Observations of joint persistence and connectivity across boreholes

PDF Version Also Available for Download.

Description

Observations of joint persistence and connectivity are made by comparison of digital borehole wall images of fractures, fluid conductivity logs and hydraulic injections test results. The fractures were found to be generally impersistent across vertical boreholes about 8 m apart. Many hydraulic connections were found in the same volume of rock. Direct connections through single fractures seem to be rare and connectivity appears to be controlled by fracture networks, even over small volumes.
