Abstract
A pressure orienting swivel arrangement includes a freely rotatable weight assembly to orient to gravity prior to being urged to a fixed position. In the fixed position, a pin adapter is reactably interengagable with the weight assembly to orient the pin adapter to the weight assembly without reorienting the weight assembly from gravity. A method for orienting a downhole tool is also included.
