Samson Oil & Gas provides operational advisory The Bluff #1-11 well has set a drillable bridge plug at 7,160 feet in the intermediate casing and the pressure was bled off enabling drill pipe to be run into the hole to the top of the plug. Currently the rig is conditioning mud in preparation to drill out the plug and to prepare the open hole for logs. During the well control operations last evening a gas sample was obtained, and has been analyzed and has determined a 97% nitrogen content with 2% methane and heavier hydrocarbons. The generation of nitrogen is thought to be associated with dolomitic zones that are encased in anhydrite. The proposed drill pipe conveyed logging program will enable the various oil shows that were recorded in the Permian, Pennsylvanian and Mississippian targets to be evaluated. Oily mud was observed at 8,090 feet and 8,430 feet and the mud analysis recorded up to 5% of contained oil at 8,650 feet.
