Although no field tests have been conducted by the Laramie Energy Research Center (LERC) since the Second Annual Underground Coal Gasification Symposium, additional analyses of data from the Hanna II tests have been completed. These analyses consist of energy balances, thermal efficiencies, and process efficiencies for all phases of Hanna II. In addition, preparation for the Hanna III and IV tests is in progress and preliminary planning for Hanna V has been completed. Simulation of in situ coal gasification on a laboratory scale is also being, pursued. This paper will discuss the additional analyses of the Hanna II test, describe the Hanna III, IV and V tests, and outline the objectives of the laboratory simulation experiments.
