<p>A method for reducing the aqueous content of oil-based drilling fluid includes contacting an invert emulsion wellbore fluid with a water absorbing polymer, interacting the water absorbing polymer with the wellbore fluid for a sufficient period of time so that the water absorbing polymer absorbs at least a portion of the aqueous fluid form the wellbore fluid; and separating the water absorbing polymer containing the absorbed water from the wellbore fluid.</p> |
