Abstract
Interventionless setting assemblies and associated methods are disclosed. A method of setting downhole equipment comprises applying a pressure to a compensating volume and providing a working volume, wherein the working volume is separated from the compensating volume by one or more hydraulic control devices. A pressure is applied to the working volume in response to the pressure applied to the compensating volume. The pressure applied to the compensating volume is then reduced and the pressure applied to the working volume is captured by maintaining the pressure applied to the working volume when the pressure applied to the compensating volume is reduced. The captured pressure in the working volume is applied to set downhole equipment.
