Abstract
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.
Claims10
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.
1 more element
A seat arrangement comprising:
- a pusher;
- a cone having a tapered face with an angle relative to a cone longitudinal axis of about 10 degrees or less;
- and
- a seal having a seal deformation face configured to contact the tapered face.
1 more element
A method for creating a seat in a borehole comprising:
- running to a selected location in a borehole a seat arrangement including a pusher, a cone having a tapered face with an angle relative to a longitudinal axis of the cone of about 10 degrees or less, and a seal having a seal deformation face having a similar angle relative to the cone longitudinal axis and configured to interact with the tapered face;
- shortening a run-in length of the combination of the pusher and the cone;
- and
- radially deforming the seal.

A method for fracturing a borehole comprising:
- running to a selected location in a borehole a seat arrangement including a pusher, a cone having a tapered face with an angle relative to a longitudinal axis of the cone of about 10 degrees or less, and a seal having a seal deformation face having a similar angle relative to the cone longitudinal axis and configured to interact with the tapered face;
- shortening a run-in length of the combination of the pusher and the cone;
- and
- radially deforming the seal;
- sealing the seat with a plug;
- and
- pressuring against the plug and seat to initiate a fracture in a formation defining the borehole.
