Introduction to Core Log Integration, Part 4: PGE358 Spring 2020
PGE358, Spring 2020: Principles of Formation Evaluation.
Instructor: Carlos Torres-Verdin, PhD, Professor, Hildebrand Department of Petroleum and Geosystems Engineering, The University of Texas at Austin.
This video-recorded lecture is an introduction to the integration of well logs and core samples/data. Part 1 introduces the objectives of core-log integration with special emphasis on (a) the limitations of well logs and core samples, and (b) the complementary nature of well logs and core samples, especially in the context of larger-scale geophysical or reservoir studies. Part 2 exemplifies the integration of core samples/data and well logs for the case of a turbidite sedimentary sequence (clastic sedimentary environment). Part 3 considers the specific case of a Permian carbonate sedimentary sequence. Finally, Part 4 (this video) walks through an example of core-log integration in the Eagle Ford shale.

Thanks a lot! I enjoy watching your lectures!
Thank you! How I can get PGE358 well-log compendium?
This is really helpful. Thank you so much
This x-ray movie of flow thorugh carbonates vs. berea sandstone is one of the most astonishing things I've ever seen in petroleum engineering. It really makes you wonder about the efficiency and accuracy of the estimation of original oil in place through volumetric methods, and its recovery factor in these carbonate sequences. This is why I am still a fierce defender of material balance methods for reserves estimation.
I was strucked to see Sr (strontium) in minute 43:40 when the diagenisis of dolomite is explained. Usually we focus on Mg, but Sr is there too, and Sr and Lithium seem to be correlated in carbonate systems. Maybe the presence of Sr in these rocks can explain the existence of high values of Lithium in some places (maybe not).
pg 23 has a good unconventional target given that Hc saturated zone.
Great videos Dr. Nice video series. Please, keep them coming.
Thanks lot! Very useful!
Thank you professor, I am currently doing petrophysical analysis of a gas-condensate well whose rp35 lies between tight and conventional. This is a superb video!
very interesing topic . I found this video when try to find any explanation about thomas stieber method.
Excellent Professor!!!
Professor sir your classes are interesting and more practical orientations for understood beginners
Thank you so much...you made SP very plattable... Now I am hooked i will watch all your vedios! Amazing prof!!
Nice material. Can be those shaly sands huge continuous bodies? Or can be pockets? Have you seen these shaly bodies response (oil yearly decline) with small values (16-18 % yearly) or higher (35-45% yearly)? Thanks
depends on porosity distribution, cementation history, shale distribution and the kind of deposit it is. Grain size, porosity, etc vary with flow regime types, which expresses differently over fans, sheets, or channels.
They can be isolated bodies or continuous. Both exist. If there is a steep decline its due to a smaller reservoir, or reservoir damage from overpumping, connate water, etc.... a flat decline indicates a larger reservoir as well as a potential horizontal target if the decline becomes flat but consistent, then the drainage area is large.
Another important point he made was around 23 minutes in about vertical communication in reservoirs. Fractures and faults will cause formation offsets as well as voids and breaks in the thin bedded barriers which can help with more lateral communication by connecting smaller and/or thinner lenses or beds with adjacent beds to add areal extent. Porosity also might be high enough that it all communicates, and that does vary with volume %shale. A rapid decline can mean a formation is tight, small, or damaged (often by overproduction). When scouting, youre always looking for areas with flat declines and decent volumes for horizontal plays...
Many thanks to Dr. Charles. One question, why are the stylolites wavy in shales whereas they are sutured in carbonates?
What is the explanation of the shale at 24.24 and 27.10? How/what can make him come there?
Thanks for the video. One question, if this is a gas well why don’t we see the neutron log shooting to the right and the density to the left?
Thanks a lot. Great explanation
Great lecture! muchas gracias for sharing it professor.
THANKS
Great lecture, can anyone help me in identifying the salinity of water from sp log. Please
This initiative is so great Dr. Torres-Verdin. I really appreciate all your efforts to share a bit of your knowledge through this platform. I guess it is like attending to your lectures from the comfort of our houses and in our spare time. Thanks again!! I am really enjoying this

Dear Carlos. I used to work at Petrobras, We met each other at Cartagena, SPWLA. I enjoyed a lot your class here. I m retired from Petrobras but I am a professor at UFBA Brasil, Bahia. I teach Sedimentology, Petroleum Geology and Formation Evaluation or Logging Open Holes. I have a Canal at You tube in Portuguese. Geologia do Petróleo por Roberto Rosa.
