Abstract
Provided herein are portable apparatus as well as methods of analyzing a fluid using these portable apparatus. In some embodiments, the injection fluid can contain a polymer, but a polymer is not necessary. For example, the portable apparatus and methods may be used to determine viscosity, long term injectivity, filter ratio, or any combination thereof of the injection fluid. Advantageously, the surrogate core is temperature controlled.
