An unmanned aerial vehicle (UAV) autonomously perching on a curved surface from a starting position is provided. The UAV includes: a 3D depth camera configured to capture and output 3D point clouds of scenes from the UAV including the curved surface; a 2D LIDAR system configured to capture and output 2D slices of the scenes; and a control circuit. The control circuit is configured to: control the depth camera and the LIDAR system to capture the 3D point clouds and the 2D slices, respectively, of the scenes; input the captured 3D point clouds from the depth camera and the captured 2D slices from the LIDAR system; autonomously detect and localize the curved surface using the captured 3D point clouds and 2D slices; and autonomously direct the UAV from the starting position to a landing position on the curved surface based on the autonomous detection and localization of the curved surface.

Dynamic pressure wave propagation can be used in pipelines to provide information about the available, unobstructed diameter and any partial or complete blockages in the pipeline. Certain aspects and features can be used to locate a pipeline inspection gauge (pig) that may be deployed in the pipeline, since in terms of a pressure profile, the pig is no different than any other type of pipeline blockage. Regular pulsing of the pipeline with a pressure wave can further be used to track a blockage over time. A valve or any other suitable device such as an air gun can be used to generate the pressure wave. A time series analysis can be carried out to determine and track the location of the blockage.

An apparatus to distribute pressurized fluid from one or more sources to multiple wellbores. The apparatus includes a manifold having at least two inlets and at least two outlets. Pressurized fluid is brought into the manifold from opposing directions so that the fluid from one inlet will impinge upon the fluid from the other inlet thereby de-energizing the fluid. Additionally, the manifold is configured such that the cross-sectional area of the inlets is less than the cross-sectional area of the manifold thereby decreasing velocity minimizing the kinetic energy available to erode or otherwise damage equipment, while providing a pressure decrease as the fluid enters the manifold. The outlets are configured such that the cross-sectional area of the outlets providing fluid to a single wellbore is greater than or equal to the cross-sectional area of the inlets such that no pressure increase occurs within the manifold or the outlets as the fluid exits the manifold. Additional velocity reduction enhancements may include angled or camp third turns between the inlet and the manifold or the manifold and an outlet.
