  • Patent number: 12065761
    Abstract: Methods of preparing a mineral-coated rock micromodel can include 3D-printing a transparent porous micromodel with photo-curable polymer, seeding a thin layer of mineral nanoparticles in the network of pores inside the micromodel, and subsequently growing a mineral layer on the thin layer of mineral nanoparticles. The thin layer of mineral nanoparticles can be introduced by injecting a suspension containing the mineral nanoparticles through the microporous polymer micromodel, and the mineral layer can be grown in-situ on the thin layer of mineral nanoparticles in the network of pores by injecting an ion-rich solution configured to crystallize from solution in response to contacting the mineral nanoparticles.

  • Patent number: 12049040
    Abstract: Three-dimensional printing on a membrane of a filtration device is described herein. Forming the filtration device involves receiving a membrane comprising a porous material, depositing an ink into pores of the porous material, causing the ink to solidify, and continuously building three-dimensional printed structures via micro-stereolithographic three-dimensional printing. Solidifying the ink causes the ink to bond with the membrane.

  • Publication number: 20240012174
    Abstract: Methods and systems are disclosed to determine a permeability value and a permeability image of a rock. The process can include determining labeling of a 3D segment of a rock. The labeled segments can be determined using, for example, computer vision and machine learning and can be used to determine a grain size of a 3D rock segments. The grain size value can be used to determine a permeability value for the 3D rock segment. The permeability value of the 3D rock segment can be used to determine the heterogeneous permeability of the rock.

  • Patent number: 10518194
    Abstract: In an improved fiber-film type contactor/separator an enhanced coalescing zone is provided by the presence of a disengagement device connected to a shroud that contains a bundle of high surface area vertical hanging fibers, where the enhanced coalescing zone diverts a portion of an admixture of immiscible liquids to flow radially in a path not parallel to the vertical axis of the hanging fibers whereby the diverted portion of liquids contacts a coalescing surface to cause at least one of the liquids to coalesce into droplets. The immiscible liquids are allowed to settle into separate phase layers and first and second outlets selectively remove the higher density liquid from the lower density liquid.
