Abstract
|
The report presents the results of an investigation of materials and mechanisms with potential for use in Enhanced Geothermal Systems wells as temporary diverters or lost circulation materials. Studies were also conducted with regards to particle size distribution and sealing effectiveness using a lab-scale slot testing apparatus to simulate fractures. From the slot testing a numerical correlation was developed to determine the optimal particle size distribution (PSD) for a given fracture size. Field trials conducted using materials from this study were also successful.
