Welldone sir

[@sm3ool9383]

Well explained,, thank u sir

[@sulaimonrokeeb9926]

Thanks , This is helpful

[@salihaamoura232]

Thank you Dr. jurgen, Please could you send me this example of well logging record in format PDF ??

Hello sir. Good evening. The values I’m reading for Rt and Rxo at the depth of 8804 differ from what is used in the calculations

[@olugbengaolamigoke4743]

Hello Mosorire, the values for Rt and Rxo in Table 3 are read directly from the LAS file which would appear different on the plot due to probably depth shift. Secondly note that the scale should be from 0.2 to 2000 and not 200.00. I agree that the specific resistivity readings from the log should be higher than those used.

@@olugbengaolamigoke4743 Oh. Thank you very much sir. I understand now

[@بهاءاللافي-ر9ي]

I want to know an example about net sand counting

[@jalaleltabouni3810]

Hi, please when you calculate Rw did u used porosity in water zone or porosity in oil zone and what porosity neutron or density?

[@olugbengaolamigoke4743]

Porosity in the water zone is used in calculating Rw. Some use an average of the two derived porosity values.

Hello sir. Could I get this file please

[@girishsharma6871]

sir i have querry, as we know according to concept resistivity high in coal portion and low in non coal portion but due to some error its showing opposite means low in coal portion and high in non coal portion ,kindly resolve it please.

[@olugbengaolamigoke4743]

Would look at it. Thanks

[@azerallahverdi7819]

from where we get 6.77 on calculation of Rmf

[@olugbengaolamigoke4743]

Rmf = 6.77 was provided as an input. Rmf is the resistivity of the mud filtrate

[@esraahmed5773]

What can we do if we do not know the cut off vshale porosity and water saturation

[@olugbengaolamigoke4743]

Hello Esra. Cut-offs (shale volume or porosity) are set by the interpreter. It is generally recommended that a 50% shale volume be used.

Can you please give me the record of log ...with my best wishes

[@olugbengaolamigoke4743]

Hi. The well log is from the book: Basic Well Logging and Formation Evaluation @ bookboon.com

[@soufianelaouici8551]

try to go to the point , you talk a lot without saying anything , i couldnt complete the explanation , sorry

[@olugbengaolamigoke4743]

Well noted. Thank you. Is there any specific aspect you need clarification on?
