Chemical Flooding Bridging the gap between chemical flooding and independent oil producers.
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.
Team Stan McCool, Paul Willhite, Tony Walton Mark Ballard, Jyun Syung Tsau, Don Green Grad. Stud.: Ahmed, Lin, Senior Postdocs: Song (Dec), Rondon (Jan)
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
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
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
Salinity (wt% NaCl) wt% Alfoterra® 123-8s, wt% Petrostep® S wt% IBA and 0.05 wt% NaOH; Trembley crude oil; 46.1 °C.
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
Document results and transfer technology Technical papers for SPE Presentations for Independent Oil Operators EKOGA, KIOGA, Wichita SPE
