Since majority of the conventional logging tools were developed for vertical wells, they deliver less-than-optimal results for highly deviated and horizontal wells. Flow regimes in downhole conditions, especially in highly deviated and horizontal wells can be very complex (Bahrami et al, 2010; Schlumberger flow scanner brochure, 2006) Downhole flow regimes especially in case of multiphase flows in highly deviated and horizontal boreholes include, stratification, wavy, annular (Segregated) distributed and slug (intermittent); distributed and bubble (misting) along with recirculation (Bahrami et al, 2010). The problem of logging will typically occur when conventional tools run in deviated wells encounters such flows traveling at different speeds, e.g. bubbly flow, heavy phase recirculation, or stratified layers.
