The Adena J sand field is the largest field to date in the Denver-Julesburg Basin (Fig. 1). This field is located in Morgan County, Colo., approximately 12 miles south of Fort Morgan. The discovery well in the Dakota J sand was drilled in Nov., 1953. By late 1954 initial development was completed with the drilling of 166 oil wells and 15 gas wells. Early in 1954 the operators recognized the advantages of unitization and committees were organized to conduct the necessary studies. On Jan. 1, 1956, a large portion of the field was unitized with The Pure Oil Co. named as Unit operator. Nine months later additional leases were brought into the Unit. All but three of the J-sand wells in the field are now participating in this Unit.
Early in Feb. 1957, plans for a pressure maintenance program were completed. In July, 1957, water injection was started into a line of wells along the gas-oil contact. This plan of water injection requires only a portion of the wells presently completed in the field to produce the reservoir. Conventional production operations under this pressure maintenance program would have required extensive tank battery relocation, and in addition would have required an elaborate produced water gathering system. An economic study of various producing operations led to the selection of automatic custody transfer equipment and well supervisory control equipment.
Studies revealed that the most desirable system should include one central treating plant and custody transfer station. Distances involved were too great to permit each well an individual lead line to a central station, or to provide supervisory well control from one point. To overcome this problem it was decided to control the wells from stations spaced through the field. Production arriving at each station could be transported to the central treating and custody transfer station through an oil-water gathering line. It became readily apparent that three major problems had to be solved in the system design.
