Abstract
Completion of the commercial sized Hot Dry Rock Geothermal Energy Project requires that hydraulic fractures be created between two inclined wellbores at a depth of about 4 km (15,000ft). Isolation of a section of the open wellbore is necessary for pressurization to achieve the fracture connections. A cemented in liner/PBR assembly is one of the methods used for zone isolation near the bottom of the injection well. A downhole, pumped cement test was first conducted at a wellbore temperature of 275°C (525°F) to determine if a suitable slurry could be designed, pumped, and later recovered to assure the success of the cemented in liner operation.
