WIM LOOYESTIJN

Since my retirement from Shell mid 2012, I offer my expertise on a consultancy basis. My distinguishing skills are in accurate modeling of the in-situ NMR log response, incorporating specific properties of the fluids and wettability... I am a professional researcher with more than 40 years' experience. My main topic has become interpretation of NMR core and log data on which I became an internationally acknowledged expert. I pioneered in utilizing diffusion effects to discriminate oil from water, leading to Shell's NMR processing package MacNMR, which set a standard in the Industry. Other developments include derivation of capcurves from NMR, and, more recently, wettability and modeling of in-situ NMR log response... Wim Looyestijn offers consulting services for interpretation of NMR (nuclear magnetic resonance) logs. His speciality is response modeling at reservoir conditions.
