  • Degradable composite structures
    Patent number: 11136461
    Abstract: Embodiments may generally take the form of a degradable composite structure and a method for controlling the rate of degradation of a degradable composite structure. An example embodiment may take the form of a degradable polymer matrix composite (PMC) including a matrix having: a degradable polymer, a fiber reinforcement, and particulate fillers. The fiber loading is between approximately 10% to 70% by weight and the particulate loading is between approximately 5% to 60%.
    Type: Grant
    Filed: December 18, 2015
    Date of Patent: October 5, 2021
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Philip Kokel, Shitong S. Zhu, Matthew Godfrey, Meng Qu, Jahir A. Pabon, Yucun Lou, Francois M. Auzerais, John David Rowatt, Roman Kats, Gauri Joshi, Miranda Amarante
  • Substantially degradable perforating gun technique
    Patent number: 9926755
    Abstract: A perforating gun technique. The technique includes perforating with the gun in a manner that deforms internal support structure thereof. Thus, follow-on treatment with a breakup fluid tailored to the material of the support structure may be utilized to dissolve the structure. The carrier of the gun which houses the structure may then be utilized as a conduit for fluid flow.
