Abstract: A method of plugging a well extending into a hydrocarbon bearing formation fascilitates temporary or permanent abandonment of the well. The method includes detonating one or more explosive charges within a tubular or tubulars extending through the well in order to remove, fragment and or cut one or more sections of the tubulars around the entire circumference of the well to expose the surrounding formation or cement. The well is then filled in the region of the exposed surrounding formation or cement with a sealing material so as to form one or more plugs within the well to seal the well.

Abstract: A method of plugging a well extending into a hydrocarbon bearing formation facilitates temporary or permanent abandonment of the well. The method includes forming two or more plugs within the well, the plugs being formed at longitudinally spaced apart locations whilst providing a fluid communication path from a region above the topmost plug to the or each space between adjacent plugs. This configuration facilitates pressure testing of one or more of the plugs by conducting fluid through said path.
