Methods and systems are provided for producing hydrocarbons from production fluids that have water as an external phase. A method for transporting a hydrocarbon through a pipeline includes injecting water into a production stream at a production center. The production stream includes a hydrocarbon, and the water injection forms a transportation stream that includes a water external phase. The transportation stream is flowed through a transportation line to a surface facility, wherein the transportation line comprises a plurality of static mixers spaced at intervals along the transportation line.
