摘要： Disclosed herein is a swellable packer having a support element. A portion of the support element is substantially adjacent to the base tubular. Another portion of the support element is separated from the base tubular and a portion of the area between the support element and the base tubular is filled with the swellable material. Also disclosed herein is a sealing system including a packer as described above and a method for sealing within a wellbore using a packer as describe above.

摘要： A sealing member. The sealing member can include a support member having an inner bore and a plurality of apertures formed therethrough. An outer swellable element can be disposed about an outer diameter of the support member, and an inner swellable element can be disposed about an inner diameter of the support member. The swellable elements can be unitized with one another through each aperture. A retainer can be disposed at each end of the support member.

摘要： The present invention provides an apparatus capable of influencing explosive energy during wellbore applications. In one embodiment, a cap or other interfering element may be arranged proximate to an explosive charge prior to detonation. The size and positioning of the element with respect to the explosive charge may be manipulated to achieve an optimum explosive orientation. A ring element having a bore therethrough may be utilized for directing the explosive energy of the charge upon detonation.
