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 2 April 2019 Otto is in the process of hooking up its latest discovery at Lightning in Matagorda County, Texas. Production is expected from Lightning within the current quarter.

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