Operator Byron Energy has completed drilling to the intermediate casing point at 7,837 ft (2,389 m) measured depth or 7,684 ft (2,343 m) true vertical depth of the SM6 #2 well, located at the South Marsh Island block 6 in the Gulf of Mexico.  

Partner Otto Energy said that in the drilling of the F sand intervals, a number of discrete hydrocarbon-bearing sands have been intersected consistent with or better than those seen in offset wells.

In F20 sand, a net hydrocarbon-saturated sand thickness of 10 ft (3 m) measured depth (MD) was observed. In F30 sand, a net hydrocarbon-saturated sand thickness of 32 ft (10 m) MD was shown. Finally, in F40 sand, a net hydrocarbon-saturated sand thickness of 60 ft (18 m) MD was detected.

These results will be incorporated into updated reserve information following the drilling operations. They may add to the existing reserve assessment of the F sand intervals in the SM-6 #1 BP02 well completed in July 2014.  

Current operations at the SM-6 #2 well are preparing to run the 9 5/8-in. casing before drilling ahead into the primary G20 target sand interval.  

The well remains on target to be completed with the pre-drill estimated timing of 40 days.
