[Agentm]

If you go back and check you will find some weeks with many more than seven in a week. Dedication is right. The posts all help in the understanding ofADI and Sugarloaf and keep us informed and up to date. It is a pity ADI don't keep us as up to date. I am sure they have to check this thread to find out the latest for themselves

he isnt a investor,, just a clown making a fool of himself,, some sort of sushi.. the thought police, and monitor of how many posts i make. and certainly not a adi holder, and certainly worth ignoring.. he just wants attention, and isnt able to control himself.

your correct i have made many more posts than that in a week,, currently i am in sleep mode zzzzzzzzzzzzzzzzzzzzzzzzzzzz............... but looking forward to being able to post as many as i want in the very near future!!

i see that TCEI is still putting through leases, just when i thought they were finished, in karnes county.. Nice!! add another pink dot to that map above!!

still liking what i see,, and looking forward to the zone 3 results in the next week or so..

 

[chance fate]

... here's a thought.. if sugarloaf is put on long term production test like the kunde well... we may see test results in a few months rather than weeks... mind you such a test would be very encouraging... but personally i'd like to see them do short tests on zones 3 and 2 then go for the prize and have zone 1 on long term production test...

Sugarloaf-1 Well
Kennedy #1H is located some 1.6 km from the Sugarloaf-1 well where fraccing and testing operations were commenced last week. Fracture stimulation of the deepest of the three zones of gas shows and log interpreted potential gas pay in the Cretaceous age Austin Chalk Formation wascarried out on 11 September. The fracture stimulation operation terminated early after a premature screen-out halted pumping after only 6% of the planned proppant was placed in the formation. The reason for the screen-out is not known.
Proppant in the well bore is presently being washed out by a work-over rig prior to running tubing to test the zone. Some intermittent gas is being recovered during this operation. The significance of the gas shows will not be known until test operations are completed. Further ASX announcements will be made as results from this test become available.

has anyone ever heard of a screen-out?? Whats that??

 

[sbop]

CRRRRAP! .... oh well another delay.... should have seen that coming. Bright side is its another buying opportunity, get another couple of pay cheques into it.
Little hard trading with out market depth though...

Gotta ask could they have told us earlier? ... obviously they diliberately held off so they could soften the blow with the news of Kennedy.

 

[Agentm]

they had decompression, so you stop.. now they have to clean up the well, log it and trace the source..

just a delay,, no damage to the formation, nothing to be concerned about. I had a quick chat with adi before and they are not concerned about the situation, just frustrating to have a further delay.

gas shows are still there.. the well is fine,, just a little bit of a mess with all the sand down there.. so wash out time!!

also kennedy 1H was spudded. nice news..

hope it helps

 

[-merry]

so... a premature screen out is basically decompression that happened to early? what could have caused it? any ideas agent??

 

[Agentm]

they wont know until they clean it up and log it..

Some intermittent gas is being recovered during this operation. The significance of the gas shows will not be known until test operations are completed.


Kennedy #1H
Adelphi Energy Limited advises that the Kennedy #1H exploration well, located in the onshore Gulf Coast Basin in Texas, USA, commenced drilling at 1830 hours Texas time on 17 September 2007. At report time (0600 hours on 18 September 2007, Texas time) the well had reached a depth of 565 feet in 17.5 inch diameter hole and was drilling ahead. The proposed total depth of Kennedy#1H is 17,570 feet (5,360 metres) which includes a horizontal section of approximately 5,000 feet (1,525 metres) to be drilled through the Austin Chalk Formation at a vertical depth of approximately 12,000 feet. The zone to be targeted by this horizontal section is believed to correlate with the producing section in the Sugarkane Field discovery well which is located some 8 km to the west of Kennedy #1H.
On a trouble-free basis the prognosed drilling time for this well is about 45 days.

Sugarloaf-1 Well

Kennedy #1H is located some 1.6 km from the Sugarloaf-1 well where fraccing and testing operations were commenced last week. Fracture stimulation of the deepest of the three zones of gas shows and log interpreted potential gas pay in the Cretaceous age Austin Chalk Formation was carried out on 11 September 2007. The fracture stimulation operation terminated early after a premature screen-out halted pumping after only 6% of the planned proppant was placed in the formation. The reason for the screen-out is not known. Proppant in the well bore is presently being washed out by a work-over rig prior to
running tubing to test the zone. Some intermittent gas is being recovered during this operation. The significance of the gas shows will not be known until test operations are completed.
Further ASX announcements will be made as results from this test become available.

if they are running tubing to test the zone after clean up does it mean that they've blown the frac operation? i.e. they can't just clean up and frac again? hope the shows are actually useful...oh well... at least there's 2 more zones to go... hope they get the frac right in those two operations...

PS... don't bail out yet especially with all the confusion... will just stand back and let those that know what's going on bail out instead.... ;-)

i had no idea they couldnt frac any further,, thats news to me chance..

my impression when i spoke to adi was that they are cleaning it up, then logging it, the sands are slightly radioactive, so they can see where it may have given way.. if its a failure of the sqeeze cement then maybe they will do more remedial works and go again..

i am very happy they have the K1H well spudded, the set back on the frac is one thing, but TCEI going after the sugarkane is completely another..

they must have good test results at kunde 3 and are happy to go after the sugarkane again!!

i dont view the sugarkane as just being confined to our 20,000 acres, nor to it being confined to the 600 odd acres conocophillips has, i see it as 200,000 acre play.. and its obvious TCEI has enough data to be confident on the suagrkane..

they wont know until they clean it up and log it..

ahhhh okay.. I just thought that maybe you knew common causes for such a thing or something like that.

 

[Agentm]

ahhhh okay.. I just thought that maybe you knew common causes for such a thing or something like that.

you have to wait for the test results for the multi tcf answer..

its obvious the message is put there and never needed to be added.. its something you add if your trying portray a picture in my view..

gas shows are gas shows,, it means nothing,, they are saying they have perforated and have 6% frac done when they stopped, and are recovering gas... make your own mind up why its there.. i sure as heck dont think its mentioned for nothing!

 

[chance fate]

... agent... i'm not an expert on frac or anything... but my understanding of a screen-out is that the frac proppant has been squeezed as hard as possible into the formation and fraccing has stopped because the particles in the proppant have built up to the extent that no further fluid can push on into the formation - without raising the pump pressure to a level where it damages equipment... i don't know what remedial work could be done in that situation... maybe back flow and see if any of the backed up proppant comes out?? i'm only guessing it may be possible to get some idea of reservoir performance from testing the limited fracced zone now.... that's why i'm assuming they're running tubing to do the tests directly now and then move on... maybe the permeability is good enough already... but if that is the case why bother fraccing?? zone 3 in practice doesn't look good to me now despite it's potential... maybe kennedy 1 can pick it up i.e. drill a little deeper into zone 3 back up from there and then kick off the horizontal section higher up...??

PS whoever is bailing out of adi and eka seems to be buying into AUT... which hasn't suffered from this announcement????

hrmm.. not sure if we're talking about the same thing... i was thinking more about common causes for premature screen-outs during fracture stimulation... like if theres multi tcf gas waiting to explode out of the drillhole or something of that sort : (i.e. good news) hehe

chance

i will wait for ADI to announce again whats happening.. All i know is that the situation is a "nuisance" and i was told it was viewed the in terms of "nuetral" as to having any any impact on the progam on the well,, i understood they were cleaning up the sands then running logs to diagnose the reason for the sudden decompression, something gave way, so they need to check it.. you can guess all you like, but it wasnt as you describe, i was told decompression, you maintain it was inabilty for fluids to run as a result of blockages??

why not ring chris at ADI and get some idea,, your obviously good at understanding the processes of it, and he would gladly help you understand it.. but from what i gather the well decompressed, not compressed, and they stopped.. rest will be found out in the coming days..

The best news i feel is the spudding of the K1H well.. its not being discussed currently buy i view it as significant in terms of ADI pathway into being a producer, i am convinced the horizontals are the focus of the development of the chalks, and as much as the testing of the chalks is delayed, i still maintain TCEI is not progressing on without talking into account all that was learned in the kunde wells,

the fact kunde 2 is also drilling directionally makes it very positive news this week.

 

[chance fate]

agent... not sure if i hope you're right... but anyhow a neutral outcome would be ok for now... if the well decompressed that could mean there was a screen out followed by the (remedial?) cement job giving way as they increased the pressure.... so then i'm wondering where did the fluid go?? and if it did give way maybe the gas shows are coming from another zone via the broken cement.... maybe they're going to run wireline logs to check the cement integrity??... oh well.. we'll find out in due course.... i'm also like you happy Kenedy-1 has spudded without results from sugarloaf1 roughly only 30 days until we get to depth... then 15 for the horizontal bit.... doubt all the SL operations will be finished in 30 days for them to make drilling decisions based on SL1 results... so they're going into it with some confidence....

screenout

1. n. [Well Completions] ID: 2802

A condition that occurs when the solids carried in a treatment fluid, such as proppant in a fracture fluid, create a bridge across the perforations or similar restricted flow area. This creates a sudden and significant restriction to fluid flow that causes a rapid rise in pump pressure.
2. n. [Well Workover and Intervention] ID: 4759

A condition encountered during some gravel-pack operations whereby the treatment area cannot accept further pack sand and a sudden increase in treatment pressure occurs. Under ideal conditions, this should signify that the entire void area has been successfully packed with sand. However, if screenout occurs early in the treatment, it may indicate an incomplete treatment and the presence of undesirable voids within the pack zone.

maybe read lotire on advfn,, and your definitions fly out the door..


i will repeat this again, phone adi if your unsure about things..

Lotire - 19 Sep'07 - 08:32 - 56876 of 56886


loxley your an idiot give me patients with muppets like you.


A screen out is when the fluid leaks away due to decompression and the proppant is left behind being to heavy/viscous to pump you wont find that in any google page you will look up and C+P because these are my own words.....




hope this helps you guys a little.. its not always the case that a google answer fits the picture so to speak..


as i said before,

the best news today was the spudding of kennedy 1H well, its not being discussed as all attention is fixated on the screenout.. once its mopped up they well will be logged and then we can expect an announcement.

hope this helps..

 

[chance fate]

...agent ... I think Mike Z might trump that one, his definition comes from a higher authority i.e. the Gods of oil field things (!? except halliburton and maybe Baker and.....) Schlumberger Glossary at http://www.glossary.oilfield.slb.com/Display.cfm?Term=screenout

...but can definitely see why decompression would occur... on the down stream side of the screenout the pressure would indeed decrease as the proppant particles are holding back flow... but you wouldn't see that at surface straight away... only after you stop pumping... another thought is fraccing may have started going laterally in the area upstream of the screen out i.e. not in the cement but in the formation but closer to the perforations...

...as you indicate we (and it seems adi) can only speculate what is really going on at this stage....... but personally a bit rattled today... at this moment i've got a feeling that the chalks in this zone have very poor permeability....

its great to see the expert opinion on the geology from a few sentences in the announcement.. and a google reference.. see lotire answer above....

I again stress to everyone to ring the management if your unsure about the announcement.. dont believe all you read, theres a great deal of misinformation being thrown around deliberately right now to shake the sp up in my view!!! watch out!!

now again i think the single best announcement this YEAR!!!!!! has just been announced, as much as everyone is dead keen to ignore it..

KENNEDY 1 H spudded,, its a horizontal well currently permitted to drill into the PROVEN sugarkane play. current estimates for the suagrkane zone is 600 bcf to 1TCF..

hope this helps

I shall attempt to summarize the above points as a person who worked for Halliburton doing frac jobs for many years.

Hydraulic Fracturing is the process of creating a fracture in a porous medium by injecting a fluid under pressure great enough to cause failure in that medium.

Proppant (spherical and rounded Sand or synthetic sand of average size about 0.50mm) is mixed with the fluid at surface so that it follows the fluid into the fractures and on pressure release remains trapped in the fractures allowing permeable flow back into the well bore greater than before fracturing.

Fracturing is an extremely complex procedure with many variables, but the essential items are that the fluid MUST be kept moving in order to maintain proppant mobility, and the proppant concentration must not be allowed to increase above optimum. The result of either the fluid slowing or the concentration getting too high will cause proppant drop-out or 'screening out'.

Screening out can happen anywhere in the well bore or in the tubing or in the formation. It can even happen at surface in the pumps or the mixing blenders. Once proppant becomes immobile it is effectively a solid and can only be washed out slowly.

There are many reasons why a planned fracturing job can stop early :

-the design was incorrect and the formation was not able to fracture as expected and the fractures did not materialize. One always starts a fracturing job with pure fluid to initiate the fractures so the proppant has somewhere to go once introduced. If the fractures are only small - sufficient to take fluid but not much proppant - then you will get early screenout.

- Too high a concentration of proppant added at some point.

- A sudden increase in pressure forcing a slowdown in fluid pumping velocity allowing proppant to drop out and screen off the fractures. (This is what happens towards the end of a fracture job as standard)

- a sudden down hole drop in pressure from a cement bond failure, or a screen failure or a massive fracture being created which allows the proppant to 'fall' rather than be pumped or carried thus causing screen out.

- Poor perforating of the casing which allows fluid through but very little proppant.

Etc etc and hence why they do not immediately know.

Fracturing is such a common thing these days, especially in Texas, with immense experience that an error in design is extremely unlikely. Screen outs are also very common and mean nothing but just that - a screen out. They will clean it out and try again or test the well as is to attain essential information.
It is always possible that the fracture already created, although it only took 6% of the design proppant, could have overcome the lack of permeability to the well bore and the well will flow satisfactorily for these initial testing purposes. Early indications of gas in the returns is obviously encouraging.

Nothing to worry about imho dyor etc.
