Abstract
Official abstract text for this publication.
A degradable seat arrangement consisting of a pusher; a cone having a tapered face; and a seal having a seal deformation face configured to contact the tapered face. A method for creating a seat in a borehole.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for creating a seat in a borehole comprising: shortening a run-in length of a combination consisting of a pusher and a cone having a seat, and a seal, the pusher being radially unaltered during the shortening, the cone having a tapered face with an angle relative to a longitudinal axis of the cone of about 10 degrees or less, and the seal having a seal deformation face having a similar angle relative to the cone longitudinal axis and configured to interact with the tapered face, the arrangement positioned at a predetermined borehole location; and radially deforming the seal by the shortening to seal and anchor with the borehole. 2. A method for fracturing a borehole comprising: shortening a run-in length of a combination consisting of a pusher and a cone having a seat, and a seal, the pusher being radially unaltered during the shortening, the cone having a tapered face with an angle relative to a longitudinal axis of the cone of about 10 degrees or less, and the seal having a seal deformation face having a similar angle relative to the cone longitudinal axis and configured to interact with the tapered face, the arrangement positioned at a predetermined borehole location; and radially deforming the seal by the shortening to seal and anchor with the borehole; sealing the seat with a plug; and pressuring against the plug and seat to initiate a fracture in a formation defining the borehole. 3. The method as claimed in claim 2 further comprising degrading the seat arrangement. 4. The method as claimed in claim 2 further including degrading the plug.
