The three-year contract expired on August 28, 1978, without completion of the original intent of testing the effectiveness of carbon dioxide on effective enhanced oil recovery agent, owing to unforeseen problems of environment control, the dump flood and extreme weather condition. However, all of the preparations for carbon dioxide has been accomplished and the pilot is in excellent condition for proceeding with the program. Although cost overruns may be over $1,500,000, additional testing over that programmed indicates that the pilot operation will be more successful than previously hoped for. Guyan Oil Company has developed a two year plan of operation to complete the program.
