Carbonate Reservoirs

Reservoir Class Program

Program Goals: Slow oil well abandonment rates and preserve industry

infrastructure Demonstrate improved methods of reservoir

characterization, advanced oil recovery, advanced environmental compliance techniques, and improved reservoir management techniques

Broaden information exchange and technology application among stakeholders

Program Benefits: Extend economic production of domestic fields Increase ultimate recovery in known fields Increase domestic oil reserves Decrease cost of environmental compliance

The DOE Report on Field Demonstrations presented to the National Research Council in November 2000 stated that the realized benefit in production and taxes returned to the government was

$30.5 billion for $136 million spent

These Projects Have More Than Returned The Cost To Fund Them

Reservoir Class Program

Accomplishments: The University of Utah with Aera Energy successfully

reestablished production in an abandoned lease. Production from the 40-acre property has risen to over 1,200 bopd and in 5 years over one million bbl of oil has been recovered. The adjoining leases have a potential for 80 million bbls of oil.

University of Kansas: Stewart Field has shown an 11-fold increase in oil production since 1993. Significant cost savings have been realized at Savonburg Field.

Hughes Eastern extended the life of North Blowhorn Field, AL by 12 years with MEOR

Laguna Petroleum Corporation extended reservoir life of South Cowden and Foster Fields, TX by 7 years, and identified 570,000 bbl new reserves through seismic interpretation

Michigan Tech. University drilled the 1st horizontal well in the Michigan Basin. Over 20 permits were issued to drill “look alike” prospects in the Michigan Basin.

Class II Shallow-Shelf Carbonate Reservoirs

9 field demonstrations in shallow-shelf carbonate reservoirs were selected and awarded in 1994

6 additional projects in Class II were selected and awarded in 2000

Class II Projects

The Future of Field Demonstrations

DOE will continue to support field demonstrations through the Advanced Technologies Initiatives targeted toward the needs of independent producers

Reservoir Characterization is essential Technology Transfer is essential Good Ideas are essential – Thanks go to those

who brought us the great ideas
