In early June 2007, we started drilling the William 4-10 well and it drilled to a depth of 4,810 feet in mid-June 2007. The well's electric and radiation logs indicated that it contained four potential commercial pay zones: the 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.
