1. A bottom hole assembly for use within a borehole that extends into a subterranean formation, comprising a first reservoir module and a second reservoir module:
the first reservoir module including a first housing, a first low-pressure tube having an inner and outer surface, a first reservoir fluid volume disposed inside the first housing and outside the first low-pressure tube, a first high-pressure passage disposed through the first low-pressure tube, a first piston slidably sealed in the first housing and on the first low-pressure tube outer surface, the first piston exposed on a first surface to well-fluid communicated through one or more ports in the first housing and isolating the first reservoir fluid volume exposed to a second surface of the first piston;
the second reservoir module including a second housing, a second low-pressure tube having an inner and outer surface, a second reservoir fluid volume disposed inside the second housing and outside the second low-pressure tube, and a second high-pressure passage;
the first high-pressure passage fluidically connected to the second high-pressure passage;
the second reservoir module disposed to deliver the second reservoir fluid volume to the first low-pressure tube.
