Abstract: A method for flow manipulation within a porous volume. Steps include inducing a sequence of fluid flows between fluid sources and fluid sinks disposed at at least three spaced locations in or around a porous volume, the fluid flows being induced by providing fluid at one or more of the sources and extracting fluid at one or more of the sinks. Successive fluid flows in the sequence are induced at predetermined times and oriented in different directional orientations between different sources and sinks, the successive fluid flows define different flow volumes which at least partially intersect one another, and the successive fluid flows are selected to induce cross-directional flows to mix one or more fluids in the porous volume.

Abstract: Described embodiments relate to methods, systems and infrastructure for flow manipulation within a porous volume. Some embodiments relate to a method of subsurface flow manipulation, comprising: providing fluid at a first subsurface location adjacent to or in a subsurface volume through which the fluid is to pass; providing first suction at a second subsurface location adjacent to or in the subsurface volume to extract fluid from the subsurface volume, the second subsurface location being located across at least part of the subsurface volume from the first subsurface location; providing fluid at a third subsurface location spaced from the first subsurface location and adjacent to or in the subsurface volume; and providing second suction at the first, second or a fourth subsurface location adjacent to the subsurface volume to extract fluid from the subsurface volume.
