23 Oil Industry Stocks to Consider for Your Stock Portfolio

NEW YORK (TheStreet) -- With so many different investments options, investors often have a difficult time deciding which direction is the best one for them to take.

Here at TheStreet, we attempt to declutter the excess of information available and present it to our readers in a way so they can make wise investment decisions.

Whether you're an individual investor or work with a financial adviser, our objective is to help simplify the process and present information that's user friendly.

Quite simply, the oil and gas industry is the largest by revenue in the world. The industry as a whole amassed nearly $1.25 trillion in revenue in 2012, according to Ernst & Young's 2013 "Global Oil and Gas Reserves Study." Oil and gas companies comprise seven of the top eight largest companies by revenue worldwide. In fact, ExxonMobil's total revenue of $482 billion is larger than the 2012 GDP of all but 25 countries.

Not only is it the largest by revenue, but also it is one of the most profitable industries in the world. Oil and gas extraction have a net profit margin of 16.4%, according to Sageworks. It comes third only to accounting, tax preparation, bookkeeping and payroll services at 17.8%, and legal services at 19.8%.

Despite its long-running success, the oil industry has proved to be extremely volatile. For example, in the past 10 years, the price of WTI Crude Oil has plummeted as low as $43/bbl and peaked as high as $140/bbl. Similarly, the price of natural gas has dropped as low as just above $2/MMBtu and has reached as high as nearly $14/MMBtu during that same ten year time period.

The oil industry is massive; made up of many different segments such as integrated energy, contract drilling, services and equipment, and exploration and production. Because of its size, complexities and power, tackling the industry can be quite challenging for the average investor.

What follows are 23 oil industry stocks, ranked by our own proprietary quantitative ranking system at TheStreetRatings.com, which are worth looking over. Note that these ratings can change at any time. If you would like access to real-time ratings of these stocks, you can subscribe to TheStreet Quant Ratings.

The company's strengths can be seen in multiple areas, such as its impressive record of earnings per share growth, compelling growth in net income, revenue growth, largely solid financial position with reasonable debt levels by most measures and notable return on equity. We feel these strengths outweigh the fact that the company shows weak operating cash flow."
