HOUSTON, Nov. 30
-- Carrizo Oil & Gas Inc., Houston, said its first two Eagle Ford shale wells drilled from a common surface location in central La Salle County, Tex., appear to have stabilized at a combined 1,125 b/d of oil and 2 MMcfd of 1,367-btu/Mcf of gas.

Mumme Ranch 10H has 15 frac stages in a 5,493-ft lateral, and Mumme Ranch 12H has 19 fracs in a 5,455-ft leg. Initial production rates were 1,011 b/d at Mumme 10H and 1,220 b/d at Mumme 12H. Carrizo is flaring the gas pending connection to a gathering system.

Carrizo has a 100% working interest and a 75% net revenue interest in the two wells. The next well, Pierce 10H southwest of the Mumme wells, has begun flowback after frac.

Carrizo owns 20,000 net acres in the Eagle Ford play, the majority in the condensate window of La Salle, Dimmit, and McMullen counties. The company has drilled two other Eagle Ford horizontal wells in La Salle County that are awaiting completion, expected in the first quarter of 2011.

In Weld County, Colo., where Carrizo owns 59,000 net acres in the Niobrara play, crews are preparing to frac the State 16-11-9-60H well on Dec. 1. The horizontal leg is being drilled at Bob White 36-44-8-62H, and next the rig will move to drill a third well in 36-9n-61w.
