Carrizo Oil & Gas raised oil production growth guidance from 28% to 40% earlier in the summer due to improving well results in the Eagle Ford.

The company also raised second quarter oil production guidance from ~9.800 boe/d to ~11,000 boe/d. That represents and increase of more than 12%. There were a few factors that led to the increase:

Oil production is outperforming expectations, while gas and NGL production is coming in at the high end of guidance. Carrizo increased its company-wide growth target from 6% to 10% for the year.

Carrizo is running three rigs in the Eagle Ford, one in the Niobrara Shale, and one in the Marcellus Shale. Along with production guidance, Carrizo increased its capital spending plans by ~$35 million to $530-540 million in 2013.

In the Eagle Ford Shale, Carrizo is increasing planned 2013 drilling activity by three wells as a result of increases in drilling efficiencies, and increasing planned completion activity by 35 net frac stages primarily for lease management purposes.
