Enhanced LWD Fluid Sampling Mobility via PAD Orientation Optimization Based On Azimuthal LWD Measurements

Newly developed oriented LWD FTS is tested and implemented in operations to effectively sample formation fluid in challenging conditions such as unstable borehole or formations with complex reservoir heterogeneity. A spot with a sampling fluid mobility was excessively higher than that of a spot selected randomly by the conventional blind orientation; significantly reduced the total pump-out time for sampling which is especially important for unstable borehole conditions.
