Off Topic Re-Fracking Oil Wells

[Klause]

I should add there are certain chemicals that get used... I e calzan Barazan SAPP etc... However they are used in such minute quantities... there's 80 bags of gel and 20 bags of sawdust and maybe 3 bags of chemical in a 22,000 litre mud system.

Still trying to get my head around this. Is there a difference in method between the original fracking of a well and re fracking as it slows down in production.
From what i have found and it must be true because i read it on the internet the next big push is re-fracking in today's oil price environment.
Thanks for the posts so far seem to learn a lot more here than from the propaganda websites discussing this.There is always three sides to a story around here. LOL

If the surface casing is done right. There should be no problems with drinking water. There is the odd well that is bad. I rember it circulating on a well north of eagle lake. We were having lunch in the doghouse and the Derrick hand was at he pump truck. Field sup showed up and was honking his horn. I said to boys. What's up with this guy, it's not there is oil running by the doghouse. I opened the door. And to my surprise there was. It's was coming out of the ground under the front of the rig which was on the lease road.

I obviously know more about it than you Klause - otherwise why would you highlight Barazan as one of the nasty chemicals when its only a powdered Xanthan gum polymer - Xanthan being another common food additive.

How about the methanol, the BTEX compounds like benzene, lead, hydrogen fluoride,naphthalene, sulphuric acid,formaldehyde, diesel and all the minor ones on the "proprietary" list? Many carcinogens and poisons on that list.

Allis, essentially no difference in re-fracking. Just blasting the pores open again to get it flowing again.

Why are they supposedly much cheaper to re-frack than the original frack. This according to company websites that are or will be involved in re-fracking.
This when some are claiming it is a much more involved procedure with more fluids and more pressure than the original job.
Re-fracking seems like it has a future in todays investment climate in the oil industry

Sarcasm grassfarmer. Sarcasm.


Methanol? Never used. Evaporates too quickly in high temps.


The only time nasty stuff is used is when you're dealing with invert...

Allis, I would say that refracking is considered cheaper because they are going into an existing well not drilling new. Fracking has been around for decades. They were doing it in my area in the 70's. Like Coleville says with directional drilling and multistage fracking they are able to have essentially similiar production to 6 or 8 wells with the surface disturbance of one. More efficient infrastructure, less lease roads, less flow lines etc.

Grassfarmer the zones where the fracking occurs is no where near the depth where we draw drinking water.

I have no problem with fracking of oil wells. Shale gas is another story. It is too close to the depth where we draw our drinking water and I think this is where the bulk of the problems have occurred. Unfortunately, fracking of oil wells get lumped in.

Refracting costs more than the first frank but it's way cheaper than drilling a new well....


may be a good time to invest in calfrac and haliburton and the like

Thank you guys. Was reading where Crescent Point was budgeting to do a lot of this in the future.Yes this may be an interesting thing investment wise. Sold some deep in the money calls on some gold stocks which should work out. Maybe next place is oil. Thanks again.
