Well Log Interpretation Review Ab

[@ethan7702]

Thank you so much Fred. I am doing my logging analysis course and I understood that how to read the R0 and Rt from the track after your explain. It is very formative and priceless. Thank you and appreciate it.

[@eslam_edrees]

I need the courses of logging analysis can you help me!!?

[@dona6920]

I Found the Basic Evaluation of South Louisiana well log presentation to be very helpful. Fred Thurber has demonstrated great mastery of the subject and presented the interpretation in a professional manner. There are a lot of things i did not get from class that after listening to the video they became very clear. I wish Fred will continue to post more videos of log interpretation as well as those from other disciplines in Petroleum Engineering. Thanks once more Mr. Fred Thurber.

[@jiperez1901691]

I am a drilling engineer, this explanation is excellent. thanks a lot.

[@rahulbaliyan9402]

Excellent explanation, in a very simple way. Thank you so much Fred!

[@sureshkumar-gy1ye]

Excellent presentation. Thank you Mr. Fred Thurber.

[@kolaonifade3268]

Excellent video. Simply and straight to the point. Thanks

[@walisardar446]

Excellent, It helped me to prepare a bit for exam tomorrow, Do we have more videos like this

[@JYamo216]

Amazing! I get one question, how does wireline group do the depth correction job? Use CCL or GR or both CCL+GR?

[@96068646]

thank you for this awesome video! Really wish you could post more. Was definitely helpful for me

[@tarunmalhotra2751]

Hello We provide well log digitizing services at reasonable price. We can convert your well logs into LAS 2.0. You need not to do anything just send us scanned copy of logs. My email id is [e-mail]

[@oluwatomilayoojo2154]

please do more videos. you are such a great teacher

[@jeremiah7167]

Hi sir. In well logging technology, what are the two main interpretation problems?

[@NajamTameem29]

Very informative. excellent presentation. Thanks a lot for uploading.

[@DrStoneDog]

Interval transit time (or delta-t) is high in shale. It's the inverse of velocity. True, shales don't have much porosity, but the clay minerals that comprise them are very slow minerals (meaning, they have a high delta-t). Therefore, when delta-t is used to compute porosity in shales, it will overestimate the true porosity. Same is true in shaley rocks.

[@junebacandido1947]

so what do I use for computing porosity in shales that is reliable??

[@bbbbssss7868]

Thanks for video! very useful and important information.

[@pinkmath8466]

Thank you for posting! This def. cleared a few things up for me, it was very straight forward.

[@yuewang9623]

Thank you. This video is so educative and straightforward.

[@giocondatovar2023]

Very good explanation. Thank you for sharing.

[@MrSaidi03]

Thanks Fred for posting.Good explanation

[@asadzaman4318]

teacher if for the zone 1 water saturation is 10% so why we cant produce oil because its less then the 39% of water saturation. because the density of the first zone is occupied by hydrocarbons and the pressure of the zone 1 hydrocarbons does not gain water saturation of the zone 2 i mean the the down side of the reserviour so the zone 1 will push up by itself because of its pressure. hopefully you will answer of my question Thanks

[@muhammadarshadrashid6264]

Excellent demo and masterly interpretated

[@hernandosuasti9412]

I am a mechanical engineer and I do.understand this thank you

[@learningtogether6414]

Hi Thank you for the videos. Do you know about a well log called I6FR, any paper that you can recommend about this? Thank you

[@JuanCarlos-eq2mo]

Any current textbook that might help me to get the basic concepts for water well applications? I am on my own and new to this topic. I hold a Physics BS. Please help. Intend to buy textbook and learn it on my own. Thank you.

[@jervizeloy]

Great video. Do you have some others to share with us?

[@geology3217]

Could you make a video about well log and interpret depositional environment?

[@reagankabogozza1132]

Great Vid but never use the SP log as your shale volume indicator (lithology) unless you are 100% sure that you do not have HC in your formation. HC damps the SP curve . And also the best matrix travel times for matrix are from your petrophyscist's core plugs tests.

[@gruud6700]

Great video! I was taught the best method to determine porosity is to read half way between the density porosity and neutron porosity curves. Interestingly, you will see that method yields ~26% porosity for the target zone, which is what he calculated with the transit times (showing that both methods work well).

[@eslam_edrees]

Can you Tel my how did you that!!!

[@gruud6700]

@@eslam_edrees Reading the values at 10260 feet depth in the liquid zone, the neutron and density curves overlap around 26% porosity (therefore, their halfway point is 26%). You get a similar answer in the gas cap at 10250 feet where the neutron reads at 38%, and the density reads 15%, so the halfway point is 26.5%. However, for neutron-density porosity calculations in the gas cap, you should use following formula for more accurate porosity: square root of (((density porosity squared) + (neutron porosity squared))/2) or in other words, φformation = ((φDensity^2 + φNeutron^2)/2 )^0.5. Plugging in the porosity values from 10250 feet, I calculate 28.9% porosity.

[@josefreja7649]

thank you so much for this video,, I have one question,, How can we determine the Zone of interest? I am still confusing because if we choose base on the top and the bottom of Sandstone, we also have another sandstone below our current zone of interest?? thank you in advance for your explanation,,

[@mirandabrooks8043]

the zone of interest has higher resistivity. Therefore it most likely is hydrocarbons. I am sure in the nature of time he abbreviated some of the lesson

[@maryf3730]

Hello! Thank you very much for your video! Excuse me I have a question, Can somebody help me please? I didn't understand how he knew the value of the R0?

[@kershhall2946]

From the deep induction curve. He found where he assumed was a homogeneous sand and found the lowest point on the interval

[@kuzman39]

this video is well detailed, i have a question, can you use the gamma ray log alone for Determination of Lithology

[@tshegokhati9795]

yes you can

[@aqeelsultan970]

It's difficult to determine lithology with GR only . You got high GR in shale generally but its possible to get high GR with argillsious limestone and coal

[@borimapa]

Hello, @ 18: 24, did you say that transit time reads high in shales? I think it is the reverse. Is it a mistake?

[@TheTaboy82]

Do you have a NFR in dolomites or carbonates presentation?

[@RonPaulCurrency]

good video, i've been waiting on some well logging videos. also helps its from louisiana

[@andriyadipaembonan753]

Fred Thurber, do you have a reference (book or journal) explain the equation in your video?

[@andriyadipaembonan7304]

@BBShale Thanks

[@samermohammed296]

can you please explain why you considered Sw=(Ro/Rw)^1/2 ? my understanding Archie equitation is phiSw=(Ro/Rt)^1l2

[@JimmyTheGreek2000]

Actually Sw=Sqrt of Ro/Rt or Sw=sqrtFxRw/Rt Therefore, we can re-write the equation as: Sw=(Ro/Rw)^1/2 Sqrt= the square root F=Ro/Rw or F=a/phi^m (m is the cementation exponent which is = 2; However, m can range from 1.8 to 2.2)

[@christophersamuel6016]

thank you for that beautiful lecture.

[@hiteshkumarr20]

hello sir, i want some help to extract data from coal well-logging...my whatsaap number 03322637991

[@Gin2Kiii]

Thank you for this video. I have a question regarding resistivity, the deep readings are always for Ro or Rxo? And shallow(focused) are always for Rt?

[@milosmilankovic2963]

I enjoy listening you suffer while giving this lecture! Really relaxing :)

[@migueleduardosanmartinsuar5719]

Thank you for the video, I have a question, I got an excercise at school which consists in: measuring the Saturation only with SP and a NL, is that possible, by using asumptions? How?

[@ola...o1009]

Thank you 😊

Thanks well done

[@SuperYeiso]

excellent tnhx for the video

[@CrossTimberRanches]

are you saying "Mud Logging" is useless?????

[@mirandabrooks8043]

I hope he isn't saying that!

[@ShravaneeSingha]

Xcellent Xplanation

[@Catalin40Ro]

Excellent.

[@ahmedadnanaziz2005]

thank you very much

[@naveed461]

EXCELLENT...

[@CHASSEP1]

Hello, it is a mistake, because interval transit time is not high in shale. When interval transit time increase, porosity increase therefore we know that we are in sandstone zone. thanks

[@gruud6700]

Shale has very high porosity (but very low permeability, of course), therefore interval transit time should increase.
