Latest Patents
One of Dedman's latest patents is the Dual Barrier Pump-Out Plug. This invention utilizes wellbore isolation for a tubing string in a well. It features a first plug held by a temporary retention in a bore of a housing on the tubing string, sealed with a first seal. A second plug is similarly retained and sealed, creating a space between the two plugs. Both plugs can be made of a dissolvable material, with non-dissolvable coatings on specific ends.
