In one of the most satisfying series of articles I've penned for the Fool, I recently stepped through the process that I personally employ when investigating an unfamiliar stock for the very first time. Sure, it happened to be an oil and gas producer, but I think any reader interested in sleuthing a stock, whether it's a value name like Lowe's (NYSE: LOW) or a hot new IPOlike A123 Systems (Nasdaq: AONE), should find the articles of interest. In case you missed it, here's a breakdown of the series.

In Part 1, we met Gulfport Energy (Nasdaq: GPOR), a small-cap exploration and production (E&P) company. Straight off the bat, we eyeballed the firm's share structure and capitalization. You wouldn't assemble a fantasy baseball team without studying players' stats, right? So it goes with stock picking. This quick review highlighted a debt load that required immediate attention, and a reading of the most recent SEC filings revealed a somewhat strained liquidity situation. We concluded that, like ATP Oil & Gas (Nasdaq: ATPG) and Hercules Offshore (Nasdaq: HERO) this week, Gulfport will likely issue stock to pay down debt.

In Part 2, we sized up the players involved, from the Board and management to key shareholders. This pointed us to a tangled web of relationships centered on Wexford Capital, which is also involved with Bronco Drilling (Nasdaq: BRNC) and the recently restructured Energy Partners Ltd , where a former Gulfport CEO now runs the show. Gulfport's proxy made for interesting reading, with all sorts of related party transactions detailed.

From there we proceeded to Part 3and Part 4, in which we assessed Gulfport's production and reserves. Some unfavorable findings here nearly led me to throw in the towel, but a few Fools urged me to continue. I'm glad they did, because that gave us a chance to cover another rather distinct aspect of the business -- Gulfport's stake in the Canadian oil sands. You can read all about that in Part 5.

We concluded with a preliminary valuation in Part 6, primarily using market transaction multiples to value each piece of the corporate pie. This approach increases our reliance on prevailing sentiment, but avoids forecasting folly. I won't spoil the ending, but I should mention that if we were correct in Part 1 to assume that a share dilution is coming, my estimate of Gulfport's per-share value would currently be too high.

So newbies, are you still feeling in the dark when it comes to oil and gas investing? Or, for those more advanced investors, do you think I flubbed something in my analysis, or overlooked an important topic? Let's talk it out in the comments section below. And if you have questions about where I dug up any of the information cited throughout the series, or have other oil and gas companies you would like to see covered, let me know!
