That's right. As far as we know, the "black site facility in the Baltic Sea" is where Jensen got his augs, and Vadim Orlov (the dead scientist) is the one who installed them.

This facility is not named and the details behind it are a mystery, but it is mentioned in various in-game emails as "BH." "BH" probably stands for "Baltic Headquarters" (but "Black Helix" and "Blue Helix" are other possible candidates).
