1. A method comprising:
positioning a downhole acquisition tool in a wellbore in a geological formation;
operating a flow control assembly to gather information for a fluid outside of the downhole acquisition tool that enters the downhole acquisition tool from a first flowline, a second flowline, or both while the downhole acquisition tool is within the wellbore, wherein the flow control assembly comprises:
a first pump module fluidly coupled to the first flow line;
a second pump module fluidly coupled to the second flow line;
a crossover portion disposed between the first pump module and the second pump module; and
a turnaround module fluidly connected to the crossover portion, wherein the crossover portion is disposed between (i) the turnaround module and (ii) an inlet of the first flowline and an inlet of the second flowline,
wherein operating the flow control assembly comprises:
controlling a valve assembly to a first valve configuration that enables the fluid to flow into the downhole tool via the inlet of the first flowline fluidly coupled to the first pump module;
controlling a valve assembly to a second valve configuration that enables the fluid to flow into the downhole tool via the inlet of the second flowline fluidly coupled to the second pump module; and
selectively using the turnaround module, the crossover portion, or both to permit discharging the fluid from one flowline to the other flowline by actuating a valve associated with the turnaround module, by actuating a valve associated with the crossover portion, or both, and wherein the fluid flows from the inlet of the first or second flowline, through the crossover portion, through the turnaround portion, and back into the crossover portion to exit the downhole acquisition tool.
