Wireless casing packer

A well comprising casing and a casing packer apparatus comprising:

• a mandrel having a throughbore extending in a longitudinal direction;
• a packer element mounted on the mandrel, the packer element comprising an outer sealing face;
• a bypass conduit extending from one side of the outer sealing face to an opposite side of the outer sealing face;
• a bypass valve to control the bypass conduit;
• a wireless receiver to receive wireless signals to control the bypass valve;
• a hydrostatic setting mechanism having a member comprising a wedge portion which is fixed to, and sealed to, the mandrel;
• and
• wherein the ratio between a gauge diameter of the packer apparatus in a first position and an inner diameter of the packer apparatus in the first position is less than 1.6.
