  • Pressurized flotation for tubular installation in wellbores
    Patent number: 11125044
    Abstract: An apparatus includes a tubular, a base, and a float shoe. The base includes a first sealing member and a flow control device. The first sealing member is configured to prevent fluid flow into and out of the inner volume of the tubular up to a first pressure differential value. The first sealing member is configured to rupture when exposed to a pressure differential that is at least equal to the first pressure differential value. The flow control device is configured to allow fluid to enter the inner volume and prevent fluid from exiting the inner volume through the flow control device. The float shoe includes a second sealing member configured to prevent fluid flow into and out of the inner volume up to a second pressure differential value and configured to rupture when exposed to a pressure differential that is at least equal to the second pressure differential value.
