The focus of last week's preview was on oil and energy companies, and we saw that big oil had a good week, reporting better-than-expected results and record profits driven by high prices in the third quarter. Energy-related companies are well represented again this week and expectations in general remain high.

Early in the week, analysts surveyed by Thomson Financial anticipate that the big earnings gainers will include EOG Resources Inc. (NYSE: EOG), Anadarko Petroleum Corp. (NYSE: APC), and Cimarex Energy Co. (NYSE: XEC), which are expected to post profits of $2.24 per share (up 64.7% from a year ago), $1.48 per share (up 52.7%) and $2.26 per share (up 61.1%) respectively. All three of them have offered positive surprises in recent quarters, and analysts on average recommend buying EOG and Anadarko. Other expected big earnings gainers early in the week include Forest Oil Corp. (NYSE: FST), Pioneer Natural Resources Co. (NYSE: PXD), Comstock Resources Inc. (NYSE: CRK), and MasterCard Inc. (NYSE: MA). The earnings of phosphates producer Innophos Holdings Inc. (NASDAQ: IPHS) are expected to have risen 92.3% to $3.37 per share. Innophos beat estimates in the previous quarter by a whopping 210%, and analysts have been impressed with Innophos's lack of debt and pricing gains despite the slowing economy, so, on average, they recommend buying IPHS.

Also early in the week, analysts expect Goodyear Tire & Rubber Co. (NYSE: GT), Kaiser Aluminum Corp. (NASDAQ: KALU), and Oshkosh Corp. (NYSE: OSK) to report that their profits fell 52.9% to $0.33 per share, 45.1% to $0.67 per share, and 41.2% to $0.67 per share, respectively. These companies have tended to beat estimates in recent quarters, and the consensus recommendations of analysts are to buy them. However, PMI Group Inc. (NYSE: PMI), one of the largest private mortgage insurance providers in the U.S., is expected to take another hit as the housing slump drags on. The California-based company is expected to have widened its net loss from $1.04 per share a year ago to $2.43 per share in the most recent quarter. Its shares are down 84.5% from a year ago, and have been trading recently near their 52-week low.

Pioneer Natural Resources Co. (NYSE: PXD) is poised to be the first independent operator to produce oil on the North Slope, an area dominated by the major producers such as Exxon Mobil (NYSE: XOM) and ConocoPhillips (NYSE: COP), though other independents such as Andarko Petroleum (NYSE: APC) may not be far behind.

Ten-year-old Pioneer, based in Irvine, Texas, plans to begin drilling in a few weeks off the coast of Oooguruk Island, Alaska, in a field expected to yield as much as 90 million barrels of oil. Pioneer expects to begin producing oil from there in the first half of next year.

Pioneer's efforts are being closely watched to see whether independents can establish themselves on the North Slope. "Ours is a bellwether project," says Chief Operating Officer Tim Dove. "If we do well, make the project work in reasonable time and in a fiscally responsible manner, it could open up some avenues for us and other independents."

Pioneer also announced the start-up of its South Coast Gas (SCG) project, expected to produce approximately 50 million cubic feet of natural gas per day by the end of the year. Scott Sheffield, Pioneer's Chairman and CEO, says, "With the completion of SCG and considering that a majority of the capital costs related to our Oooguruk development on the North Slope will be invested by the end of 2007, we expect our 2008 drilling and development budget to decrease significantly as compared to 2007."

The share price has been rising since reaching a 52-week low of $35.51 in August after Pioneer's second quarter report. The share price at close on Friday was $46.02. Pioneer will report on its third quarter on November 6.
