Abstract
An apparatus and process for obtaining representative samples of fluids produced from one or more oil wells by means of a closed vessel chamber with lease water supply port connected to a lease water supply line, where a pressure sensor within such internal chamber is used together with a flowmeter and liquid-sensing probe or oil/water interface sensor employed in the fluid flow path lines to determine a rate of well production along with absolute or relative amounts of oil, water and gas contents. A complex and extensive distribution of fluid flowpath lines and flow control valves are employed in this well tester to achieve a multitude of process steps such as chamber filling with well fluids, chamber gas expulsion, chamber pressure measurement, chamber contents settling and stratification, gas compression, gas purging, lease water injection, chamber oil expulsion, line flushing of well fluids, air/oil interface sensing, gas/oil interface sensing, fluid flow measurement, time interval measurement and gas volume calculation via Boyle's Law by choosing a proper setting of selectable valve arrangements among a well selector valve, gas control valve, test fluid inlet valve, by-pass valve, lease water valve, purge valve and sample exit line selector valve.
