Abstract: A balanced piston toe sleeve allows a pressure test cycle to be carried out before opening the bore of the toe sleeve to the wellbore. The balanced piston toe sleeve includes a valve assembly in which a valve piston separates a valve cylinder into a balancing cylinder and an actuation cylinder. The actuation cylinder is coupled to the bore through a check valve which allows unidirectional flow into the actuation cylinder. The balancing cylinder is in fluid communication with the bore. After a pressure test cycle, the pressure in the balancing cylinder reduces, while the pressure in the actuation cylinder is retained by the check valve. The valve piston shifts into the open position, allowing fluid flow from the bore to the toe sleeve.

Abstract: A swellable packer which includes a generally tubular mandrel having a central axis and an exterior cylindrical surface. The swellable packer further includes a swellable elastomeric body fixed to the exterior cylindrical surface of the mandrel, wherein the swellable elastomeric body includes a plurality of grooves and wherein the generally tubular elastomeric sleeve has a circumference and a thickness.

Abstract: A valve collar for use with a fluid actuated downhole tool includes a mandrel having one or more valve cylinders formed in the wall thereof, the valve cylinders formed at an angle to the mandrel. The valve cylinders may be connected to each other, to the interior of the mandrel, and to the fluid actuated downhole tool through end holes, slant shell holes, and radial holes. Each valve cylinder may include a valve assembly inserted thereinto.

Abstract: A downhole packer element includes an inner and outer cable wrapped layer positioned about an inflatable bladder. The inner and outer cable wrapped layers are formed from helically wrapped, parallel cables. The inner cable wrapped layer may be wrapped about a layer of slats.
