The global trend toward environmentalism has created a growing need for sustainable, cost-effective EOR solutions that can help companies maintain their social license to operate, but few solutions yet satisfy these demands.
Nakasawa Resources found an efficient, profitable solution for thermal EOR (TEOR) in heavy crude oil wells with its Super Matroid Heater (SMH) and Super Matroid Cyclone (SMC), which significantly enhance oil recovery from existing wells. Both were designed with a strong emphasis on efficiency, because Nakasawa Resources believes a “waste not, want not” attitude will be key to ensuring a future for the oil and gas industry, especially as drilling new wells becomes increasingly unpopular among public opinion.
The SMH and SMC leverage their highly efficient steam production technology to significantly boost oil recovery, greatly reduce feedwater usage, increase heat transmission and minimize operating time, all of which work together to maximize profits. Automation and digitization also play an important role here, allowing users to monitor variables and execute commands remotely and in real time through a centralized panel as well as providing the system with the ability to make immediate adjustments to ensure no time goes to waste.
Furthermore, the solutions are designed to be highly corrosion-resistant (using a chrome and molybdenum alloy) and fully mobile, making them much hardier and easier to move between injection points or over roads—another important aspect for enhancing sustainability, as it prevents the need for costly construction and removal projects.
The SMH and SMC’s results have shown a 315% increase in oil production for wells using this technology. Its high-quality steam (over 95% dry) enhances heat transfer and helps extract every drop of oil available in a well. As there are millions of barrels of oil left in existing wells that have historically been unreachable, this advancement could help prevent the need to drill as many additional wells by using the tremendous volume Nakasawa has already found.
More efficient and sustainable TEOR technologies are very important to ensuring the continued health of the industry. Through advances like these, the increasing energy demands in the years to come can be met.
