11/30/2010 -- Carrizo Oil & Gas, Inc. (NASDAQ: CRZO) today is providing an operational update on the Company's activities in the Eagle Ford Shale and Niobrara Formation. Carrizo's initial two Eagle Ford Shale wells were drilled from a common surface location in central La Salle County, Texas. The Mumme Ranch 10H was drilled with a 5,493 foot horizontal leg and was completed with 15 frac stages. The Mumme Ranch 12H was drilled with a 5,455 foot horizontal leg and was completed with 19 frac stages. Following the flow-back of completion fluids, the two wells were tested for production potential beginning on November 20, 2010. The Mumme 10H had a 24-hour initial production rate of 1,011 barrels of oil per day ("Bopd") while the Mumme 12H had a 24-hour initial production rate of 1,220 Bopd. Production from this two-well pad appears to have stabilized at the current combined rate of approximately 1,125 barrels of oil per day. Approximately 2 million cubic feet per day of 1,367 btu per mcf natural gas is currently being flared pending connection to a gas gathering pipeline. Carrizo has a 100% working interest and a 75% net revenue interest in these two wells.

Hydraulic fracture stimulation activities have been completed on the Company's next Eagle Ford well, the Pierce 10H, located to the southwest of the Mumme wells, and the well has commenced flow-back today. It is currently anticipated that initial production results for this well should be available before the end of the year. Carrizo owns approximately 20,000 net acres in the Eagle Ford Shale play, the majority of which are located in the condensate window of La Salle, Dimmit, and McMullen Counties. In addition to the three wells mentioned in this announcement, Carrizo has drilled two other Eagle Ford horizontal wells in La Salle County which are currently waiting on completion, expected to begin in the first quarter of 2011.
