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.

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.

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)

Here's the specs at the bottom of the logs

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."

See a doctor. Get rid of it.

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?

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.
