Emerging Resources<br />
Co-production with Oil Wells<br />
•Generating power from produced water<br />
–Reduce well field operating costs<br />
–Eliminate fossil fuel consumption<br />
–Reduce maintenance costs<br />
•Introduce emission free energy production<br />
•Allow for green energy tax incentives
Emerging Resources<br />
Co-production with Oil Wells<br />
•Resource chemistry<br />
–Major factor is heat exchanger lifespan<br />
–Fouling and corrosion will reduce HEX life<br />
–Increased O&M costs will reduce economic benefits<br />
–Every resource is different<br />
•Cooling<br />
•Water cooling requires cooling tower, constant makeup<br />
water, and additional pumps<br />
•Air cooling (dry cooling) can be utilized anywhere
Emerging Resources<br />
Co-production with Oil Wells<br />
•Major design factors of a geothermal power<br />
plant<br />
–system simplicity<br />
–maintenance requirements<br />
–reservoir management<br />
–environmental considerations<br />
–power plant reliability

Emerging Resources<br />
Co-production with Oil Wells<br />
•Pioneering low temperature geothermal for 30<br />
years (mostly water cooled)<br />
•Recent successes using air (dry) cooling<br />
•More applicable for remote generation<br />
•Co-produced water offers a generous resource<br />
•Challenges: reliability
Emerging Resources<br />
Co-production with Oil Wells<br />
•RMOTC pioneers co-produced oil field<br />
production<br />
•Ormat continues its track in pioneering<br />
innovations
