MUDLINE - MJ1
The mudline suspension system used in off-shore wells allows the casing string of an oil or gas well to be suspended and anchored directly on the seabed, transferring all the weight to the mudline. It is used in shallow waters, up to 100 meters approximately, and drilled from jack-up platforms. It is ideal for wildcat wells, as it allows for temporary abandonment and subsequent reconnection, releasing the drilling rig without leaving any installation fixed to the location. The completion can be dry, by installing a wellhead and Christmas tree on a fixed platform, or wet by using a subsea tree.
SSC COMPACT SUSPENSION SYSTEM
The SSC compact suspension system is a simplified and low-cost alternative in cases where it is not necessary to abandon the well. As with the MJ1 system, it allows the casing pipe to be anchored to the sea floor, transferring the entire weight of the casing to the mudline. It is an ingenious solution that makes the SCC a versatile and safe system ensuring a rapid and reliable operation.
