Abstract: An antenna element receives a first radio wave and outputs a transmission signal, and receives a second radio wave and outputs a reception signal. A phase conversion unit applies a predetermined phase shift amount to a signal to be input and then output the signal. A switch connects the antenna element to one of the phase conversion unit and external receiver. When the first radio wave enters the antenna, the switch connects the antenna element to the phase conversion unit, and the transmission signal to which the predetermined phase shift amount has been applied is radiated from the antenna element. A third radio wave radiated from each of a plurality of RIS elements is deflected in a predetermined direction. When the second radio wave enters the antenna, the switch connects the antenna element to the external receiver, and the external receiver receives the reception signal.

Abstract: A subsurface representation may define subsurface configuration of a subsurface region. A grid connectivity graph for the subsurface representation may include (1) nodes that represent cells within the subsurface representation, and (2) edges between the nodes that represent connectivity between the cells within the subsurface representation. The grid connectivity graph may be filtered to remove edges that do not satisfy a connectivity criterion. The filtered grid connectivity graph may be used to compute a linear solver preconditioner that improves the performance of the subsurface simulation.

Abstract: Using a reservoir simulator, a reservoir model state is obtained. The reservoir model state is used to trace streamlines to obtain streamline trajectories and detect fluid fronts along the streamlines. Using the streamline trajectories, the streamlines are connected to wells. The streamlines are grouped for multiple granularity levels, into groups to obtain a grouping hierarchy. Through the granularity levels of the grouping hierarchy, fluid front time of flights are determined for the groups, and target flowrates assigned to completion devices based on the fluid front time of flights to obtain target flow rates. A completion design is presented that incorporates the target flowrates.
