The Mumme Ranch 10H was drilled with a 5,493ft horizontal leg and was completed with 15 frac stages while the Mumme Ranch 12H was drilled with a 5,455ft 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 20 November 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 1,220bopd.
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 1,367btu 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.
In its Niobrara Formation acreage located in Weld County, Colorado, fracture stimulation activities are scheduled to commence on the State 16-11-9-60H in the first week of December.
The drilling of the vertical portion of the company’s second Niobrara well, the Bob White 36-44-8-62H, has been completed and protective casing has been installed through the curve.
