15 Vessel at Service

16 Dynamic Positioning Positioning system to steer vessels in a controlled fashion Logic routine for maintaining station Redundancy GPS Optic Radar Maintenance and performance managed by Coast Guard 16

17 Operational Safety 1. Coordination 2. Pre-job 3. Operation 1. Vessel personnel will rig up flexible treating hose and flush/test 2. Pump stimulation treatment - 8 hr. 3. Rig down hose 17

18 Communications Stim Vessel Captain Drillship Captain Vessel Dynamic Positioning Rig Dynamic Positioning Stimulation Pumping Personnel Rig Completion Personnel 18

19 What if DP System Cannot Hold Station? Drillship and Vessel are continuously monitoring position and power required to maintain position At any sign of performance concern, job is halted; hose is placed back on vessel Emergency situations require immediate disconnect of the hose. The hose is released from the reel and hangs from engineered anchor to the rig. 19
