The primary field activity for January has been to maintain operations of the plant during extremely cold weather in the early weeks and to maintain and improve on the relative quality of the various pretreatment fluids. Another area requiring attention was changeover of the saturated salt system to a permanent installation. A total of 11,168 and 12,185 barrels of pretreatment fluids were injected into the Chesney and Hegberg patterns respectively. This is a composite average of 42 barrels per day, down eight from the previous month. During January, the number and type of observation wells needed was studied extensively. This resulted in a recommendation for two such wells located between an injection and production well in each pattern. Chemical analyses were performed on various waters, filtrates, and scales in an effort to determine the likely causes of injection problems. A clay study was also directed toward this problem. Remedial well treatments were then recommended. Laboratory work has also included steady-state relative permeability tests, analysis of sulfonates, tests of soluble oil mixtures, flow tests with the preliminary Shell system, study of new polymer samples, and both development and support work relating to well treatments.
