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.
A method of placing a compressible object having a cross-section into a tubular, comprising the steps of:
A method of reducing the cross-section of a compressible object for placement into a tubular, comprising applying a differential pressure to displace the compressible object from within a loading chamber having a first cross-section into a holding chamber having a second cross-section, wherein the loading chamber is in fluid communication with the holding chamber, wherein the first cross-section is greater than the second cross-section, and wherein the second cross-section is less than an inside cross section of the tubular, placing the holding chamber within the tubular, while the compressible object is inside the holding chamber, and releasing the compressible object into the tubular.
An apparatus for placing a compressible object into a tubular, comprising:
An apparatus for placing a compressible object into a tubular, comprising:
