Caldwell Ranch Exploration and Confirmation Project, Northwest Geysers, CA: 2011 Geothermal Technologies Peer Review Project Summary
The Caldwell Ranch Exploration and Confirmation Project was to drill, test, and confirm the present economic viability of the undeveloped geothermal reservoir in the Caldwell Ranch area. The objective of the project was to re-open and re-complete three wells abandoned in 1999 and 2000: Prati 5 (P-5), Prati 14 (P-14) and Prati 38 (P-38). The data and information collection included: (1) drilling and geology of the subject wells; (2) reservoir production flow rates, temperature, pressure, thickness, permeability, and rock fluid chemistry using new innovative combinations technologies and (3) a determination of present reservoir conditions in order to determine the feasibility of re-developing a steam supply.

卡尔德威尔牧场勘探与确认项目，加利福尼亚州北韦斯特盖泽斯地区：2011年地热技术同行评审项目摘要。卡尔德威尔牧场勘探与确认项目旨在钻探、测试并确认卡尔德威尔牧场区域内未开发地热储的经济可行性。该项目旨在重新开启并重新完成1999年和2000年被废弃的三口井：普拉蒂5号（P-5）、普拉蒂14号（P-14）和普拉蒂38号（P-38）。数据和信息收集包括：（1）目标井的钻探与地质；（2）利用创新组合技术，对储层生产流量、温度、压力、厚度、渗透率以及岩石流体化学成分进行测量；（3）确定当前储层状态，以便评估重新开发蒸汽供应的可行性。
