ABSTRACT:
Systems and methods for recovering power fluid from a device under water and for pumping recovered power fluid to a surface of the water, the systems and methods, in certain aspects, including: flowing fluid from a subsurface apparatus to a subsurface recovery system, the fluid initially provided to the subsurface apparatus to power the subsurface apparatus; and the subsurface recovery system including pump apparatus for selectively pumping recovered fluid to a fluid container above a surface of the water. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).
