Magnetic Susceptibility Measurements of Offshore Carbonate Samples

Abstract

Magnetic susceptibility measurements were made on 84 samples from offshore carbonate cores for Applied Reservoir Technology Ltd. Samples that had been soaked in a brine were first cleaned before being sent to NGU for the suscepti- bility measurements. Samples that had a residue of brine with high salt concentration could have a higher susceptibility value than reported here since a salt residue would contribute a negative (diamagnetic signal). All measured samples had low to negative susceptibilities.
