The linear wellhead connection system uses linear movement of an inlet conduit to transition between multiple discharge conduits that are connected to different wellheads to pump pressurized fluid from a manifold to the different wellheads. The inlet conduit is moveable in a linear direction along a track system relative to the discharge conduits. ## Claims ### Claim 1 A linear wellhead connection system, comprising: a plurality of discharge conduits, wherein each discharge conduit is fluidly coupled to at least one wellhead, and wherein each discharge conduit has a receiver; an inlet conduit, wherein the inlet conduit has a connection member engageable with the receiver on each discharge conduit to fluidly couple the inlet conduit to the discharge conduit, and wherein the inlet conduit is moveable relative to each discharge conduit in a linear direction to engage and disengage the connection member of the inlet conduit to and from the receiver of any one of the discharge conduits; a track system, wherein the inlet conduit is movable along the track system in the linear direction to engage and disengage the connection member to and from the receiver of any one of the discharge conduits; at least one of a flexible hose and a rotatable joint fluidly coupled to the inlet conduit, wherein the at least one of the flexible hose and the rotatable joint remains coupled to the inlet conduit when the inlet conduit moves in the linear direction; and a pressurized fluid source fluidly coupled to the inlet conduit to supply pressurized fluid. ### Claim 2 (depends on 1) The linear wellhead connection system of claim 1, wherein the inlet conduit is moveable along a primary track of the track system laterally relative to the discharge conduits, and wherein the inlet conduit is moveable along a secondary track of the track system toward and away from the discharge conduits. ### Claim 3 (depends on 2) The linear wellhead connection system of claim 2, wherein the at least one of the flexible hose and the rotatable joint remains coupled to the inlet conduit as the inlet conduit moves along the primary and secondary tracks of the track system. ### Claim 4 (depends on 1) The linear wellhead connection system of claim 1, further comprising a drive system configured to move the inlet conduit, wherein the drive system is directly or indirectly coupled to the inlet conduit. ### Claim 5 (depends on 1) The linear wellhead connection system of claim 1, further comprising a frame, wherein the discharge conduits and the inlet conduit are supported on the frame and movable together as a single unit. ### Claim 6 (depends on 1) The linear wellhead connection system of claim 1, further comprising a plug handling system configured to remove a plug member from each discharge conduit. ### Claim 7 (depends on 1) The linear wellhead connection system of claim 1, wherein the connection member of the inlet conduit and the receiver of the discharge conduits comprise an electric, hydraulic, or manual coupling system. ### Claim 8 A linear wellhead connection system, comprising: a plurality of discharge conduits, wherein each discharge conduit is fluidly coupled to at least one wellhead, and wherein each discharge conduit has a receiver; an inlet conduit, wherein the inlet conduit has a connection member engageable with the receiver on each discharge conduit to fluidly couple the inlet conduit to the discharge conduit, and wherein the discharge conduits are moveable relative to the inlet conduit in a linear direction to engage and disengage the connection member of the inlet conduit to and from the receiver of any one of the discharge conduits; at least one of a flexible hose and a rotatable joint fluidly coupled to the discharge conduits, wherein the at least one of the flexible hose and the rotatable joint remains coupled to each discharge conduit when the discharge conduit moves in the linear direction; and a pressurized fluid source fluidly coupled to the inlet conduit to supply pressurized fluid. ### Claim 9 (depends on 8) The linear wellhead connection system of claim 8, further comprising a track system, wherein the discharge conduits are movable along the track system in the linear direction to engage and disengage the receiver to and from the connection member of the inlet conduit. ### Claim 10 (depends on 9) The linear wellhead connection system of claim 9, wherein the at least one of the flexible hose and the rotatable joint is fluidly coupled to each discharge conduit to direct pressurized fluid to each wellhead, wherein the at least one of the flexible hose and the rotatable joint remains coupled to each discharge conduit as the discharge conduit moves along the track system. ### Claim 11 A method of pumping fluid into a plurality of wellheads, comprising: moving an inlet conduit linearly along a track system and laterally relative to a plurality of discharge conduits, wherein at least one of a flexible hose and a rotatable joint remains fluidly coupled to the inlet conduit as the inlet conduit moves along the track system; engaging a connection member of the inlet conduit with a receiver of a first discharge conduit of the plurality of discharge conduits to fluidly couple the inlet conduit with the first discharge conduit; and pumping pressurized fluid through the at least one of the flexible hose and the rotatable joint, as well as through the inlet conduit and the first discharge conduit, and into a first wellhead that is fluidly coupled to the first discharge conduit. ### Claim 12 (depends on 11) The method of claim 11, further comprising: disengaging the connection member of the inlet conduit with the receiver of the first discharge conduit to de-couple the inlet conduit from the first discharge conduit; moving the inlet conduit linearly along the track system and away from the first discharge conduit of the plurality of discharge conduits; then moving the inlet conduit linearly along the track system and laterally relative to the plurality of discharge conduits; and moving the inlet conduit linearly along the track system and toward a second discharge conduit of the plurality of discharge conduits. ### Claim 13 (depends on 12) The method of claim 12, further comprising: engaging the connection member of the inlet conduit with a receiver of the second discharge conduit to fluidly coupled the inlet conduit with the second discharge conduit; and pumping pressurized fluid through the at least one of the flexible hose and the rotatable joint, as well as through the inlet conduit and the second discharge conduit, and into a second wellhead that is fluidly coupled to the second discharge conduit. ### Claim 14 (depends on 11) The method of claim 11, wherein the inlet conduit moves linearly along a primary track of the track system and laterally relative to the plurality of discharge conduits, and wherein the inlet conduit moves linearly along a secondary track of the track system and toward the first discharge conduit of the plurality of discharge conduits. ### Claim 15 (depends on 14) The method of claim 14, further comprising moving the inlet conduit along the primary and secondary tracks of the track system by a drive system that is coupled directly or indirectly to the inlet conduit. ### Claim 16 (depends on 11) The method of claim 11, further comprising pumping pressurized fluid through both of the flexible hose and the rotatable joint, wherein the rotatable joint is fluidly coupled to a pressurized fluid source, and wherein one end of the flexible hose is fluidly coupled to the rotatable joint and an opposite end of the flexible hose is fluidly coupled to the inlet conduit. ### Claim 17 (depends on 11) The method of claim 11, further comprising a frame, wherein the discharge conduits, the track system, and the inlet conduit are supported on the frame and movable together as a single unit. ### Claim 18 (depends on 11) The method of claim 11, wherein the discharge conduits are fluidly coupled to at least one wellhead by one or more flexible hoses, one or more hard pipes, or a combination thereof. ### Claim 19 (depends on 11) The method of claim 11, wherein the connection member of the inlet conduit and the receiver of the discharge conduits comprise an electric, hydraulic, or manual coupling system.
