METHOD FOR REDUCING THE VISCOSITY OF VISCOUS FLUIDS |
摘要 |
<p>A viscous fluid, such as heavy crude oil which is too viscous to enable it to be pumped from a flowing phase of a reservoir into and along a pipeline for delivery to a refinery or other storage facility, may be contacted with a formulation to reduce its viscosity. The formulation comprises a polymeric material AA which includes -O- moieties pendent from a polymeric backbone thereof. In one embodiment, the formulation may comprise polyvinyl alcohol. After the viscous composition has been transported to a desired location, it may be separated from the other components.</p> |
