For over 30 years, Nigeria has been the largest oil-producing nation on the African continent, but recent woes from some of the major players there might start to put that status at risk. Royal Dutch Shell (NYSE:RDS-A), far and away the nation's largest oil producer outside of the national oil company, anticipates that it will spend $12 billion to cover issues related to theft, sabotage, and embargoes that have caused the company to declare force majeure -- another way of saying that it can't meet its obligations -- on its LNG contracts in the region.

Tune into the video below where contributors Tyler Crowe and Aimee Duffy investigate who is losing patience in Nigeria and what companies will be in the market to buy these troubled assets.
