Abstract
Sandia National Laboratories Geothermal Technology Development Division is working to advance the state of the art lost circulation prevention and control. For this purpose, a large scale Lost Circulation Test Facility was designed and built. This paper addresses the evaluation of candidate lost circulation materials using this facility and also using the recommended practice of ApI RP 13I. Test results from these facilities are compared and discussed for the materials tested.
