From early June 2007 to mid-June 2007, we began drilling the William 4-10 well, which reached a depth of 4,810 feet. The well was found to contain four potential commercial pay zones, including Wilcox Sand, Mississippi Lime, Layton Sand, and Tonkawa Sand. The Wilcox Sand zone was completed in mid-August 2007. Production from the well began in mid-October 2007.
