Abstract
A method of determining a concentration of a component in a flow from a single source or layer contributing to a total flow is described using the steps of repeatedly changing the relative flows from the source; and for each of the changed relative flows determining the combined flow rate and a total concentration of the component of the total flow until sufficient data points are collected to solving a system of mass balance equations representing the flow of the component from each source at each of the changed flow rates.
Claims14
A method of determining relative contributions of two or more subterranean sources to a total flow, the method comprising the steps of
- repeatedly changing the relative flow rates from said producing sources;
- and
- for each changed flow rate measuring the total flow rate and a total concentration of one or more flow components used as geomarkers within said total flow, until sufficient measurements are made to solve a system of mass balance equations representing a flow of said one or more flow components from each of such layers at each of said changed relative flow rates.
