The Barton Hall Cecil #1H and #2H each ested at 4.2 MMCFED. Sales line connections are expected into an Energy Transfer pipeline in late July assuming no further rain delays. Four additional horizontal wells nearby in SE Tarrant Co. have been drilled and should be fracture stimulated in late July. Two additional SE Tarrant wells are currently being drilled. Carrizo has a 100% working interest in all of its SE Tarrant wells.

The current drilling plan will utilize two drilling rigs dedicated to SE Tarrant for at least eighteen months with each rig drilling an estimated one horizontal well each month. Carrizo's third rig is splitting its time drilling horizontal wells in Tarrant, Parker and Hood Counties. The Company's fourth drilling rig is drilling horizontal wells in Parker and Hood Counties.

The frac and flow test program on the Miller A-14 well (in the "Mega-Mata Prospect") located in Matagorda Co., Tx. is essentially complete. Carrizo attempted a total of four fracture stimulations in the wellbore testing several zones. The first three intervals tested at rates between 0 and 800 MCFD with the final attempt (currently completed interval) testing at rates up to 3,200 MCFD and sustained a flow rate of only 1,500 MCFD with 8,300 psi over an extended test period.

The gas stream contains 9% CO2 and 30 ppm H2S on average which would require gas treatment acilities to produce. Profitability of further development and reserve potential are impacted by the nature of the gas stream and the low reservoir permeability and will be evaluated after an additional extended flow period. Carrizo has a 28% working interest and Petrobras has a 72% working interest.
