Purpose of this field test is to demonstrate an improved oil recovery process which will displace economic quantities of otherwise nonrecoverable viscous oil from this reservoir, as well as to determine its suitability for application to other sites. All tasks in Phase A, with the exception of Task No. 5, have been finished. Phase A encompassed the preliminary systems design laboratory work and pattern optimization leading to Decision Point No. 1. Because Task No. 5, sulfonation of a Wilmington crude feedstock, was an integral part of the subjects to be resolved under Phase A, Decision Point No. 1 must be delayed several months. Marathon was unable to schedule sulfonation of Wilmington feedstocks; they are now conducting bench sulfonation of Wilmington feedstocks and have called upon Witco and Stepan to prepare Wilmington sulfonates in their respective pilot plants. Additional laboratory work will be required under Phase B for Tasks No. 1, 2 and 3. Although flood tests and polymer absorption-degradation tests were performed on core material from the Upper Terminal sand, this material was decidedly not fresh.
