  • Publication number: 20190250514
    Abstract: A method for fabricating calcite channels in a nanofluidic device is described. A photoresist is coated on a substrate, and a portion of the photoresist is then exposed to a beam of electrons in a channel pattern. The exposed portion of the photoresist is developed to form a channel pattern, and calcite is deposited in the channel pattern using a calcite precursor gas. The deposited calcite includes at least one side having a length in a range of approximately 50 to 100 nanometers. The photoresist remaining after developing the exposed portion of the photoresist is removed.

  • Publication number: 20190249512
    Abstract: Methods and systems for isolating a loss circulation zone of a subterranean formation includes lowering a drill string having a tubular member from a surface into a subterranean well and securing a packer assembly to the tubular member, the packer assembly having an inflatable packer unit and a protective sleeve. The protective sleeve is in an extended position and circumscribes the inflatable packer unit and the inflatable packer unit is in a deflated condition. A stabilizer body is secured to the tubular member downhole of the packer assembly. The stabilizer body is shaped to centralize the packer assembly and direct debris traveling uphole in a direction radially outward of the packer assembly. The protective sleeve is moved from the extended position to a retracted position. The inflatable packer unit is inflated to an inflated condition, forming a seal with an inner diameter surface of the subterranean uphole of the loss circulation zone.

  • Patent number: 10378298
    Abstract: An unbalanced sub-assembly includes a turbine and a shaft coupled to the turbine at a first end of the shaft. The unbalanced sub-assembly is capable of rotating and imparting a vibration to the casing in response to a fluid being passed through the casing. A rupture disc is positioned on one end of the unbalanced sub assembly. The rupture disc is configured to rupture above a specified differential pressure threshold caused by fluid flowing through the vibration assembly. The rupture disc is capable of allowing the fluid to bypass the unbalanced sub assembly when the rupture disc is in a ruptured state. The rupture disc directs fluid through the unbalanced sub assembly when the rupture disc is in an un-ruptured state.

  • Patent number: 10378462
    Abstract: A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate. The condensing takes place through heat exchange between the onboard fuel and the vaporized adsorbate that are present within the various compartments of the supply tank.

  • Patent number: 10379248
    Abstract: Example computer-implemented methods, computer-readable media, and computer systems are described for accurate localization of wireless sensor devices in underground oil reservoirs. In some aspects, every sensor measures respective received magnetic field strengths (RMFSs) on a plurality of respective magnetic induction (MI) links and transmits the measured respective RMFSs to at least one anchor devices. A set of distances is determined from the measured respective RMFSs. The set of distances is processed through an ordered sequence of algorithms, namely weighted maximum likelihood estimation (WMLE), semi-definite programming (SDP) relaxation, alternating direction augmented Lagrangian method (ADM), and conjugate gradient algorithm (CGA), to generate accurate localization of the wireless sensor devices in underground oil reservoirs.
