1. Objectives for Basic Gas Lift Seminar

2. Gas lift Workshop HISTORY -WALS HAS CONDUCTED SEMINARS FOR MANY YEARS
-BASIC FORMAT BY TOM RYAN (MACCO)
-EXPANDED AND IMPROVED UPON
-ORIGINALLY A ONE WEEK SEMINAR
-REDUCED TO THREE DAYS AT CUSTOMERS
REQUEST

3. Gas Lift Workshop SEMINAR TYPES TECHNICAL SESSION THAT INCLUDES THEORY
EVALUATION
GRAPHICAL DESIGN
TROUBLESHOOTING
VALVE MECHANICS
PRACTICAL SESSIONS
ADVANCED GAS LIFT COURSES

4. Gas Lift Workshop CURRENTLY -SCHEDULE FOUR DOMESTIC PER YEAR
-IN-HOUSE TRAINING ON REQUEST
-INTERNATIONALLY BY REQUEST
-TWO INSTRUCTORS AT ALL TIMES
-OVER 100 PARTICIPANTS PER YEAR

5. Gas Lift Workshop PURPOSE TO FAMILIARIZE CURRENT AND POTENTIAL
CUSTOMER WITH THE APPLICATION OF GAS LIFT
TO IMPROVE THE KNOWLEDGE AND PROFICIENCY OF
GAS LIFT COMPANY PERSONNEL

6. Gas Lift Workshop SCOPE THE SEMINARS ARE DESIGNED TO FAMILIARIZE THE
PARTICIPANT WITH GAS LIFT APPLICATION AND
OPERATING PRINCIPLES WHILE EMPHASIZING THE
EFFECTS BETWEEN THE GAS LIFT AND THE
PRODUCING SYSTEM

7. Gas Lift Workshop COURSE ORGANIZATION
ULTIMATE GOAL SET FOR PARTICIPANTS IS
TO LIFT AS DEEP AS POSSIBLE WITHIN THE
CONSTRAINTS OF THE SYSTEM
USING OTHER OBJECTIVES AND CLASS
PROBLEMS,WE WORK TOWARD THAT GOAL

8. PowerPoint Gas Lift Workshop VISUAL AIDS USED DURING SEMINAR
WELL MODEL
EQUIPMENT CUTAWAYS
ANIMATIONS
SOFTWARE
WEM, VALCAL, VPC

9. Gas Lift Workshop OBJECTIVES
FIRST, WE DEFINE THE DIFFERENT APPLICATIONS OF GAS LIFT AS USED IN
CONTINUOUS FLOW
INTERMITTENT FLOW

10. Gas Lift Workshop OBJECTIVES DEFINE AND DISCUSS THE AREAS OF THE
PRODUCTION SYSTEM THAT REQUIRE PROFILING
DISCUSS THE TOOLS AVAILABLE TO
ACCOMPLISH THE TASK AND THEIR LIMITATIONS

12. Gas Lift Workshop
THREE AREAS TO DEFINE
RESERVOIR
VERTICAL
HORIZONTAL

13. PRODUCTIVITY INDEX

14. INFLOW PERFORMANCE RELATIONSHIP VOGEL
SBHP
F.E. = 1.0

15. MULTIPHASE FLOWING GRADIENTS

16. Multiphase Flowing Gradients

17. VERTICAL PERFORMANCE VERTICAL FLOW CORRELATIONS :
SHOULD BE SELECTED BASED ON COMPARISON WITH ACTUAL MEASURED DATA.
WHEN NOT AVAILABLE, SELECT DATA FROM A WELL PRODUCING UNDER SIMILAR CONDITIONS.

18. Gas Lift Workshop OBJECTIVES APPLY PROCEDURES USED FOR EVALUATING
POTENTIAL OIL WELLS FOR THE
APPLICATION OF GAS LIFT
USE “HANDS ON” GRAPHICAL DESIGN AND
VERIFY WITH SOFTWARE

19. WELLHEAD PRESSURE VS. PRODUCTION

20. EFFECT OF OPERATING DIFFERENTIAL

21. WELL EVALUATION

22. WELL EVALUATION

23. WELL EVALUATION

24. Gas Lift Workshop OBJECTIVES DEMONSTRATE CONTINUOUS GAS LIFT DESIGN
METHODS FOR IPO AND PPO VALVES
DESIGNS ARE ACCOMPLISHED WITH “HANDS
ON” METHOD AND VERIFIED WITH SOFTWARE
CURRENT AND FUTURE CONDITIONS
CONSIDERED AS WELL AS MINIMUM DATA

25. Gas Lift Valve Spacing

26. CONTINUOUS FLOW GAS LIFT DESIGN

27. Current and Future Conditions

28. Gas Lift Workshop OBJECTIVE EXAMINE THE MECHANICS OF IPO AND PPO
G.L.V.’S AND THEIR GAS PASSAGE
CAPABILITIES AS PER VPC

29. PRESSURE VALVE FORCE BALANCE EQUATION
PO (AB-AP) + PT (AP) = PVC (AB)
POAB -POAP + PT (AP) = PVC (AB)
POAB - POAP + PTAP = PVC AB
AB AB AB AB
PO - PO AP + PT AP = PVC
AB AB
PO ( 1 - R) + PTR = PVC
PO = PVC - PTR
1 - R

30. Gas Lift Workshop

31. Typical Loadrate Test Data

32. Gas Lift Workshop OBJECTIVE PRESENT AND DISCUSS SOME OF THE
AVAILABLE TOOLS FOR EVALUATING OR
TROUBLE SHOOTING GAS LIFT INSTALLATIONS
DISCUSS ADVANTAGES AND LIMITATIONS
DISCUSS CORRECT METHODS OF USE

35. Gas Lift Workshop OBJECTIVE DISCUSS CURRENT METHODS AND PROCEDURES
BEING USED FOR OPTIMIZING GAS LIFT
OPERATIONS

37. BENEFITS Gas Lift Workshop PARTICIPANTS REALIZATION OF THE VALUE OF
QUALITY DATA FOR OPTIMIZING THE APPLICATION
BEFORE AND AFTER INSTALLATION
REALIZATION THAT THE EFFICIENCY OF THE SYSTEM IS
IMPROVED AND TROUBLESHOOING MINIMIZED WITH
THE PROPER APPLICATION OF THE GAS LIFT EQUIPMENT

38. BENEFITS Gas Lift Workshop PARTICIPANTS FROM MANY DIFFERENT AREAS
EXCHANGE IDEAS FOR REMEDIES TO PRODUCTION
PROBLEMS
MOST IMPORTANT, WE BECOME MORE AWARE OF THE
PROBLEMS AND NEEDS OF OUR CUSTOMERS AND OUR
INDUSTRY
