Tracking feedstock production with micro scale gas-to-liquid units

A method of utilizing production from a NG source, the method comprising:

• providing one or more micro-scale GTL units each individually having a gas feed rate ranging from about 200 to about 1,000 thousand standard cubic feet per day and production rate from about 20 to about 100 bbl liquid per day , with a combined gas feed rate matching the production from the NG source;
• feeding natural gas from the NG source to the one or more micro-scale GTL units and operating the one or more micro-scale GTL units over a period of time in which the production from the NG source changes;
• and
• adjusting the number of micro-scale GTL units employed so as to match the combined gas feed rate to changed production from the NG source;
• wherein the micro-scale GTL units are dimensioned to be transportable independently of each other as units within the dimensions of a shipping container sized module of 8 ft×10 ft×40 ft.
