Abstract
The present invention relates to a system and a method for detecting water break-through at an oil and/or gas production site comprising two or more oil and/or gas producing well(s) (3a) and/or well string(s) (3a). The present invention utilizes chemical in-flow tracers and allows for simultaneous monitoring of water breakthrough for two or more oil and/or gas producing well(s) (3a) and/or well completion(s) at centralized down-stream location.
Claims18
A system for detecting water breakthrough at an oil and/or gas production site comprising a) two or more oil and/or gas producing wells and/or well strings, b) two or more production tubings producing the gas and/or oil from a reservoir in a geological formation, c) two or more well-heads, d) one or more manifold(s) combining two or more flow lines, e) optionally inlets from additional production wells, f) a down-stream main production line producing the gas and/or oil from the one or more manifold(s), wherein the system comprises:
- (i) one or more tracer component(s) each comprising one or more chemical in-flow tracer(s);
- (ii) a detecting device, sampling point or sampling system for the detection of the one or more chemical in-flow tracer(s).
