Abstract
A low-pressure natural gas harvesting system that injects motive fluid into a first well by a compressor, which flows into a motive manifold that utilizes the Coandă effect to introduce a reduced pressure effect. The reduced pressure effect draws natural gas into the system from natural gas reservoirs through one or more inflow ports that are part of inflow manifolds, which may connect to a motive manifold. The natural gas and motive fluid mix after the motive fluid flows over a Coandă effect surface and the mixture is subsequently directed to flow to a production well.
