Abstract
A fluid management system for controlling fluid flow at a wellbore includes a closing element formed complementary to a drill pipe disposed within the wellbore and an activation system. The activation system is configured to move the closing element into an activated position against the drill pipe to close the wellbore around the drill pipe for preventing fluid from flowing out of the wellbore. The activation system includes an activation shaft coupled to the closing element and a rotatable drive shaft configured to cause translation of the activation shaft to push the closing element into the activated position against the drill pipe.

A fluid management system for controlling fluid flow at a wellbore, the fluid management system comprising:
- a closing element formed complementary to a drill pipe disposed within the wellbore;
- an activation system configured to move the closing element into an activated position against the drill pipe to close the wellbore around the drill pipe for preventing fluid from flowing out of the wellbore, the activation system comprising:
- an activation shaft coupled to the closing element, and
- a rotatable drive shaft configured to cause translation of the activation shaft to push the closing element into the activated position against the drill pipe.
A method of controlling fluid flow at a wellbore, the method comprising:
- providing a closing element of a fluid management system at the wellbore, the closing element being formed complementary to a drill pipe disposed within the wellbore;
- rotating a drive shaft of an activation system of the fluid management system;
- translating an activation shaft of the activation system, the activation shaft being coupled to the drive shaft and to the closing element;
- and
- pushing the closing element into an activated position against the drill pipe to close the wellbore around the drill pipe for preventing fluid from flowing out of the wellbore.
