Thanks, excellent discussion. So to minimize oscillation a packer assembly with short tailpipe would beneficial. I have been playing around with that idea myself. Yes the Turner rate (droplet models) are significantly under estimating critical rate especially in larger deviated wells, I though this was due to the regime change (accumulation) being dominated by liquid film reversal. Do you have any SPE papers on the work presented in this video? Thanks in advance.

Thanks for the comment and feedback, and sorry for such a slow response but I don't have any SPE papers on this I have presented this at a few ALRDC gatherings etc. I also enjoy Dr. Nagoo's view and papers on this subject (you can find him on linkedin as well) he has a very interesting model developed.

Great video. This is very timely for me. I just moved to a field with poor boy, gas lift and GAPL wells that I want to understand and optimize.

Question I have is should we start running standing valves in a Hz well earlier then a conventional well?
@plungerliftcanada2 жыл бұрын
The application of standing valve in HZ is a great question The way I look at it is 3 fold If the well is new and the well will hold a fluid level above the BHS and is +100 bbls per day I typical don’t instal a standing valve Then there’s 2 choices in standing valve #1 relief type SV which has some early application in HZ, but… if your landed let’s say at 45 deg and End of tubing is 70 with a TV depth between of 250 ft when the well shuts in and fluid starts to collapse under the SV bhs and on top of the bhs - a relieving Standing valve will basically open up and let the fluid drop until it equalizes Most Relieving bhs only hold about 20-40 psi DP before they open If you have a column of fluid 250 ft tall collapsing under the bhs it can quite possible over balance (low pressure from collapsing fluid under SV & fluid column weight on top) 30 psi is only about 70 ft of water column I find non releasing Standing valves perform better later in life and if you have a long tail joint length under the BHS because of what I described above can’t happen in a non releasing SV The down side is it’s also possible to load a well up where you might require swabbing If you are using GAPL (gas assisted plunger lift) I would recommend to run a non relieving standing valve BUT that only once our fluid rates are under 100 bbls per day otherwise 100 bbls per day + I start with no standing valve and evaluate is my “rule of thumb” But this rule of thumb fluid rate can/will change some based on maximum injection pressure available, total depth of well etc.

Great conversation! New ops engineer here focusing on optimization and I’ve watched this video about 5 times over the last 2 weeks. Thanks for continuing to put out plunger related videos!

Glad you enjoyed it! we are working on a second podcast in the next few weeks focused on plunger lift issues and then possibly a few gas lift conversations as well. thanks for taking the time to comment!

Hi.I worked with a plunger elevator, the technology is good but requires a specific approach. For highly paraffinized oil and a long time between cycles leads to additional costs. This technology requires an individual approach and individual selection of candidate wells, with a low water content, a large gas factor and a low paraffin content in oil.But I have a question in which program the animated drawing of the plunger lift in the video is drawn.

I love the comment about only changing one setpoint at a time. Patience is a virtue with plunger wells and I even find myself from time to time rushing changes or making multiple changes. Also could not agree more documentation is key.

Question I have on Ball and sleeve plungers is how do you track arrivals consistently. I have ran them in the past and a few recently and have yet to find a plunger sensor that will detect arrivals consistently.
@plungerliftcanada2 жыл бұрын
There is a couple of things I have always done (especially if your using Titanium plungers) First is set the sensor up at the strike disk so the sensor can see it move Titanium is non magnetic so a sensor won’t see It come in but they will see the impact or strike disk move I also always “accept” the plunger gets missed once and awhile with pacemakers so I set the total open or wait time to equal the plunger rise + delay time I find 99% of the time the plungers make it but are just missed because the ball drops out or just come in so soft so I ignore 1 missed arrive but if it misses 2 or three times then is shuts in for the extended period to built up some pressure I typically make the extended closed period - to the minimum required closed I would need to get a conventional plunger to the bh spring

Another thing you will notice with ball and sleeve plungers before dimples is the ball will start getting egg shaped which reduces the ability to seal. It could also cause it to become stuck in the sleeve preventing it from cycling correctly.

Your video is really nice but it's hard to keep up with you as you speed paint. Some verbal techniques & sizes of your brushes you use would help. TYSVM for taking the time to share your video.
