Relative Permeability Measurements and Analyses for a Cluster of Fields in South Oman

During a large water flood study on a cluster of fields in<br>South Oman it became apparent that relative permeability<br>constituted one of the major uncertainties impacting<br>reserves in the cluster. At the onset of the study, only two<br>experimental measurements were available that had been<br>acquired with the currently recommended approach of<br>wettability restoration and a combination of steady state<br>and centrifuge experiments. Therefore, the team proposed<br>to core five wells and embarked on a large scale special<br>core analysis (SCAL) program, covering all predominant<br>rock types, in order to get a better handle on the relative<br>permeability characteristics.
