"Canadian energy giants Suncor Energy (NYSE: SU) and PetroCanada (NYSE: PCZ) announced their intention to merge; Suncor, a holding in our 'Wildcatters Portfolio' will be the surviving entity," says Elliott Gue.

In his The Energy Strategist, he explains, "The combined firm will be the fifth-largest energy company in North America and the largest in Canada." Here, he explains why the new stock remains a buy.

"The combined firm will have more financial flexibility than Suncor did on its own. Debt ratios will be healthier, and the combined firm will also be able to redirect certain planned capital expenditures to higher return potential projects.

TheStreet.com's Jim Cramer says the price of crude isn't high enough to reignite the oil drilling companies.

Crude's awesome and it's really pushing up the whole complex. The stocks of the oils and the oil drillers are powering higher even as drilling is going down hard. Is it possible that the integrateds are right and the drilling stocks are wrong? Or should they both be going up together?

I wrestle over this issue every day because one of the main reasons why oil is going up, besides the endless "dollar-going-down-oil-safe-haven" trade that the media loves to go out with in order to sound smart, is that the drilling around the world has been cut back dramatically. I think that a deal like Suncor (NYSE: SU) (Cramer's Take) and Petro-Canada (NYSE: PCZ) (Cramer's Take) is great for the oils. It makes me recognize that there is value here in the group. I also believe the demand is real.

Petro-Canada (NYSE: PCZ) will be purchased by Suncor Energy (NYSE: SU), the world's second-largest oil-sands producer, for about $14 billion.

PCZ will receive 1.28 shares in the new company for each of its shares, while SU holders will receive one share. PCZ April option implied volatility closed at 64, below its 26-week average of 71, according to Track Data, suggesting decreasing price movement.

SU April call option implied volatility closed at 82, puts at 89, above its 26-week average of 80, according to Track Data, suggesting larger price movement.
