Wellbore interference in fractured media

PDF Version Also Available for Download.

Description

In order to bypass wellbore casing damage and reaccess productive reservoir regions, it was decided to sidetrack and redrill the bottom 600 m of production well EE-2 at the Hot Dry Rock (HDR) geothermal site at Fenton Hill, New Mexico. The most desirable new trajectory would maximize reservoir size and minimize water diversion to an older abandoned reservoir. Based on a simple model using Muskat’s analysis it was determined that the new well should be drilled near the old one since water diversion considerations outweighed the advantages of a larger reservoir.
