Abstract
A method of drilling a wellbore may include drilling the wellbore using a wellbore fluid that has rheological property values for 6 rpm, 10 minute gel, Yield Point, and/or 10 minute-to-10 second gel ratio that are +/20% of the mean values across a temperature range from 40° F. to 300° F.; and conditioning the wellbore with less than 2 hole volumes. The wellbore fluid may include an oleaginous external phase; a non-oleaginous internal phase; an amidoamine emulsifier stabilizing the non-oleaginous internal phase within the oleaginous external phase; at least two oil wetting agents; a rheology modifier; and a weighting agent having a d50 ranging from 5 to 10 μm.
