  • Patent number: 11041117
    Abstract: A polymer-encapsulated mineral acid solution and a method for forming the polymer-encapsulated mineral acid solution. Introducing a strong mineral acid solution to a monomer solution occurs such that a primary emulsion that is a water-in-oil type emulsion forms. Introducing the primary emulsion to a second aqueous solution forms a secondary emulsion that is a water-in-oil-in-water type double emulsion. The monomer in the secondary emulsion is cured such a polymerized shell forms that encapsulates the strong mineral acid solution and forms the capsule. The strong mineral acid solution has up to 30 wt. % strong mineral acid. A method of stimulating a hydrocarbon-bearing formation using the polymer-encapsulated mineral acid solution includes introducing a capsule suspension into a fissure in the hydrocarbon-bearing formation to be stimulated through a face in a well bore. The capsule is maintained within the fissure until the polymer shell degrades.

  • Publication number: 20090079056
    Abstract: An electronic package and methods by which the package reduces thermal fatigue failure of conductors in the electronic package. The electronic package includes a carrier substrate having first and second surfaces and a plurality of anchor vias having a via material extending from the first surface toward the second surface. The electronic package includes a first conducting layer having a length and a width extending laterally in two dimensions across a major part of the first surface of the carrier substrate. The anchor vias have plural attachments along the length and the width of the first conducting layer to secure the first conducting layer to the carrier substrate.
