Information in this report is presented under the Work Breakdown Structure (WBS) elements: WBS 2100 - Fluid Injection; WBS 2300 - Performance Monitoring; and WBS 2400 - Economic Monitoring. WBS No. 2100 - Fluid Injection: (1) in an effort to increase injection in some of the 5.0-acre pattern area injection wells, a treatment program was undertaken in late 1984. A discussion of the treatment program and its results is given; (2) water softening was discontinued in the 2.5-acre pattern area during the year; (3) in December 1984, the biocide used at the M-1 was switched from Tretolite X-CIDE 510 to Tretolite X-CIDE 215; and (4) polymer concentration was reduced from 625 ppM to 411 ppM at the 5.0-acre pattern area during 1985. WBS No. 2300 - Performance Monitoring: (1) present oil cuts at the 2.5- and 5.0-acre pattern areas are 1.5% and 5.2%, respectively; (2) the final annual transient test results for the six injection wells and their offsetting producing wells are reported. The results are compared to previous years' results and are presented in tabular form; (3) subsequent to the injection of tritiated water into ten injection wells, all producing wells are being analyzed regularly for the presence of tritiated water. To date, 132 project wells have shown the presence of tritiated water; and (4) samples of produced water have been analyzed bi-monthly for sulfonate content. Data from the most recent analysis is presented and compared to earlier data collected. WBS No. 2400 - Economic Monitoring: (1) two producing wells in the 2.5-acre pattern area of the M-1 Project were abandoned during the year; and (2) with the 2.5-acre pattern area nearing its economic limit, several of the producing wells in this area have been temporarily shut-in pending an evaulation of their remaining potential. A discussion of the economics justifying the shut-ins is presented. 20 figs., 4 tabs.
