Presentation Transcript

  1. Chemical Flooding Bridging the gap between chemical flooding and independent oil producers.

  2. Objective To design efficient chemical flooding processes for KS leases/reservoirs. The designs are necessary for Independent Oil Operators to make an informed assessment for implementation of a pilot or demonstration project.

  3. Team Stan McCool, Paul Willhite, Tony WaltonMark Ballard, Jyun Syung Tsau, Don Green Grad. Stud.: Ahmed, Lin, Senior Postdocs: Song (Dec), Rondon (Jan)

  4. Tasks I. Identify and select 10 leases II. Design efficient chemical formulations III. Simulate field applications and evaluate economics for 2 leases IV. Document results and transfer technology

  5. Identify/Select Leases Methods Public data (KGS) Not successful Interviews with operators Top 30 producers Top 10 is SE KS 45% KS oil production Criteria Successful waterfood

  6. Define Efficient Chemical Systems Laboratory tests on 10 crude/brine samples Acid number of crude oils Trembley and Wahrman leases Phase behavior studies Flow Tests in rocks Mobility of polymer solutions

  7. Trembley Crude Oil at 115°F

  8. Salinity (wt% NaCl) 0.625 wt% Alfoterra® 123-8s, 0.375 wt% Petrostep® S-2 0.75 wt% IBA and 0.05 wt% NaOH; Trembley crude oil; 46.1 °C.

  9. Simulate field applications and evaluate economics • Develop geological models • History-match primary and secondary processes • Conduct simulations of chemical floods • Estimate costs • Determine ROR for pilot and field projects

  10. Document results and transfer technology • Technical papers for SPE • Presentations for Independent Oil Operators • EKOGA, KIOGA, Wichita SPE
