Super Matroid Cyclone, an upstream technology for oil recovery optimization, is a smart capsule that incorporates the latest innovation from Nakasawa Resources.

Installing Super Matroid Cyclone on your traditional OTSG will increase the profitability of wells and will also reduce the environmental impact of the extraction process.

HOW DOES IT WORK?

This technology allows for increased heat transfer to the reservoir and greater thermal efficiency, improving surface- and reservoir-level steam quality to increase reservoir productivity.

These systems can operate with feedwater with high total dissolved solids (TDS) without losing water condensate or thermal energy in the saturated condensate. A steam quality of 95% makes steam injection efficient and very profitable in enhanced oil recovery (EOR) processes.

These systems consist of a high- efficiency cyclone steam separator; a tube assembly, superheater or superheater coil; mixers with automatic control valves; and a steam quality sampling system for continuous monitoring.

Nakasawa’s SMH and SMC processes involve controlled condensate separation and remixing with a sprinkler mixer, all operated by an automatic control valve to obtain a steam quality of at least 95%. This means there is no loss of condensate, and the total mass goes to the system outlet and injection point.

STAGES OF THE PROCESS:

A-B-C-D-1-2-3

The SMH or SMC follows a process similar to that of a conventional generator. In this stage, wet steam is generated (75% - 80%), with a radiant section (outlet).

E-4

The wet steam is separated into more than 99% dry steam and saturated condensate inside the high-efficiency cyclone separator.

F-5

The dry steam is superheated in a tube assembly or superheater.

G-H-6

Finally, because it is a continuous generation process, the superheated steam is once more mixed with the separated condensate to achieve the desired 95% dry steam at the system outlet. Streams G and H correspond to the steam injection lines leading to the well head and steam venting, respectively. In this phase, controlled condensate remixes are performed to ensure there is no condensate lost or effluent generated; the total mass goes to the system outlet. It is important to highlight that no extra solids or incrustations are generated throughout the entire process.
