Abstract
Official abstract text for this publication.
A pressure relief valve system for use in a downhole operation may include a pressure relief valve configured to relieve pressure from high pressure tubing extending between a pump and a wellhead, and may include a sensor operably disposed to detect pressure in the high pressure tubing. The pressure relief valve system also may include a controller having a pressure threshold stored therein. The controller may be configured to receive data from the sensor and compare the detected pressure to the stored pressure threshold. A valve actuation system may be in communication with the pressure relief valve and in communication with the controller. The valve actuation system may be configured to change the state of the pressure relief valve from a closed state to an open state in response to a command signal from the controller.
