Why do the research when someone else can do it better for you?
Berkshire Hathaway has been buying large quantities of $OXY for almost a year at a price of around $60. Despite these purchases, the stock price hasn't moved anywhere and is at similar levels.
Such purchases indicate to me that Berkshire has confidence in Occidental Petroleum, so why shouldn't I?
Warren Buffett himself described these purchases as a long-term bet on rising oil prices.

Berkshire Hathaway owns about 25% of $OXY at this point.
I have almost no knowledge of the industry myself, but it seems to me that I wouldn't step in a puddle here.
How do you feel about $OXY?
