Nakasawa Resources’ technology increases heat transfer to the reservoir with greater thermal efficiency, improving surface and reservoir-level steam quality, which increases crude oil mobility and therefore reservoir productivity.
Super Matroid Cyclone is the smart capsule that incorporates the latest innovation from Nakasawa Resources, an upstream technology for oil recovery optimization.
Installing Super Matroid Cyclone on your traditional OTSG will increase the profitability of the wells and will also reduce the environmental impact of the extraction process.
How does it work?
These systems can operate with high total dissolved solids (TDS) without condensed water and thermal energy loss in the saturated condensate. The 95% quality steam makes steam injection effective and very cost-effective in enhanced oil recovery (EOR) processes.
The systems consist of a high-efficiency cyclone steam separator, a set of tubes, superheater or superheater coil, mixers with automatic control valve, and a steam quality sampling system for continuous monitoring.
These processes involve controlled separation and remixing of the condensate with a sprinkler mixer operated by an automatic control valve to obtain steam qualities starting at 95%. Therefore, the process avoids loss of condensate, and the total mass goes to the system outlet and injection point.
Stages of the process:
Generation of humid steam (75% - 80%) radiant section (outlet). Similar process to a conventional generator.
The wet steam is then separated into 99% dry and saturated condensate inside the high efficiency cyclone separator. Generation of wet steam (75% - 80%) radiant section (outlet). Similar process to a conventional generator.
The dry steam is superheated in a tube bundle or superheater.
As it is a continuous generation process, the superheated steam is re-mixed with the separated condensate to achieve the desired steam dryness of 95% at the system outlet.
In this phase, there is a controlled remixing of the condensate and dry steam, so there is no loss of condensate or effluent is generated and the total mass of water leaves the system as steam with 95% dryness.
As a fundamental aspect, NAKASAWA has incorporated as an integral part of the process the monitoring of the operation parameters during the injection and post-injection stages to carry out an exhaustive control of the operations and guarantee the optimum performance of the equipment.
The automation process has several advantages where an automatic recording is made through the collection of data in real-time. The sensors record data on parameters such as pressure and temperature, fiber optics (DTS), and thermocouples to verify the progressive state of the measurement system, recording the system efficiency indicators, as well as the amplitude and phase digits. In addition to documenting sensor performance over time, potential problems can also be detected in advance.
