Portable, high temperature, heavy oil well test unit with automatic multi sampling system

A method of collecting hydrocarbon samples from a well, the method comprising:

• directing a fluid flow from a well into a two-phase separator;
• separating the fluid flow into a liquid stream and a vapor stream;
• extracting a first sample of the liquid stream;
• designating one of a plurality of sample collection bottles as a first sample collection bottle for receipt of the extracted first sample;
• and
• actuating a multi-position valve to direct the extracted first sample into the designated first sample collection bottle, wherein the step of designating is based on a first parameter,
• following extraction of the first sample, extracting a second sample of the liquid stream.
• designating one of a plurality of sample collection bottles as a second sample collection bottle for receipt of the second sample;
• and
• actuating the multi-position valve to direct the second sample into the designated second sample collection bottle, wherein the designated second sample collection bottle for the second sample is different than the designated first sample collection bottle wherein the first sample has a first volume and the second sample has a second volume different than the first volume.

• measuring the flow rate of the liquid stream;
• agitating the liquid stream to mix oil and water forming the liquid stream;
• and
• based on the measured flowrate, extracting the first sample of the agitated liquid stream and directing the first sample to the first sample collection bottle.
