Abstract: The systems and methods described herein relate to a high-throughput flow apparatus. The apparatus is used with an array of wells, and is configured to impart a predetermined shear stress on cells cultured within each of the wells of the array of wells. The apparatus includes a plurality of mechanical tips. The plurality of mechanical tips each includes a head with a hemispheroid shape. The apparatus also includes a motor associated with at least one of plurality of mechanical tips. The motor is configured to drive the plurality of mechanical tips to impart the shear stress pattern in each of the wells.

Abstract: A system and method of injection well identification using tracer particles is disclosed. A collector-reader for analyzing magnetic particles in a fluid that is moving with respect to the collector-reader includes an array of magnets whose magnetization direction is varied so as to create regions of high magnetic field gradient in the fluid, a stopper configured to concentrate spatially the particles attracted to the array, and a reader including a source configured to excite the particles concentrated by the stopper and a detector configured to capture a particle excitation signature emitted by the magnetic particles. A method for observing a subterranean reservoir penetrated by a production well and two or more injection wells is also disclosed.
