MICP & Permeability Question?

Stephen Asks PERM: Hello, When conducting MICP analysis, I had always assumed that mercury was the non-wetting phase and air was the wetting phase.  However, it the sample is evacuated of air prior to mercury injection, what is the wetting phase? If the relative permeability to mercury (or HC) is zero at 100% saturation of the [...]

Can two fluids of differing densities mix in porous media?

Fran Asks PERM: Hello, I've been out of school for 40 years but once thought I knew a lot about MVTs (Mississippi Valley Type Lead/Zinc Deposits). We operated under a hypothesis that two fluids were involved: a metalliferous basinal brine and a sulphurous trap in a dolostone 'reef'. However we were constrained to believe that two [...]

Understanding Wettability Testing Issues for Carbonate and Shale Reservoirs?

Sanja Asks PERM: Hello, I would like to have better understanding on contact angle and wetting properties for both shale and carbonate reservoirs. I am a little unfamiliar with the testing. Can you please advise? Thank you, Sanja Dr. Jonathan Bryan from PERM Answers: Hi Sanja, To get wettability data we can run several different tests. [...]

What method of normalization for NMR spectra do you use?

Diana Asks PERM: Hello, Currently, I've been doing experimental tests in low field NMR , and I read in the majority of your papers that in order to negate the effect of differences in amplitude due to sample mass, you apply normalization and I´d like to know which normalization method is the best for this spectra? [...]

NMR as a tool for measuring Pore Throat Sizes?

Sergiy Asks PERM: Hello, Pore Throat Sizes with NMR -- How small can you measure? Thank you, Sergiy Dr. Jonathan Bryan from PERM Answers: Hi Sergiy, NMR as a tool gives a better measure of pore body size compared to pore throats, because it is giving the response of fluids and fluids are in the pore [...]

Calibrating NMR Logs when you have an Irregular Borehole and used a Centralized Tool?

Glenn Asks PERM: Hello, When doing a downhole NMR log, how do you calibrate with an irregular borehole if you used a centralized tool where it is in the center of the borehole? Or is that data no good and you must use a sidewall NMR log? Thank you, Glenn Dr. Jonathan Bryan from PERM Answers: [...]

What is the residual oil saturation for water flooding vs immiscible gas flooding? | Ask PERM

Amir Asks PERM: Hi there, If you flood two identical cores (let's say with poro=25%, perm=200 md) one with water and another one with immiscible gas (like associated gas), for which case do you expect a higher residual oil saturation? Thanks, Amir   Dr. Jonathan Bryan from PERM Answers: Hello, Let’s start by assuming that [...]
