Demulsifier analysis framework

A system comprising:

• a tensiometer, configured to:
• measure an oil and water field sample that comprises an added candidate demulsifier;
• generate tensiometer data based on measuring of the oil and water field sample that comprises the added candidate demulsifier;
• and
• transmit the tensiometer data from the tensiometer to a demulsifier analysis framework;
• a processor;
• memory operatively coupled to the processor;
• and
• processor-executable instructions stored in the memory to instruct the system to:
• receive the tensiometer data for the oil and water field sample that comprises the added candidate demulsifier, wherein the tensiometer data comprise rheology data with respect to frequency;
• determine a performance characteristic for the added candidate demulsifier with respect to the oil and water field sample, without performance of a bottle test for the oil and water field sample, using the tensiometer data as input to a model derived at least in part on bottle test data for demulsifiers in oil and water emulsions;
• and
• output the performance characteristic for the added candidate demulsifier with respect to the oil and water field sample.

One or more computer-readable storage media comprising processor-executable instructions to instruct a computing system to:

• receive tensiometer data for an oil and water field sample that comprises an added candidate demulsifier from a tensiometer configured to measure the oil and water field sample that comprises the added candidate demulsifier and generate the tensiometer data based on measuring of the oil and water field sample that comprises the added candidate demulsifier, wherein the tensiometer data comprise rheology data with respect to frequency;
• determine a performance characteristic for the added candidate demulsifier with respect to the oil and water field sample, without performance of a bottle test for the oil and water field sample, using the tensiometer data as input to a model derived at least in part on bottle test data for demulsifiers in oil and water emulsions;
• and
• output the performance characteristic for the added candidate demulsifier with respect to the oil and water field sample.
