2000 Preliminary <strong>In</strong>vestigation Of A Fusselman Location<br />
(Conducted by GeothermEx, GeothermEx,<br />
<strong>In</strong>c. for Client Company)<br />
Conclusions<br />
- Maximum Brine Rate (self-flowed):<br />
(self flowed): 7,875 bbls/D (125,000 lbs/hr)<br />
- Associated Gas: 315 mcf/D<br />
- Combined Hybrid <strong>Power</strong> Capacity: 1,400 kW (net)<br />
Brine Component: 438 kW (gross) or 300 kW (net)<br />
Gas Component: 1,100 kW (net) (assuming 30% engine efficiency)<br />
- Net Annual Cash Flow/Well: $235,000 (~15 bbl oil/D @ $43/bbl)<br />
Brine: 95% capacity factor at 4.5¢/kWh 4.5 /kWh = $125,000 annual<br />
Gas: 85% capacity factor at 3¢kWh 3 kWh = $246,000 annual<br />
Annual Gross: $358,000/well<br />
Annual O&M: 1¢/kWh 1 /kWh x 1,400 kW = $123,000/well<br />
- Capital Cost: $1,260,000<br />
Binary Plant: $300,000 ($1,000/kW x 300 kW)<br />
Gas Engine: $660,000 ($600/kW x 1,100 kW)<br />
Well Restoration & Other <strong>In</strong>stallment Costs: $300,000<br />
- Payout: 5.36 years ($1,260,000 / $235,000)<br />
- Improve efficiency by specifically designed equipment for recovery. recovery.<br />
- Savings from the economy of scale when several wells are considered together.<br />
- Obtaining renewable power price for the entire project by designing a hybrid facility<br />
that uses both geothermal brine and the gas in an integrated integrated<br />
way.<br />
- Perforate several brine zones to increase production rate; economics based on 200-600 200 600<br />
ft thickness only.<br />
