2 ExxonMobil United States Production Organization ExxonMobil Artificial Lift ExxonMobil operates approximately 14,000 wells in the United States (onshore). Approximately 7,000 of those wells are gas wells. At some point in time all of these wells may become Artificial Lift candidates. Present Artificial methods in use to De- Water gas wells include: Velocity Strings, Foam injection, Plunger Lift, Gas Lift and Rod Pumps.

3 ExxonMobil United States Production Organization ExxonMobil USP Artificial Lift Automation Systems West Texas XSPOC & ABB Total Flow Electronic Flow Meters. South Texas Bristol Electronic Flow Meters & FBNet. Central and East Texas ABB Total Flow Electronic Flow Meters. Kansas and Colorado ABB Total Flow Electronic Flow Meters. Wyoming and North Dakota Fisher Electronic Flow Meters. 3

4 Challenges Facility configurations (Meter Sites 3 to 5 miles from well sites) Move the meter sites or use radios? Tubingless completions 3/8, 7/8 and 3 ½. 10,000 and 15,000 psi wellheads. Electronic Flow Meter s / Programmable Logic Controller s not standard throughout all field areas (Bristol, ABB Total Flow, Fisher, etc). Facility Logistics (remote sites, no electricity) Standardize automation systems regionally. I.E. XSPOC / ABB Total flow West Texas, FBnet / Bristol South Texas and ABB Totalflow North / East TX and Kansas 4

5 ABB / Total Flow SCADA WINCCU Plunger Lift Scada systems are built using the existing ABB Totalflow Electronic flow meter s. In the Perryton Texas Field ExxonMobil has approximately 170 plungers operating using ABB Total Flow s WINNCU as the central plunger lift SCADA System. 5

18 Ferguson Beauregard FBnet Scada (South Texas) Multiple wells flow to one meter site. Meter Site is 3 to 5 miles from the well. Well site has Ferguson Beauregard PLC with two radios, one to receive data from the electronic flow meter. One radio to communicate with host control in field office. Meter Site. Bristol electronic flow meter with two radios one to communicate with meter SCADA system and one to transmit well flow / pressure information from the EFM to the FB Plunger Lift Controller. 18
