1. A method, comprising:
encouraging a fluid sample through a conduit into a reservoir;
monitoring a pressure within the reservoir related to the encouraging the fluid sample into the reservoir as a function of time so as to generate at least a first set of pressure vs. time data;
encouraging the fluid sample out of the reservoir and monitoring a pressure within the reservoir related to the encouraging the fluid sample out of the reservoir as a function of time so as to generate a second set of pressure vs. time data, and
based at least in part on the first set of pressure vs. time data and the second set of pressure vs. time data, determining one or more of a viscosity, a viscosity as a function of shear rate, or a flow resistance of the fluid sample.
