Embodiment Construction

[0019] figure 1 One embodiment of a multipurpose multipurpose inflation and circulation tool 100 is shown positioned within the casing section 5 . As mentioned above, the multipurpose charging and circulation tool 100 is positioned in the uppermost section of casing when the casing section 5 is run into the wellbore. The multipurpose charging and circulation tool 100 provides a channel for injecting fluid, such as drilling mud, into the casing 5 located in the wellbore. Pumping drilling mud into the casing string helps prevent casing failure caused by hydrostatic pressure outside the casing string in the wellbore. The casing string includes a float shoe (not shown) located at the bottom portion of the casing string. Floating shoes include valves, such as check valves, that prevent wellbore fluids from flowing into the casing string.

[0020] The multipurpose charging and circulation tool 100 is connectable to the wellhead-facing end of the casing section 5 that is run into ...

Abstract

A FAC tool (100) for use in a well comprising a well casing (5). The FAC tool comprises a top drive connection (10) for coupling the tool to a top drive; a push plate (30); a telescoping section (20) coupling the push plate to the top drive connection; a packer cup (50) configured to seal an annular space between the FAC tool and the well casing when the packer cup is energized; a packer element system (80) comprising at least one packer moveable between a locked position in which the at least one packer is not energized, and an energized position, the packer element system being configured to seal the annular space between the FAC tool and the well casing when in the energized position; and a slip system (70) comprising at least one slip, the slip system configured to lock the packer element in the energized position.

Description

technical field [0001] The present disclosure generally relates to a multipurpose filling and circulation tool ("FAC tool") for use in a well, and more particularly, to a multipurpose filling and circulation tool ("FAC tool") for use during high pressure conditions that includes a system of packer elements. Note and loop tools. Background technique [0002] The process of drilling a well to recover oil and gas from a hydrocarbon reservoir includes: drilling a hole in the ground to an oil accumulation; and, installing a pipeline from the reservoir to the surface. Casing is used as a protective tubular lining in the wellbore. The casing may be fed into the wellbore one section at a time. Sometimes the casing gets stuck and cannot be lowered into the wellbore. When this occurs, it is common practice to increase the load on the casing string to force the casing into the wellbore, or the drilling fluid can circulate down the inside diameter of the casing and out of the casing ...
