Abstract
A hydraulic connection mechanism for use in a wellbore comprises an upper connection tool, a lower connection tool configured to engage the upper connection tool and form a fluid communication pathway through the hydraulic connection mechanism, and a debris barrier disposed in the fluid communication pathway. The debris barrier comprises a body element, and a spring element configured to maintain the body element in a closed position when the upper connection tool is disengaged from the lower connection tool.
Claims21
A hydraulic connection mechanism for use in a wellbore comprising:
- an upper connection tool;
- a lower connection tool configured to engage the upper connection tool and form a fluid communication pathway through the hydraulic connection mechanism;
- and
- a debris barrier disposed in the fluid communication pathway, wherein the debris barrier comprises:
- a body element;
- and
- a spring element configured to maintain the body element in a closed position when the upper connection tool is disengaged from the lower connection tool.
A method of servicing a wellbore comprising:
- providing a hydraulic connection mechanism within a wellbore, wherein the hydraulic connection mechanism comprises:
- an upper connection tool;
- a lower connection tool engaging the upper connection tool, wherein a fluid communication pathway is formed through the hydraulic connection mechanism when the upper connection tool engages the lower connection tool;
- and
- a debris barrier disposed in the fluid communication pathway;
- disengaging the upper connection tool from the lower connection tool;
- allowing the debris barrier to close off the fluid communication pathway;
- re-engaging the upper connection tool with the lower connection tool;
- and
- actuating the debris barrier to establish fluid communication through the fluid communication pathway.
A method of actuating a debris barrier comprising:
- providing a debris barrier disposed in a fluid communication pathway within a lower connection tool within a wellbore;
- engaging an upper connection tool with the lower connection tool;
- actuating the debris barrier to displace a portion of a fluid in the fluid communication pathway;
- and
- establishing fluid communication between the upper connection tool and the lower connection tool through the fluid communication pathway comprising the debris barrier.
