WORKSHOP 5: Introduction to Borehole Image Logs from Acquisition to Interpretation
INSTRUCTORS: Bernd Ruehlicke, Bastian Roters, Susana Gutierrez Carrilero, Shim Yen Han (Yenny), Chandramani Shrivastava and Peter Barrett
Date: Sunday, June 11, 2023
Time: 8:00 am – 4:30 pm
Fee: $375.00 for registered attendees; $475.00 non-registered (includes lunch)
Maximum Capacity: 50
Course Summary: This workshop is designed to introduce the functionality of borehole hole image log data. Participants will acquire knowledge on how to use this data for the description of stratigraphic and structural features as well in-situ stress related features in vertical and horizontal wells. The workshop will describe the acquisition of data, QC and most common pitfalls and will discuss real life examples from the field.
Expectations: Participants should leave this workshop with a good understanding about the functionality and analysis of borehole image log data.
Topic Outline
- Welcome + previous BHI experiences in the group
- What are BHI’s (types, muds, WL/LWD)
- BHI interpretation potentials and which BHI is best to deliver answers for a given question
- Acquisition
- Quality Control
- Feature detection – live “picking” exercise
- BHI application in HA/HZ wells.
- Pitfalls vertical wells vs horizontal wells vs LWD
- Attendees present/discuss some of their exercises
Who Should Attend?
This workshop is primarily aimed for Petrophysicists, geologists, geophysicists, and team members involved in reservoir characterization.
Prerequisites
A basic understanding of geology, petrophysics and geomechanics
