Summary
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.
