Synchronised system for the production of crude oil by means of in-situ combustion

Abstract

A synchronized crude oil production system using in-situ combustion that measures, monitors, and controls the operating conditions in real time. The system includes at least one injection well, at least one production well, and at least one inclined synchronization well. The end of the production well(s) and the end of the inclined synchronization well(s) within the reservoir are oriented outward the injection well and the wells include measurement, monitoring, and control elements. The measurement and monitoring elements transmit signals and data collected to one or more processing units which, together or independently, use an analytical model to assess the combustion conditions in the well-subsurface system and the forward move of the combustion front and, depending on the results, synchronize the production operations. Each well being operated and handled remotely at the control valves thereof in order to influence the displacement direction of the combustion front.
