It was suspected that this batching was unsuccessful due to theinability to get the foamer through the high level of liquid in thewell, therefore MOCL did not proceed to inject foamer into any
Production Control Services(PCS) Data Sheets filled out and sent to PCS
Plunger lift evaluation completed by PCS using:Fekete Virtuwell Software, and Foss & GaulEquations
Once calculations completed PCS produced aconventional plunger recommendation for eachwell stating : whether a plunger lift candidate ornot, size of plunger to be used, and cycle times
Premier Integrated Technologies Pacemaker technology is thebest solution for removing liquid loading due to the Tupper fieldspast experiences with this technology installed on wells that areno longer able to flow on intermitters
Capillary Strings are very expensive compared to plunger lift,therefore making this application not as economical as plunger
lift technology. Further weighted foamer analysis needs to takeplace before this AFL application is considered, which will allow abetter understanding towards achievable production rates whenusing capillary strings
Production Control Services does not sell Pacemaker PlungerLift Technology, which allows a well to flow 24 hours a daytherefore allowing less pipeline, and gas processing problems.
Also PIT’s conventional plungers are more economical for Murphy Oil Company than the PCS’s conventional plunger applications
Weighted foamer is currently not a solution for unloading liquidloaded gas wells in the Tupper Field
Recommendations After analysis has been completed it is concurred thatthere is no single artificial lift option that can solve every
liquid loaded well problem in the Tupper field. It isrecommended that liquid loaded wells that flow less than10 E3m³/d, should immediately have an intermitter timerenabled to increase daily gas production. Once a well is
experiencing serious liquid loading to the point that anintermitter is not effective at keeping it flowing; PITPacemaker plunger technology should be installed if thewell meets all criteria. If the well doesn’t meet Pacemaker plunger lift criteria I recommend installing a PITconventional plunger application. Plunger lift will help with
future salt precipitation in the majority of the tubing, yet it isnot a completely effective solution. I don’t recommendusing the BJ RCI 08025W weighted foamer again in theTupper field, because in the past it has not removed anyliquid loading due to high liquid columns in the wellbore.
