In May 2006, an independent review by GeothermEx, Inc. of Richmond, California, provided a preliminary estimate of capacity at Crump Geyser, a minimum of 40 MW and most likely 60 MW. The Crump Geyser area is located within the moderate to high thermal activity zone, which extends from Washington State and covers much of central and eastern Oregon. The Renewable Northwest Project considers the Basin and Range country of southeastern Oregon one of the most promising geothermal areas in the Pacific Northwest (www.rnp.org). In 2009 and beyond, NGP intends to continue exploration surveys to advance the Crump Geyser project through reservoir drilling, testing and confirmation and project feasibility studies. Crump Geyser geothermal project highlights are:
The Crump Geyser was formed as a result of a well drilled by Nevada Thermal Power Company (Peterson, 1959). In the 1950's, the Company conducted a systematic drilling program in this part of Oregon, Nevada, and California, in a search for a source of natural superheated steam. Nevada Thermal Power Company (NTPC) was a division of Magma Power Company of California. Two days after the completion of the hole, the well erupted sending a column of steam and hot water 45 m in the air. It was, at this time, the site of the largest continuously erupting geyser in the United States. The geyser was vandalized in the early 1960's. Several boulders were thrown in the casing, after which the behavior of the geyser changed. It continued erupting, but only to a height of approximately 18 m, and with periods of inactivity of about 2 minutes. The geyser has been active for several years. |
