Systems and method for separating hydrocarbon fluids from water and solid material within a main tubular of a subterranean well include locating a transducer assembly within the subterranean well, the transducer assembly including a plurality of piezo electric transducers spaced along a length of the main tubular. Standing acoustic waves are generated with the plurality of piezo electric transducers, the standing acoustic waves passing through the main tubular transverse to the central axis. A number of loops of the standing acoustic waves decrease in a direction of flow of fluids through the main tubular.

Acoustic downhole oil-water separation

A method and system for treating a hydrocarbon-bearing reservoir with a DOWS system includes forming a first and a second DOWS system wells that fluidly communicate with both a first and second hydrocarbon-bearing formation. The first well has an upflowing DOWS unit and the second well has a downflowing DOWS unit. The DOWS units separate production fluid into a water-rich fluid and a hydrocarbon-rich fluid that passes to the surface. Both wells have an injection zone and a production zone. The DOWS system is operated such that water-rich fluid from the first DOWS well is introduced into the first hydrocarbon-bearing formation, water-rich fluid from the second DOWS well is introduced into the second hydrocarbon-bearing formation, production fluid from the second hydrocarbon-bearing formation is introduced into the first DOWS well, and production fluid from the first hydrocarbon-bearing formation is introduced into the second DOWS well.
