Smaller Chokes Validated by Petrohawk

I have beaten this drum many times before, but now it seems to have some traction from one of the biggest "how big of a flow rate can we announce?" operators.

During 2010, Petrohawk plans to expand its use of restricted rate production practices in the Haynesville Shale, which has already been accounted for in the Company's 2010 production guidance. For wells brought on under the restricted rate program, initial production rates are expected to average between 7 and 10 Mmcfe/d. Delineation wells will continue to be produced under normal production practices (standard choke size of 22/64" or 24/64"). Based on the results of a 2009 pilot program, Petrohawk believes that in certain of its Northwest Louisiana development areas, wells produced from a smaller choke size may produce approximately equivalent amounts of natural gas in a twelve month period as a well produced on a standard choke size. The Company believes that its restricted rate practices in some areas may create a more stable future production base for the Company and could result in higher EURs compared to neighboring wells produced under normal production practices.

I believew one must add the Thorn Lake and Swan Lake fields to the Elm Grove as Ground Zero.

anybody heard anything about Micro Seismic Inc's analysis/monitoring of the Haynesville and fractures and performance

I wondered what the production flow rates would be. Is 7 - 10 Mmcfe/d the same as 7,000 - 10,000 mcfe/d?

Edward - Yes. M - Thousand and MM - million.

Thanks. Clearly I'm new at this.

Hello, Edward. We were all new here once upon a time. Welcome.

We have long known that the high rates that are making the headlines of companies concerning the productivity of the Haynesville shale are not sustained rates. They are are displayed to attract investors. As a Reservoir Engineer, I only reckon with the First-Thirty-day-Average Rate. i,e The initial production rate is meaningless but good for the purpose of comparison.

I am glad that we have finally paid attention to the damage that is been caused to this unconventional reservoir at very high drawdowns.

As you know, I am not very fond of making the glib comment, but how many times does the industry have to teach itself this particular lesson? One would think that this particular variant of the 'young bull, old bull' story would have been put down in an industry handbook at some point, particularly with dealing with brittle, hard and/or impermeable source rock.

Spontaneous IP's grab headlines. Pressure maintenance and sustainable flow rates wins the race. Too many good wells get ruined by operators trying to blow the doors off.

This is one STR well that's on a 14/64 choke. Seems to be doing alright so far.

Did anyone ever decide what a 80 choke is?
Permalink Reply by Muddigger on February 28, 2010 at 15:06
An 80 choke would be read on a 2 inch seat and stem and would be an 80 thousands opening. 48 ck = 3/4" opening, 60 ck = 1" and so on. A two inch adjustable choke goes up to 120 ck.
