Abstract
A setting tool for performing a wellbore operation includes a mandrel, a cylinder slidably engaged with the mandrel, and a variable volume first chamber formed between the mandrel and the cylinder and a containment member having a second chamber adjacent to the first chamber. The setting tool also includes a support fluid disposed in the first chamber, a slidable support axially and circumferentially distributed inside the first chamber, and a valve disposed between the first chamber and the second chamber. The valve is configured to flow the support fluid from the first chamber to the second chamber. The support fluid and the slidable support, support the cylinder against a downhole pressure. The setting tool is conveyed into the wellbore and connected to a consumer. The setting tool is actuated to set the consumer.
