It means that my well is a fizzler instead of a sizzler. But would be worse if it were on a 24/64 choke.
9875 MCFD; 16/64 CHOKE;
Thanks for the info, Jay.
sigh...

LP, no - it means your well could flow at a much higher rate on a larger choke size. If the following is your well the flow rate might be as high as 15-20 MMcfd on a 24/64" choke size as the flowing pressure was fairly strong. Chesapeake has choked this well back as evidenced by the one-quarter inch diameter choke size.

Chesapeake, Kelley 19 #H1 Well, Serial #239582, S19-T15N-R14W, DeSoto Parish, 9875 Mcfd, 16/64" Choke, 7225 psi Flowing Pressure

That looks much better. Yes, that's my well. So...it has the potential for a higher flow rate?
Ok...Makes me feel better.
Thanks so much, Les !

Congrats LP

It's much better than my well 2 sections over, its been shut in for almost a year. LOL

Many of the wells that have IP's over 20 million cu ft/day have flowing pressures above 8,000 lbs. on 16/64 chokes. They also have flowing pressures above 8,000 lbs. with 20/64 and above chokes.

SB, I hate to disagree but I have not seen any well over 20 MMcfd flowing over 8000 psi or with a 16/64" choke. Generally wells that had flowing pressures over 8000 psi tested at rates closer to 10 MMcfd.

Some of the strongest wells are as follows:

Petrohawk, Brown 17 #4 Well, Serial #238222, S17-T16N-R11W, Bossier Parish, 24155 Mcfd, 26/64" Choke, 7700 psi Flowing Pressure
Questar, Rex Young 6 #H1 Well, Serial #239383, S6-T14N-R11W, Red River Parish, 25507 Mcfd, 28/64" Choke, 7700 psi Flowing Pressure
Petrohawk, Sample 8 #H1 Well, Serial #239051, S8-T14N-R11W, Red River Parish, 22071 Mcfd, 24/64" Choke, 7951 psi Flowing Pressure
EnCana, Conway Harris 22 #H1 Well, Serial #239250, S22-T14N-R11W, Red River Parish, 18427 Mcfd, 21/64" Choke, 8335 psi Flowing Pressure

Les,

Wouldn't the 16/64 choke increase the pressure?

Parker, the smaller choke would increase the flowing pressure but would reduce the rate by ~ 55% to 65%.

When Petrohawk announces it publicly, I'll show you the numbers on a well in 15/11, Les. I did not mean to infer that any well was flowing over 20 million cu ft/day on a 16/64 choke, but rather that I'm aware that the same well that may be making say 15 million on a 16/64 with over 8000 lbs. flowing pressure the next day may be tested on a 24/64 choke making 22 million/day, also with over 8000 lbs flowing pressure. In your examples above, The Rex Young # 6 might very probably have tested above 20 million/day on say a 24/64 choke with flowing pressures above 8000 lbs rather than the 7700 lbs. reported on a 28/64 choke. The Sample 8 @ 7951 lbs certainly didn't miss 8000 lbs. by much. Lets just say that, because of a requirement of a daily drilling report under the terms of my leases, I am aware of wells testing over 20 million/day with over 8,000 lb. flowing pressure.

SB, a well flowing with a pressure of say 8200 psi on a 16/64" choke is unlikely to flow at 8000 psi on a 24/64" choke.

By the way, there have been only two wells reported with flowing pressures above 8000 psi with choke sizes greater than 20/64". Both were EnCana wells in Red River Parish with 21/64" chokes.

The Rex Young 6 H1 Well would likely flow at ~ 19 MMcfd with a 24/64" choke and the flowing pressure may still not be over 8000 psi.

Les, your knowlege of the play is second to none and I use your information to increase my knowlege of the play every week. In this particular case, I can just confirm to you that my information is accurate and can be used to increase your knowlege of the play. I don't mean that to be arrogant but my info is accurate and comes from daily drilling reports emailed to me.

SB, I am not doubting your information. I just didn't want people to get the impression there are a bunch of wells that can flow at 20+ MMcfd with an 8000+ psi flowing pressure on a small (16/64") choke. My original comment was just an attempt to assure landowners that a well flowing at ~ 10 MMcfd & 7700 psi flowing pressure is a good well.
