Abstract
Lost circulating is an expensive and often encountered problem when drilling into geothermal formations. A method is needed to more accurately describe loss zones encountered during geothermal drilling to allow for more realistic testing since present testing techniques are inadequate. A Lost Circulating Zone Mapping Tool (LCZXMT) is being developed that will quickly locate a loss zone and then provide a visual image of this zone as it intersects the wellbore. A modified Sandia high temperature Acoustic Borehole Televiewer should allow modeling of geothermal loss zones, which would allow modeling of geothermal loss zones, which would turn lead to testing that can be performed to evaluate lost circulation materials under simulated down hole conditions.
