Any way you look at it, an investment in Royal Dutch Shell (RDS.A) over the past couple of years has been a disappointment. For the company to really turn it around, it will need to focus its attention on one key aspect of its project portfolio: liquefied natural gas. While Chevron (CVX 0.66%) and ExxonMobil (XOM -0.03%) may have big plans for LNG as well, Shell has a very long history in the game and its newest innovation, the Prelude floating LNG facility, could be a game changer for remote offshore natural gas projects. 

The focus on LNG could be a major win for Shell, but does it make the company a buy today? In this video, Fool contributor Tyler Crowe drills into Shell's development plans and how investors should view them.
