Recent Gas Lift Developments
R-20H 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
