摘要： A system and method for recovery of hydrocarbon gas and liquids from a sub-sea environment utilizing a sub-sea membrane separation system. The system includes a production string located in a sub-sea wellbore for removing hydrocarbons and contaminants from a sub-sea formation. At least one membrane separator for separating contaminants from hydrocarbons removed from the sub-sea formation is located underwater between the production string and a hydrocarbon collection tank such that a predetermined temperature of the hydrocarbons is obtained by the location of the membrane. In another embodiment, a tube is connected to a sub-sea production string for removing hydrocarbons and contaminants from a sub-sea wellbore. At least one membrane separator for separating contaminants from hydrocarbons in the tube is positioned between the production string and a hydrocarbon collection tank wherein the temperature of the hydrocarbons and contaminants is controlled by the location of the membrane.

摘要： A perforation fluid is prepared having a solid material suspended in a liquid. The solid material includes particles having particle sizes that correspond to the pore throat sizes of one or more geological formations through which a well to be perforated runs. The solid material is self-degrading. Perforation of a well-casing of the well in the perforation fluid causes the solid material to instantaneously (or substantially so) form a self-degrading filter cake that facilitates setting of the final completions of the well.
