Future for geopressured-geothermal resources
The geopressured-geothermal production technologies for recompleting the Hulin Well and design and operation of surface facilities appear to be well in hand. A preliminary capital cost estimate indicates $4.45 million is required to recomplete and prepare the Hulin Well for production testing. The planned recompletion of the production well, surface facilities, and disposal well will have the capability to handle 24,000 barrels per day (bpd) of brine. If the reservoir can produce this design flow of brine saturated with gas, and the gas can be sold for $1.30/thousand cubic feet (mcf), DOE should have a positive cash flow about $530 per day for the first year. If gas zones are located above the brine as indicated by logs, the positive cash flow could reach $4130 per day or higher. The principal uncertainties are the gas content of the brine and the reservoir performance, both initially and long term. A private developer would need a market price for natural gas of from $1.38 to $4.60 per mcf for a reasonable return on investment depending on the reservoir performance and whether or not zones of excess gas are actually encountered. 7 refs., 6 figs.
