20100234253 | Method for reducing the viscosity of viscous fluids - 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 and said material is optionally cross-linked. In one embodiment, the formulation may comprise polyvinyl alcohol. In an alternative embodiment, the formulation may comprise a cross-linked polymeric material, such as cross-linked polyvinyl alcohol. After the viscous composition has been transported to a desired location, it may be separated from the other components. | 09-16-2010 |
20080314415 | Cleaning Contaminated Materials - Oil contaminated drill cuttings are contacted with an oil soluble surfactant with agitation which causes the hydrophobic moiety of the surfactant to interact with the oil. Next, an aqueous polymer formulation comprising a polymer having polar and/or ionic functionality is added and mixed. Then, an excess volume of water is added with gentle agitation and the mixture is allowed to settle, whereupon the cuttings sediment to the bottom of the receptacle in which the process is undertaken and the supernatant contains a colloidal suspension of particles which comprise oil, surfactant and polymer. The drill cuttings may then be separated from the supernatant by filtration. The supernatant may be treated with a flocculating agent to cause the colloidal particles to sediment. They too may then be separated. | 12-25-2008 |
