Life isn't always easy for the integrated major oil companies, and this past quarter was evidence of that. With foreign oil prices slipping while U.S. prices climb, it's giving these big players problems. The benefit of being a major oil company, though, is having gobs of cash that can be used to buy out smaller players. ExxonMobil's (XOM 0.39%) deal for Celtic Exploration goes to show that for companies like ExxonMobil, gobbling up a $2.6 billion competitor is relatively easy money-wise.

Integrated majors buying smaller competitors is usually from a potent cocktail of struggling production, a bulging cash balance, and the right buying opportunity. So let's take a look at each of these factors and see who in the world of big oil is likely to make a big acquisition in the near future. 

Pitiful pumps
When a company like ExxonMobil needs to move the production needle, it needs to take on big projects. Not only do these projects take immense amounts of capital, but they also don't always turn out as planned. This past quarter, Royal Dutch Shell (RDS.A) announced that it was dropping its production growth targets because some of its projects were not turning out as hoped. Shell isn't alone, nearly all of the integrated majors have not been growing production as much as originally planned.

Royal Dutch Shell 3.314 3.262 (1.59%)

BP (BP 0.98%) 2.855 2.319 (18.77%)

What is compounding the problem even further, though, is that these major projects are in increasingly more difficult environments such as the arctic or in ultra-deepwater regions. These remote, high-risk regions also mean higher per-barrel costs. In 2012, the cost to replace a barrel of reserves for the integrated majors was considerably higher than for their smaller competitors.

BP $72.03

Of course, these numbers don't exist in a complete vacuum, either. Much of BP's struggles are more of a product of the Deepwater Horizon spill than operations. Over the past few years, BP has divested over $38 billion in assets to both refocus its operations and cover the costs of the spill. Also, both Chevron and Shell are in the process of bringing several LNG liquefaction terminals online. These high-cost facilities will inflate capital expenditure numbers, but will also result in big upswings in revenue once completed. Chevron estimates that the Gorgon and Wheatstone projects in Australia will add about 400,000 barrels of oil equivalent production net to the company.

Overall, though, it's becoming harder and harder every day for integrated majors to grow production, and buying out smaller competitors is becoming a more attractive option.

A fistful of dollars
One thing that stands out on the balance sheets of integrated majors is the huge cash reserves riding on those balance sheets. Of course, these companies do need to keep a sizable amount of cash on the books to pay the bills and whatnot, but Chevron's $22.3 billion in cash and short-term investments is more than the company needs for day-to-day operations and could go a long way toward buying up smaller producers.

What's on the menu?
One of the reasons that many of the major oil companies struggled last quarter is that they haven't quite gotten a strong foothold on the U.S. shale boom. So it would be logical to look for buys in the U.S. in order to balance out those pricing disparities. One potential opportunity that could be attractive is making a run at some of Occidental Petroleum's (NYSE: OXY) assets. The company seems destined to sell off some segments of its company in order to boost shareholder value, and any of the integrated majors could net a big win if any of these assets were to come up for sale. 

Another potential route is to team up with Chesapeake Energy (CHKA.Q) on some of its domestic assets as well. Chesapeake has more than $4 billion worth of joint ventures with Total, Sinopec, and CNOOC, and Chesapeake may be keen to sign another partnership to help foot the bill to develop some of Chesapeake's shale assets. This could also be attractive to the integrated majors because Chesapeake has prime acreage in almost every shale play in the U.S., which could provide a decent production bump on the cheap. 

What a Fool believes
Of the companies mentioned, it would appear that Chevron is in the best position to make a deal. However, bringing the Angola LNG facility recently and the big capital tied up in Gorgon and Wheatstone may give management pause before making any big moves. Also, BP's large cash hoard might stay on the books for a while until everything related to the Deepwater Horizon is cleared up, so making a big purchase is probably not a top priority right now.

Overall, though, there are several opportunities for a major oil company to swoop in and grab assets here in the U.S., so don't be surprised if we see a deal sometime soon.
