                           Carbonate Reservoirs

   Rhonda Lindsey, Senior Project Manager
    National Energy Technology Laboratory
            Reservoir Class Program

 Program Goals:
    Slow oil well abandonment rates and preserve industry
    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
These Projects Have More Than Returned
        The Cost To Fund Them

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

             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.

             Laguna Petroleum

 Infill well, Foster lease
            Crystal Field, MI
     Michigan Technological University

   Drilling Michigan’s first horizontal well
                  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
