While other earnings may have disappointed last week, the news was good for oil giant ConocoPhilips (NYSE: COP). In what some took as a good sign for big oil, the Houston-based company reported that third quarter net income surged 41% year over year to $3.39 per share, and that revenue also surged 52% to $70 billion. We'll see whether the good news extends to other petroleum giants scheduled to report quarterly results this week.

Analysts surveyed by Thomson Financial are looking for BP (NYSE: BP) profits to have grown 43.2% in the most recent quarter to $2.34 per share on revenue of $109.7 billion, and Chevron Corp. (NYSE: CVX) to post earnings up 39.4% to $3.25 per share on revenue of $86.8 billion. Marathon Oil Corp. (NYSE: MRO), ExxonMobil Corp. (NYSE: XOM), and Royal Dutch Shell (NYSE: RDS.A) likewise are expected to report higher net income of $2.33 per share (sales of $23.4 billion), $2.40 per share (sales of $131.4 billion), and $2.65 per share, respectively. Even Valero Energy Corp. (NYSE: VLO) is expected to post earnings slightly higher to $1.46 per share (sales of $36.4 billion), despite the effects of Hurricane Ike. Among these companies, only BP and Valero beat earnings expectations in the previous quarter. Not surprisingly, analysts on average recommend buying all except Valero, and shares of all of these companies have recently hit 52-week lows.

One of the top stories on Bloomberg today discusses a problem I have highlighted multiple times in the Ville over the past year: the accelerating decline of Mexico's Cantarell oil field. The latest numbers show Cantarell oil production falling to a 12-year low. I expect the decline in production from Cantarell to only accelerate.

If I am correct, crude oil supply for the United States is going to get tighter in the coming months. Today, we found out Pemex was having problems meeting commitments to Texas refineries due to falling production. I expect this problem to get more press in the future as Cantarell production accelerates to the downside and US refiners are forced to look to an already tight oil market for additional supply.

The Commitment of Traders report comes out today due to the holiday last week. The last COT report for crude oil showed commercials net buyers (first time since February 2007) and one has to wonder why...perhaps commercial traders see the coming collapse in Mexico oil production? I have repeatedly said the COT reports are still bullish for crude and am looking forward to seeing this weeks report when it is released later today.

My favorite energy names continue to be BPZ Energy (AMEX:BZP) and Pacific Rubiales (PEG:CA), both of whom have catalysts in the next month that could move the stocks.

On a housekeeping note, the Hindenburg signal and head and shoulders patterns I highlighted in the S&P and Russell 2000 seem to be playing out. My minimum target on the S&P500 is/was about 1225, which also happens to be in the neighborhood of the 2006 lows.
