Abstract: A tool for use in a wellbore includes an annular body having an inner flow passage extending axially therethrough, at least one gripping member positioned around an outer perimeter of a retainer section of the annular body, and a gate member positioned in the inner flow passage. When the gate member is in a closed configuration, an upstream portion of the inner flow passage is sealed from a downstream portion of the inner flow passage by the gate member. When the gate member is in an open configuration, the upstream portion of the inner flow passage is fluidly connected to the downstream portion of the inner flow passage. At least one static mixing blade extends through the downstream portion of the inner flow passage to mix fluid when it flows through the open gate member.

Abstract: A method of performing an intervention operation at a multilateral well includes deploying a directional guide to an axial position within the multilateral well at which a lateral section of the multilateral well is located. The method further includes installing a main body of the directional guide to an inner surface profile arranged along a casing that surrounds the directional guide at the axial position. The method further includes closing a bore that passes through the main body along an elongate axis of the main body. The method further includes deflecting an intervention assembly along a guide surface of the main body into the lateral section. The method further includes controlling the intervention assembly to perform the intervention operation within the lateral section.

Abstract: A multilateral well access system includes a directional guide and a mating surface profile. The directional guide includes a main body and an outer surface profile disposed on the main body. The main body defines a guide surface oriented non-parallelly to an elongate axis of the main body and a bore passing through the main body along the elongate axis. The mating surface profile is formed complementary to the outer surface profile of the directional guide and is engaged with the outer surface profile to secure the directional guide in a fixed position.

Abstract: An open-channel microfluidic diode includes a first reservoir, a second reservoir, a first channel and a second channel. The first channel is in fluid communication with the first reservoir, wherein the first channel is characterized by a first cross-sectional area. The second channel is in fluid communication with the first channel and the second reservoir, wherein the second channel is characterized by a second cross-sectional area greater than the first cross-sectional area. The first channel interacts with the second channel at a junction, and wherein liquid flows from the second channel to the first channel via capillary forces.
