...% of the filtrate volume was calcium-chloride brine used in the internal phase of the invert OBM. This statement leads to a conclusion that OBM and SBM formulations can potentially create in-situ emulsions in the near-wellbore flushed zone. Core flow testing at EniTechnologie demonstrated the damaging effect...

... Abstract The main objective of this study is to devise a methodology, utilizing a wealth of information gained from NMR (Nuclear Magnetic Resonance) and resistivity logs, and to assess and to quantify formation damage due to filtrate invasion in the flushed zone. Quantification of the damage...

... evaluated by utilizing a computer program where the rock formation is simulated by two-dimensional cross sections with a borehole and a flushed zone of variable thickness. Results of these numerical simulations are presented. At lower frequencies, it is shown that the mud cake effects are minimized...
