Re-using old Formation MicroScanner logs to help understand reservoir and fracture development at the Dover East Field, SW Ontario, Canada

摘要

Schlumberger ran three FMS (Formation MicroScanner) logs in 1988 over the Black River oil bearing reservoir section in the Dover East 7-5-VE field. Microresistivity variations recorded by the FMS tool were converted into digital color images using standard processing parameters. At the instruction of Liberty Oil & Gas the main objective was to provide a continuous log of interpreted dip results and near-wellbore images and to answer the following: Do we see systematic trend(s) to the fracture orientation? 1 Can we determine fracture distribution and orientation (single and multi-wells)? 2 Is there a relationship between fractures orientation/density and production?
