Sonic Petrophysics

By May 18, 2014Workshops

Date: Sunday May 18, 2014
Time: 8:00 AM – 5:00 PM
Place: Capital Suite – ADNEC
Instructors: Bern Herold, Petrophysical Advisor (Cairn India Ltd), Jean Marrauld, Senior Geophysicist (ADMA), Tad Smith (Apache Corporation),  Matt Blyth (Schlumberger)

This course is intended to provide an introduction to the role of sonic measurements in Petrophysical analysis and will explore the use of sonic measurements for a variety of applications. It will cover the basics of borehole sonic measurements and processing on both wireline and LWD devices, including monopole, dipole, quadrupole and Stoneley modes and the answers that can be obtained from each and the range of applicability of the measurements in both open and cased hole. It will explore the use of these sonic measurements in Petrophysical and Geophysical applications including porosity estimation, fluid typing/gas identification, pore pressure prediction, fracture identification, permeability estimation, synthetic seismic generation, AVO, etc. The links to elasticity and rock mechanics will be shown along with the applications in drilling and well bore stability. In addition there will be discussion on acoustic anisotropy and its importance, particularly when considering unconventional reservoirs. Throughout the course both class and small group worked examples will be used to show the importance of sonic measurements to understanding and solving these problems, what measurements are needed and why and the limitations of the analysis.
