Otto rejoined the ranks of producing oil companies in March 2018 when it commenced production from its 50% owned SM 71 oil field in the Gulf of Mexico shelf. As at 4 February 2019 Otto is in the process of completing and hooking up its latest discovery at Lightning in Matagorda County, Texas. Production is expected from Lightning by the end of March 2019.

Otto's strategy is to grow its Gulf of Mexico oil business through careful investment of its substantial cash flows from SM 71.
