Abstract

A method includes providing a hydraulic connector having a hydraulic lock, wherein the hydraulic lock is operated using a hydraulic supply line and a hydraulic outlet line, and connecting the hydraulic connector to a component by activating the hydraulic lock. While the hydraulic lock is activated, a connection between the hydraulic connector and the component is pressure tested by directing a portion of the hydraulic fluid from the hydraulic supply line to a pressure testing system, using an intensifier in the pressure testing system to pressurize the portion of hydraulic fluid to a testing pressure, and directing the pressurized portion of hydraulic fluid to the connection to test a pressure rating of the connection.

First claim

What is claimed:

1 . A system, comprising:
a hydraulic connector comprising a hydraulic lock; a hydraulic supply line and a hydraulic outlet line fluidly connected to the hydraulic lock; a test port in fluid communication with a connection surface of the hydraulic connector; an intensifier fluidly connected to the test port; a pressure transducer fluidly connected between the intensifier and the test port; and a manifold, comprising:
a test supply line fluidly connecting the hydraulic supply line to a test port of the intensifier,
a test control valve positioned along the test supply line,
a bleed supply line fluidly connecting the hydraulic supply line to a bleed port of the intensifier,
a bleed control valve positioned along the bleed supply line,
a bleed outlet line fluidly connecting the test control valve to the hydraulic outlet line, and
a one way valve positioned along the bleed outlet line, and
wherein the manifold fluidly connects the intensifier to the hydraulic supply line and the hydraulic outlet line.

2 . The system of claim 1 , wherein the bleed outlet line also fluidly connects the bleed control valve to the hydraulic outlet line.

3 . The system of claim 1 , further comprising:
a master control unit, wherein the master control unit is in communication with the bleed control valve and the test control valve; and a valve operable to control flow from a hydraulic fluid source to the hydraulic supply line, wherein the master control unit is in communication with the valve.

4 . The system of claim 1 , a valve control package comprising at least one valve fluidly connected to the hydraulic supply line and the hydraulic outlet line.

5 . The system of claim 1 , wherein the hydraulic connector is hydraulically locked onto a fracturing tree.

6 . The system of claim 1 , wherein the intensifier and the manifold are coupled to the hydraulic connector.

7 . The system of claim 1 , wherein the intensifier and the manifold are positioned a distance away from the hydraulic connector, outside of a redzone boundary.

8 . The system of claim 1 , wherein the intensifier is coupled to the hydraulic connector and the manifold is positioned a distance away from the hydraulic connector, outside of a redzone boundary.

9 . The system of claim 1 , further comprising one or more seals positioned around the connection surface.

10 . The system of claim 1 , wherein the test port is in fluid communication with the connection surface via a test port flow path formed through the hydraulic connector.
