UHX M-Bubble Bridge Plug delivers outstanding 266% expansion, enabling successful water shut-off in a subsea LWI project.

DTI's UHX M-Bubble technology has delivered an outstanding 266% downhole expansion rate, enabling successful water shut-off in a subsea light well intervention project.

An international operator was experiencing increased water cut from a subsea well in the North Sea and had embarked on a production enhancement programme to remedy the issue. Following the acquisition of PLT logging data, the decision was made to isolate a lower section of the well and re-perforate above. The intervention would be performed from a light well intervention vessel using cable deployment.

For this application, a high expansion plug was required to navigate a 3.256” restriction in the upper completion and set in a 7”, 32 lb/ft liner, at a deviation of 5°, holding a differential of 1,800 psi from below, with a well temperature of 110°C.

DTI's UHX M-Bubble Bridge Plug delivered successful isolation and water shut-off which was verified in a later PLT logging run.
