Dispersing Separated Hydrocarbon Gas into Separated Oil During Surface Well Testing for Improved Oil Mobility

A method for improving oil mobility during surface well testing, the method comprising:

• producing a multiphase fluid from a well;
• separating a gas constituent and an oil constituent having an undesirable viscosity from the multiphase fluid in a separator;
• measuring the gas constituent and the oil constituent;
• injecting at least a first portion of the gas constituent into the oil constituent upstream of a centrifugal pump;
• mixing the first portion of the gas constituent with the oil constituent in the centrifugal pump to disperse the first portion of the gas constituent into the oil constituent and form an oil/gas mixture having a viscosity that is lower than the undesirable viscosity of the oil constituent;
• and
• burning the oil/gas mixture at an oil burner.

A method for improving combustion efficiency of oil during surface well testing, the method comprising:

• producing a multiphase fluid from a well;
• separating a gas constituent and an oil constituent from the multiphase fluid in a separator;
• measuring the gas constituent and the oil constituent;
• injecting at least a first portion of the gas constituent into the oil constituent;
• dispersing the first portion of the gas constituent into the oil constituent to form an oil/gas mixture;
• and
• burning the oil/gas mixture at an oil burner.
