George Asks PERM: Dear PERM, I read a paper you co-authored with Taqa, SCA2015-020, and I wonder if you have any experience with running NMR logs on Montney cores post-Dean Stark cleaning. I found your conclusion interesting that there was a material amount of water left in the core after the Dean Stark cleaning process [...]
Muhammed Asks PERM: Dear PERM, When a wetting phase is displacing a non wetting phase, snapping off occurs as the potential gradient in the wetting phase across the flow segment is lower than the capillary pressure across the same flow segment; I can't understand how can capillary pressure oppose the flow of a wetting phase; [...]
Yaho Asks PERM: Dear PERM, I want to know something about the semi-permeable diaphragm method especially about the wetting and the non-wetting fluid. Based on my knowledge in the case of gas/water system, just the nitrogen is used to apply pressure on oil to displace water out the rock sample and a semi-permeable membrane or [...]
Muhammed Asks PERM: Dear sir, When displacing oil by water in a water wet reservoir, why does the interfacial tension increase when the oil thread gets smaller? Thank you, Muhammed Dr. Jonathan Bryan from PERM Answers: Hello Muhammed, Interfacial tension is the force that has to be overcome to change the interfacial area between two [...]
Zulq Asks PERM: Hello, I have run samples for Resistivity Index and got a lot of inconsistent data for the 'n' values. The data does not make sense. We have re-run samples and got different data that also confuses the situation. We would appreciate if you could advise us on possible solutions? Thank you, Zulq [...]
Prachi Asks PERM: Hello, In hydraulic fracturing why it is preferable to use high capillary number in oil recovery system? Why it is preferable to decrease surface tension rather than increase in velocity? Thank you, Prachi Dr. Jonathan Bryan from PERM Answers: Hi Prachi, Thanks for your question. During hydraulic fracturing, the objective of the [...]
Jeremie Asks PERM: Hello, I have one question regarding the Dean Stark Analysis for my oil sands core. After the analysis, can I get the clean sand, and the oil and the water, so I can perform measurements on them? Or do we loose some fluids in the process? Thank you, Jeremie Dr. Jonathan Bryan [...]
Michael Asks PERM: Hello, I have 2 questions: I have chosen to quarry and core my rock samples to a dimension of 10inches in length and 1.5inches in diameter for my flow experiment. But many research workers have used dimensions smaller than mine most frequently they have used 6inches in length and 1.5inches in diameter. [...]
Yordi Asks PERM: Hello, In this moment we have many problems with properties of fluid because the oils have high viscosity (4000 to 10000 cP at Temperature of reservoir). All equations of viscosity have two parameters (density or API and Temperature) For example the correlation Beal This correlation has application in light oils but in [...]
Fahad Asks PERM: Hello, Thanks for your assistance, my question is, how can we generate a relative permeability curve during laboratory core flooding tests. Suppose I want to see the effect of nanofluids in altering my core wettability, how can I generate the relative curves for both the base fluid (brine alone) and the nanofluids [...]
