Welcome to our Natural Gas series aimed at introducing investors to the fundamentals of the industry. We've already covered the production basics, and horizontal drilling and hydraulic fracturing, so today we dive into numbers -- introducing the metrics that can be important in evaluating individual companies and the industry at large.
Instead, investors should flip to the "Proved Reserves" table in the company's 10-K. We'll use Anadarko (NYSE: APC ) for these exercises, its table is below:

Now that we have our data, let's learn how to get it to say what we want to hear.
Reserve life index
Anadarko's reserve life index is 11 years. Intuitively, it is easy to assume that the higher the RLI the better. In reality though, a high RLI, say 25 years, could mean that a particular company is unable to develop its reserves which could illuminate a more serious problem (no money!).
It's also important to note, after a merger or acquisition it is possible for this number to be high simply because the parent company has not yet had the opportunity to develop those reserves.
Reserve replacement ratio
Anadarko's reserve replacement ratio is 150%, which means the company does in fact replace reserves from year to year.
Gas companies can replace reserves in two ways. "Through the drill bit" refers to reserves replaced through exploration. "Bought" refers to increased reserves through acquisition. Through the drill bit is the preferred method because it implies firsthand knowledge of the new gas and reinforces a company's claim to technical prowess.
While these ratios seem pretty straightforward, this wouldn't be the natural gas industry – heck, this wouldn't be investing – without some sort of discrepancy in the way companies account for and report reserves.
Reserves are the major assets of any oil and gas company, but they only get paid for what they pull out of the ground and it's important to keep that in mind at all times.

The domestic price of natural gas is now so low that companies are almost guaranteed to lose money if they don't operate efficiently. Here are the most recent break even points for 10 natural-gas-producing companies:
