Formation Evaluation

 

Important Notice:

The following webpages are NOT meant to be a substitute for scholarly text books on formation evaluation. These webpages are meant to help refresh your recollection of selected topics that you previously studied.

This is a work in progress! I appreciate all emails, that will help me improve these quick summary sheets.

Please send emails to dblord@petrocenter.com

Thank you,

Feteke Short Video Presentations

Fekete has 6 well testing videos: Deconvolution I and 2, Testing Tight Gas Sands, Evaluation Gas-in-Place, Well Dynamics in Well Testing.

I particularly like the deconvolution one. This is a very complex area and Louis Mattar did a great job of "making it as simple as possible, but not more so." (Einstein)
