Carrrizo Makes Discovery with Shady Side #1 Well

Carrizo Oil & Gas has drilled the Shady Side #1 well in St. Mary Parish, Louisiana to a total depth of 18,000 feet. The well logs indicate 77 feet of apparent net pay in the MA sands along with another 58 feet of partially depleted pay uphole. The shallower DB-3 sand was non-commercial. Operations are currently underway to complete the well in the MA sands. Carrizo is the operator of the well and owns an approximate 35 percent working interest.

"The Shady Side #1 is one of the largest discoveries Carrizo has made," commented S.P. Johnson IV, Carrizo's President and Chief Executive Officer. "We are currently evaluating a follow-up well. This success validates our strategy of adding a measured component of higher risk/higher upside to our exploration program."
