Abstract
The present invention relates to subterranean cementing operations, and more particularly to an apparatus useful in loading cementing plugs and darts into tubulars, and methods of using such apparatus in subterranean cementing operations. An example of a method of the present invention is a method of placing a compressible object having a cross-section within a tubular, including the steps of: reducing the cross-section of the compressible object; placing the compressible object with the reduced cross-section in a tubular; and releasing the compressible object within the tubular. Another example of a method of the present invention is a method of reducing the radial cross-section of a compressible object. Other examples of apparatus of the present invention include apparatus for placing a compressible object into a tubular.
