  • Patent number: 10502028
    Abstract: A method includes severing a liner positioned in a first wellbore at least partially lined with casing and thereby providing a severed end, conveying a mid-completion assembly into the first wellbore and receiving the severed end within a tail pipe assembly of the mid-completion assembly, wherein a smallest inner diameter of the mid-completion assembly is greater than or equal to a smallest inner diameter of the liner and thereby permits tools sized for operations in the liner to pass through the mid-completion assembly, actuating an expandable device of the mid-completion assembly to sealingly engage an inner surface of the casing uphole from the severed end, and drilling a second wellbore extending from the first wellbore.

  • Patent number: 10347818
    Abstract: A manufacturing a process is provided for the bulk manufacture of transducer arrays, including arrays having at least one 3D printed (or otherwise additive manufactured) acoustic matching layers. In certain implementations, the manufactured transducers include a composite-piezoelectric transducer on a de-matching layer.
