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.
