A shoe for use with a casing string in a borehole. The shoe may include a first screen positioned within a bore of the shoe or of the casing string near the shoe. The first screen may include orifices sized to prevent the passage of lost circulation material or a material with properties similar to the lost circulation material from outside the shoe through the first screen.

Provided is a self-deflecting multilateral junction, a method, and a well system. The self-deflecting multilateral junction, in one aspect, includes a deflection device having an uphole end and a downhole end, the deflection device including a main tubular, a first flow path off the main tubular and operable to couple to a wellbore, a second flow path off the main tubular and operable to couple to a lateral wellbore, the second flow path having a lateral seal bore, and a deflecting ramp. The self-deflecting multilateral junction, according to this aspect, further includes a lateral stinger positioned within the main tubular and releasably coupled to the deflection device, the lateral stinger including a nose end configured to extend into the second flow path, a valve member, and a lateral seal for engaging the lateral seal bore.

A guide shoe (1), adapted for connection to an end of a tubular for deployment in a wellbore of an oil, gas, or water well, includes: a body (10) having an axis (2) and being adapted for connection to the tubular such that torque can be transmitted between the tubular and the body (10); a nose (50) adapted for connection to the body (10); a locking mechanism (30) adapted to shift between an unlocked configuration, in which rotation of the nose (50) around the axis of the body (10) is permitted in first and second directions, and a locked configuration in which rotation of the nose (50) around the axis of the body (10) is restricted in at least one of the first and second directions. The guide shoe includes a resilient biasing device (20) urging the nose (50) into the locked configuration.

Systems and method for providing a soft landing of a wellhead connector onto a subsea wellhead are provided. One such system includes a wellhead connector configured to be coupled to a subsea wellhead, and a soft landing system disposed on a body of the wellhead connector. The soft landing system includes one or more cylinder assemblies coupled to the body of the wellhead connector, and one or more valve assemblies coupled to the body of the wellhead connector. Each cylinder assembly includes a barrel, a rod disposed within the barrel and extending in one direction from the barrel, and a pad attached to an extended end of the rod. The one or more valve assemblies are each fluidly coupled to the one or more cylinder assemblies.

A rupture disc assembly and a float tool incorporating the rupture disc assembly is disclosed. The rupture disc assembly may include a rupture disc assembly comprising a rupture disc, an upper tubular portion and a lower tubular portion, and a securing mechanism for holding the rupture disc between the upper and lower tubular portions. A float tool for creating a buoyant chamber in a casing string may include the rupture disc assembly and a sealing device for sealing the lower end of the casing string, the buoyant, sealed chamber may be created there between. In operation, applied fluid pressure causes the rupture disc to move downward. The rupture disc may be shattered by contact with a surface on the lower tubular portion. Full casing internal diameter may be restored in the region where the rupture disc formerly sealed the casing.

A system includes a milling assembly with a mill bit and a drill string that mills a new wellbore section. The system further includes a whipstock assembly that is formed by a reamer shoe that reams an obstruction in a wellbore, a whipstock that deflects the milling assembly away from the wellbore, and a bypass valve mechanism that guides a fluid to circulate through the reamer shoe. Within the system, the milling assembly is fluidly connected to the whipstock assembly.
