Exploring for new sources of oil and gas is an inherently risky and expensive venture. That's why Chevron (CVX 0.57%) really deserves to take a bow. As the following tweet details, the company is not only really good at what it does, but last year it was also the best in the industry at discovering new sources of oil and gas:

While a 74% exploration success rate might not sound like much, it was well above Chevron's own 10-year average of 54%. Think about that for a moment. Nearly every other exploration well Chevron has drilled over the past decade has come up dry. Yet that's a consistently solid success rate that many of its peers can only aspire to attain.

One area Chevron found a lot of success last year was in Western Australia, where it made six natural gas discoveries. Since 2009, Chevron has made a total of 20 discoveries in Western Australia, which are critical in supporting the three liquefied natural gas export facilities it has invested in with global partners such as Royal Dutch Shell (RDS.A) and ExxonMobil (XOM 0.39%). So far Chevron has added 10 trillion cubic feet of natural gas resources through these discoveries. For perspective, that's more natural gas than was used in electric power generation in the U.S. last year.

In the past 10 years, Chevron has added 10.2 billion barrels of oil equivalent resources thanks to exploration. What that has done is enabled the company to replace 73% of what it produced through exploration. That beat both Shell and Exxon, which replaced 67% and 33%, respectively. One of the big reasons is that Chevron hasn't been as active in acquiring companies to boost its reserves and instead has focused the capital it has invested to find new sources of oil and gas on its own.

One thing Chevron is not doing after last year's stellar year is resting on its laurels. Already this year it has announced a major discovery in the Gulf of Mexico with partners ConocoPhillips (COP 0.39%) and Anadarko Petroleum (APC). That discovery really demonstrates how good Chevron is at what it does. The company and its partners drilled a total of 31,866 feet, in water nearly a mile deep, to make this discovery. That's about 6 miles down, or 106 football fields laid end-to-end.

While that discovery is about half the size of the one that Conoco and Anadarko announced just a week before Chevron's, it is still massive. It's also just one of Chevron's success stories in discovering major oil and gas deposits in the Gulf over the past few years. Best of all, some of those projects are just starting to bear fruit. For example, its Big Foot field is expected to produce 75,000 barrels of oil and about 25 million cubic feet of natural gas per day at a total project cost of more than $4 billion. That one field equates to about 10% of the current oil production of the lauded Bakken shale. It's just one of the many projects Chevron is working to bring online even as it continues to discover new sources of oil.

Chevron does one thing really, really well, and that's discovering new sources of oil and gas to feed the world's voracious energy appetite. That success is giving the company increasing confidence that it can increase its daily production by 25% by 2017. What that means is that the money it spends on exploration really should start to pay off for investors over the next few years.
