in 1987(low oil price)• Identified additional data needs to mitigate risk

Devon revived the project idea in January 2005
