10. A coreflood system, comprising:
a housing including an inlet end and an outlet end;
an inlet coupled to the housing and positioned at the inlet end;
an outlet coupled to the housing and positioned at the outlet end;
two chambers positioned within the housing between the inlet and the outlet, each chamber retaining porous media,
wherein the porous media has a length of up to 20 inches and a diameter of up to 1.5 inches,
wherein the two chambers are in series along a fluid flow pathway through the coreflood system, and
wherein the two chambers prevent fluid bypass around the porous media;
a partition, comprising a partition gap in the partition, coupled to an inner surface of the housing and positioned between the inlet and the outlet, wherein the fluid flow pathway is disposed through the partition gap;
wherein the partition has a height of from 0.1 to 3 inches that protrudes from the inner surface of the housing inward, and wherein the partition has a width of from 1 to 3 inches;
a calcium ion sensor and a sensor mounting location in the housing to define access via the calcium ion sensor,
wherein the calcium ion sensor is coupled to the sensor mounting location with access to the fluid flow pathway; and
a data processing device,
wherein the coreflood system is configured to pass fluid through the inlet and through the housing.
