  • Publication number: 20090205818
    Abstract: A downwell packer assembly includes a tubular member and a packer element mounted on the tubular member. The packer element comprises a composition that includes a polymer. The packer element includes micropores (typically created via a blowing agent). When the packer element is exposed to a swelling fluid, such as water or hydrocarbon, the micropores can help to control and, in some instances, increase the rate of swelling. Such swelling enables the packer element to form a seal against the walls of the wellbore.

  • Patent number: 5710108
    Abstract: The invention involves biopolymer/oil suspension compositions for the oil service industry, most particularly drilling and completion fluids, which provide such fluids a variety of desirable properties. Biopolymers include water soluble polymers and water swellable polymers. Such biopolymer/oil suspension compositions are essentially mixtures of biopolymers such as cellulosics in an oil medium with a specific anti-settling additive. The invention is particularly directed to providing enhanced anti-settling properties to such biopolymer/oil compositions; that is, the ability of the biopolymer/oil composition to retain the biopolymers in suspension prior to the composition being introduced into drilling and completion fluids. The invention in one embodiment is described as a liquid biopolymer-in-oil additive compositions for use in aqueous-based completion fluids, containing an agent comprising: a) one or more polyamides, and b) hydrogenated caster oils including castorwax.
