Abstract
A method for removing water from a wellbore fluid may include the steps of contacting a wellbore fluid with a water absorbing polymer, where the wellbore fluid includes an aqueous fluid, allowing the water absorbing polymer to interact with the wellbore fluid for a sufficient period of time so that the water absorbing polymer absorbs at least a portion of water in the aqueous fluid, and separating the water absorbing polymer containing the absorbed water from the wellbore fluid.
