How does this well log look?

That's the basal oil creek in Pauls Valley.

It's was logged August 18th (Friday) and everyone seems to like it. I have quite a bit invested in it, but this stuff is a greek to me.

I guess my question is, how certain can one be at this point. Until it's on line, there's no way to tell for sure or is there? The driller and the geologist seem to be pretty high on it.

What rolls down stairs
Alone or in pairs
Rolls over your neighbor's dog.
What's great for a snack
And fits on your back
It's log, log, log!

It's lo-og, lo-og,
It's big, it's heavy, it's wood.
It's lo-og, lo-og,
It's better than bad, it's good.

Everyone wants a log,
You're gonna love it, log
Come on and get your log,
Everyone needs a log...

BY BLAMMO!

looks you've got about 14 CNPOR's at 4034.

not bad.

How many units of gas are in the returns? Lithology? What's the porosity?

I have a Compensated Neutron/SSD Micro log
and a Dual induction log

I'll try to find out more.

I know they are going to perf at 3932 and it's a 18 ft formation with oil and gas. Beyond that, there's a lot of numbers at the bottom of these logs. I feel like Tommy Callahan "just rotating the girter...."

I'll defer to Mongo on this...he's the expert on reading the logs...I only collect the data.

[SoonerBorn68]

I went over to the mudlogger's trailer & showed him the graph. He told me that with the low gamma counts it's sand. He said he'd bet it was porous sand, but couldn't be sure without knowing the rate of penetration (ROP). He said it looked like the spikes on the right were promising but couldn't be sure if it was oil or gas. The Pauls Valley area can produce shallow oil or gas wells in that sand. If you'd post the mudlog report he said he'd take a look at it.

Agree with you. ROP is the best way to tell porosity. Faster ROP=Greater Porosity=Possible Hydrocarbons= Cha-ching. I really only use the gamma for naming formations' TVD(true vertical depth). Get me a copy of the mud log and I can probably help out more. Lithology descriptions and tests done to the samples can tell what kind of hydrocarbon you are in.

[oilmud]

You'll know when they shoot it. Some of that oil creek is wet, hope yours is not.

OK, here's the front page of the log

Here's the same formation on the other log (Compensated neutron/SSD)

Mongo should be able to figure these logs out. Looks to me the gamma was done as an open hole log from a wireline truck.

[SoonerInFla]

Ha! He said " rate of penetration."

You have pretty good porosity there with neutron crossover. The only real area of concern for me is the amount of neutron crossover. It could easily indicate a depleted reservoir. You don't need the ROP for porosity, but it is a good backup tool to read against the neutron/density curve. You could also post the microlog (indication of permeability) and the resistivity curve which would tell us whether there is a large amount of water present in the reservoir. Did they happen to lose any fluid while drilling through that reservoir? That would indicate lower pressure in the zone (i.e. depletion). Also, did they happen to take any reservoir pressures in the zone during the logging operation?

[OUDoc]

You guys playin' cards?

[1stTimeCaller]

are you participating in this well?

I did in a well a few years ago and made my investment back in two years but the more I've learned about them since then the more I'm scared to participate again.

[Mongo]

Sandstone formations in OK have had a good past. Most are well sorted and and unconsolidated/unconformity which is ideal for great porosity. Loss of circulation can point out the low pressure of the zone, but it can also be a good thing.

I primarily work in eastern OK in the Hunton lime/dolemite. This particular formation is a low pressure area. I have worked may a well when we have lost total circulation. Prior to the loss, the gas reading were around 500 units BGG(background gas) with spikes up to 750 units. One well, when it went online for production was producing 700 barrels of oil/day plus 2 million cu/ft of natural gas.

My best advice, if you can, go talk to the mud logger about units of gas and sample shows.

Thanks to everyone for their info. I know it's impossible with a few logs and stats to accurately guess, but I appreciate your input.

I should find out Fri/Sat when they punch this pig, I'll let you know.


Thanks again

He is right about gas shows in the well. Lost circulation can also be a good thing except where it relates to reservoir damage, and with that kind of porosity it should not be much of a problem. However, without knowing a ton more about the history of the area and comparable offset porosity and timing of new drils, it is hard to tell you how successful it will be. Even the best looking zone can produce nothing if it has mostly been produced by offsets.

I tend to invest in very selective prospects when I do invest, and generally my payouts are in the 5 month to 1 year time frame. Two years though (for 1tCs prospect) is considered more than acceptable by most companies though. Oil and natural gas is not for the faint-hearted, and the more you know about the business (like any business) the easier it is to invest with confidence.

Well, they finally perfed the casing 2 days ago.

It's 4,000 feet to the target zone and they shot 4 holes in it and had the casing full of saltwater to the top. They did not have any tubing set, just 4,000 ft of casing filled to the top w/ saltwater.

They told me there was no way in hell the bottom hole pressure could push anything out thru 4 inch? casing. Well, it bubbled for a second and then water started spilling over and then all hell broke loose. It shot saltwater and then oil 80 feet into the air. It covered everyones cars, the tanks and landed up to 60 yards away.

After it calmed down a second they got a choke on it and ran it to the tank (through the casing) After that, they did several 10 minute and 20 minute tests while it flowed through the casing. It was averaging 21.5 barrels per hour. They've shut it down for the weekend and plan on setting the packer and tubing on Monday to test it.

They said they can't even guess what it will test thru the tubing, but more than likely it will be choked back regardless.

Seems pretty good so far.

that's hella good. Most OK oil wells are marginal wells in that they produce 4 bbls/day

Ditto. That is what I was going to say.
