Challenge: Increase production by converting an existing slanted well into a horizontal well by geosteering in a structurally uncertain zone
Solution:
Perform sidetrack operation and optimize geosteering by deploying a BHA consisting of
- GeoSphere 475 reservoir mapping-while-drilling service to identify structural changes
- PowerDrive Orbit rotary steerable system to accurately control trajectory
- SonicScope multipole sonic-while-drilling service to assess permeability and identify open and closed fractures
- MicroScope resistivity- and imaging-while-drilling service to provide resistivity data and identify structural dip, fractures, and faults
- Petrel E&P software platform to evaluate structural complexity using3D visualizations
Results:
Achieved geosteering objectives by accurately drilling the well using GeoSphere 475 service for the first time, which provided real-time reservoir data from a 22-m [72-ft] depth of investigation around the wellbore
