WBS No. 2100 - Fluid Injection: (1) Polymer injection has continued in varying concentrations. During the interim of October 1, 1982 and September 30, 1983, the polymer concentration was reduced from 411 ppM to 200 ppM and then to 100 ppM on the 2.5-acre pattern. The 5.0-acre pattern has remained at the same 625 ppM polymer concentration. (2) A change from bulk Dow 700 to bag Dow 700 polymer was made during 1983. The previously purchased bag polymer has been stored since the start of the M-1 Project. WBS No. 2300 - Performance Monitoring: (1) Subsequent to injection of tritiated water into ten injection wells, produced fluids from all oil wells have been analyzed monthly for the presence of tritiated water. During August, 1983, 29 wells showed the presence of tritiated water as compared to 77 wells in August, 1982. (2) Samples of produced water have been collected monthly and analyzed for water soluable sulfonate content (a micellar slug component). Analysis of sulfonate production shows 88% and 36% of the 2.5- and 5.0-acre patterns' wells respectively have fallen off peak sulfonate response. (3) Presently, the 2.5- and 5.0-acre patterns are producing at oil cuts of 3.2% and 8.7%, respectively. (4) The annual transient test results for the six injectors and their six offset producers are reported. The results are compared to previous years' results and indicate an increase in skin damage in the 2.5-acre pattern injectors and a generally increasing fluid mobility in the 2.5- and 5.0-acre patterns. (5) Core analysis data are presented for three core test wells which were drilled in the 2.5-acre pattern to compare slug and polymer swept sand intervals to the induction log calculated swept intervals in the offset observations wells. 24 figs.
