M-Bubble Expansion Technology

Pragma is pioneering the use of 3D metal printing in the development of an exciting range of industry leading, high expansion solutions. The M-Bubble product range is based on a novel inflatable metal element, which delivers expansion ratios far higher than is achievable using traditional manufacturing methods.

Our technology is designed to solve complex and increasingly demanding well challenges throughout the production lifecycle. The industry has been seeking stronger products, with higher expansion ratios, that are more able to operate at higher pressure for some time. To find out more download our M-Bubble brochure.

Bridge Plug

Utilising 3D metal printing, Pragma has developed the highest expansion bridge plug on the market.

Our expansion capability allows this bridge plug to pass through the smallest of well restrictions and provide downhole expansion ratios far in excess of other products. It offers unrivalled flexibility for temporary or permanent downhole isolation.

Multiple opportunities for adaptation of our extreme expansion technology, such as cement plugs and utility packer applications are also being investigated.

Thru-Tubing Expandable Patch (TEP)

Development of thru-tubing high expansion technologies in collaboration with a Middle East national oil company (NOC).

Utilising experience garnered through development of the Expansion Plug, Pragma are developing a Thru-Tubing Expandable Patch capable of industry leading expansion. For its first application in the Middle East the TEP will be used to shut off water production in barefoot open-hole wells.

The TEP will be deployed via traditional well intervention methods and be capable of shutting off water to acceptable levels to allow for oil production to recommence. Multiple TEP’s can be run to further extend the life of the well, enhance oil production and reduce capital expenditure by delaying the requirement for well recompletion or side-tracking.

Many mature wells are barefoot open-hole completions. When these wells were originally drilled they produced a high rate of oil with a low water cut, but over time oil production decreases whilst water cut increases significantly to the point where many of these wells cannot be economically produced. In many cases the source of the water cut is in the heel section of the completion with zones closer to the toe still capable of producing oil. Until this expandable patch technology was developed, typically only recompletion could reduce water cut to acceptable levels.
