Abstract
A high temperature downhole packer including a tubular member, an annular and longitudinally movable ring, and a packer. The tubular member has a stop located on an outer diameter thereof. The annular and longitudinally movable ring is disposed around the outer diameter of the tubular member. The packer element is disposed between the stop and the ring. The packer element includes a high temperature elastomeric polymer having a first storage modulus from about 1,000 MPa to about 10,000 MPa at a first temperature between about −100° C. and about 175° C., and a second storage modulus from about 1 MPa to about 1000 MPa at a second temperature ranging from about 175° C. to about 475° C.
