1 New Gas Lift Products & Technology Roger Stinson Product Manager - Gas Lift Schlumberger Artificial Lift Systems Spring 2002 Gas Lift Worksop February 5, 2002

2 Recent Gas Lift Developments R-20H 3000 psi IPO Gas Lift Valve WRFC-H(hydraulic) & WRFC-E (electric) Surface Controlled Flow Control Automated Surface Gas Injection Equipment RIPC Normally Open Gas Lift Valve Begin Development of High Performance Gas Lift Valve (Q ) Begin Development of Single Integrated Software Package for Artificial Lift Analysis and Design based on recent Baker Jardine acquisition (Q1-2002)

3 R-20H 3000 psi IPO Gas Lift Valve Based on current gas lift valve technology & geometry Conducted load rate tests, flow tests, & bellows cycling tests –High load rate as compared to R-20 –Proper gas lift design considerations required to assure well will unload –Improved bellows life cycle at high valve set pressures Currently in field test/evaluation Interim Solution

4 Surface Controlled Subsurface Gas Lift Valves WRFC-H -Hydraulically Controlled –Variable orifice ( 6 incremental control positions) –Considerably more costly than tradiional gas lift equipment –Primary application as a reservoir management tool –Slickline retrievable valve section WRFC-E - Electrically Controlled –Variable orifice (infinite over entire range) –Pressure monitoring –Reservoir Management tool –Slickline retrievable valve section

5 Recent Gas Lift Developments Automated Surface Gas Injection Control –Utilizes Camco/Merla FCV –Jordon Electronic Actuators –Remote monitoring and control capabilities RIPC Normally Open Gas Lift Valve –Limited applications –Closes with increase in gas injection pressure –Undergoing modifications

6 Future Development- High Performance Gas Lift Valve 5000 psi Subsurface Controlled Gas Lift Valve Required to allow for operational flexibility True Research and Development Project –Not constrained to current bellows technology –Not constrained to current geometry requirements Reliability and durability will be primary design objectives Development funded in R & E budget Two year project Possible basis for next generation gas lift equipment

7 Future Development- Integrated Artificial Lift Software Single package for AL design, and analysis (PipeSim (Baker Jardine)) –Tool for evaluation and selection among artificial lift options –Seamless use of input data from evaluation and analysis to design to troubleshooting to optimization Gas Lift Nodal Analysis Enhancements –Evaluate based on deepest point of injection with available injection pressure –Evaluate based on mandrels in place Gas Lift Design Enhancements –Improve IPO and PPO gas lift design capabilities –Interactive design process to allow user adjustments

8 Questions & Discussion
