Summary:
An interdisciplinary seminar for all earth scientists and
engineers giving practical understanding of the principles and
interpretation of geophysical well logs in research applications.
We will meet once a week and focus on the fundamentals of well
logging methods, including electrical, nuclear, and acoustic
measurements. Discussions will involve journal readings on tool
physics and their limitations, earth science and industrial field
examples, interpretation techniques, and examples of applications
(borehole image and fracture analysis, oceanic crust
characterization, gas hydrate evaluation, cyclostratigraphy, and
others). |
| |
Format: 1 1/4 hour lectures |
| |
Time: 10 AM every Friday starting Jan. 25 |
| |
Location: Geoscience Lounge |
| |
Credit:
1 or 2 credits. Students who attend the lectures will get
1 credit. An additional credit will be given to those who read a
key paper on the subject, present it to the class, and lead a
discussion at the end of the seminar series. |

Sample well log data:
This spreadsheet (data-Excel)
contains data from a logging run of resistivity, natural
gamma ray, density, neutron, and geochemical tools. The
spreadsheet contains two pages: one has the data and the
other explains the acronyms used. For more information see
