UnderCurrent™ Downhole Turbine Generator
What could you do better if you had unlimited downhole power?
Better depth of investigation? Higher definition? Stronger signals? New technologies? UnderCurrent™ Turbine Generator is a new wave in the downhole power market. UnderCurrent provides more power for less money than downhole Lithium Ion battery packs... PERIOD! Your downhole tools are no longer limited by the finite number of operational hours assigned to a battery pack. No more sacrifices in the quality or number of operations you need to perform downhole. When the mud pumps are on, UnderCurrent delivers!
Flexibility is the key to the UnderCurrent downhole generator system. The UnderCurrent downhole turbine generator platform itself is designed to deliver 200 watts of power at 200°C operation. You have the option of choosing our standard 48VDC regulated output that delivers 200 watts at 150°C, custom DC output to your specificied voltage, or 200° C 3-Phase output for you to mate with your own rectification & regulation electronics. If your bottom hole instrumentation requires power while the pumps are off, our engineers can accommodate by packaging it with a small stay-alive battery pack to provide seamless switching and continuous power.
