Abstract
A hydraulic connection mechanism for use in a wellbore comprises an upper connection running tool, a lower connection tool configured to engage the upper connection running 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 running tool is disengaged from the lower connection tool.
Claims19
A hydraulic connection mechanism for use in a wellbore comprising:
- an upper connection tool comprising a first flow line;
- a lower connection tool comprising a second flow line and a circumferential groove, wherein the second flow line is in fluid communication with the circumferential groove, and wherein the lower connection tool is configured to releasably engage the upper connection tool and form a fluid communication pathway through the hydraulic connection mechanism between the first flow line and the second flow line through the circumferential groove;
- and
- a debris barrier disposed at least partially within the circumferential groove 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 comprising a circumferential groove, wherein the lower connection tool releasably engages the upper connection tool, wherein a fluid communication pathway is formed through the circumferential groove in the hydraulic connection mechanism when the upper connection tool engages the lower connection tool;
- and
- a debris barrier disposed at least partially within the circumferential groove 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, wherein the debris barrier is at least partially disposed within a circumferential groove in the lower connection tool;
- 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 circumferential groove in the fluid communication pathway comprising the debris barrier.
