Hercules 204 Ready to Spin Bit at Main Pass

The Hercules 204 jackup arrived on location to drill the Main Pass Block 20 No. 4 exploration well in the Gulf of Mexico. Drilling should start in the next few days. The well is targeting natural gas and associated oil potential in Upper Miocene Bigenerina Humblei sandstone reservoirs, which are in a structurally superior position to zones previously proven productive in the Main Pass 20 No. 1 well drilled by Devon Energy Corporation in 2001. The objective section is characterized by a lens-shaped, high amplitude seismic anomaly of up to 492 feet (150 meters) in thickness that was identified by Petsec Energy from its reprocessed 3D seismic database. LLOG Exploration Offshore, Inc. serves as the operator of the well, holding a 46.5% interest.
