Today’s Patent – Multi Plug System

The said invention (US11814926B2) was invented by Andres Sosa, patented by USPTO on 30-11-2021. Currently, it stands assigned to Baker Hughes Oilfield Operations LLC.

In the resource recovery and fluid sequestration industries, plugs are often set in a borehole in order to perform downhole operations. In various plug systems, the plug is set via a rotation of the plug once it is at its target location downhole. Setting multiple plugs can require multiple trips downhole, which is both time-consuming and expensive. Attempts to set two or more plugs in a single trip is hindered by rigid connection between plugs. Thus, once a lower plug is set, the plugs above it are prevented from being able to rotate to set itself in the borehole.

There is therefore a need to be able to set multiple plugs downhole in a single trip that allows flexibility of rotation between the plugs. An assembly and a method of setting a plug in a borehole. The assembly includes a first lock, a second lock axially separated from the first lock. The plug is located between the first lock and the second lock. A bore of the assembly passes through the first lock, the second lock and the plug. A ball is dropped through the bore and activates the first lock and the second lock to allow the plug to rotate into a set configuration in the borehole.
