That's the beauty. Re-entering an existing hole. Here is the example I posted before.

The company I work for just drilled and
completed a well in Wyoming for approximately 650k. 7700' frontier well. We are also
going to re-enter an old Muddy well, the Muddy being deeper than the Frontier, and
re-complete the well in the Frontier. Cost approximately 70k. As you can see that is
quite a savings. They would not re-enter a "played out hole". That's what the imaging is for to determine that very thing.

Capital recovery is much less.

Regards,

bob

I actually have some experience with this. I took a class on petroleum recovery in college. Also I did my senior project for Texaco...anyway....

I have to make this _really_ brief cause I am at work and this could be a longgg post. But I will try to summarize and get the jist across.Sounds like someone else can elaborate/correct ...

Basically, oil doesn't just squirt out of the ground...(sometimes but rarely and not for very long)... so you have "injection wells" that you use to pump stuff(steamy, soapy water) into the ground and then pump the oil water mixture back out,seperate out the water and sell the oil.. The better your soap the more oil you can recover. Also, sometimes by moving your injection points you can get more recovery.

And sometimes oil drains back into a "field" so a well that sits for a couple of years will become productive again...

This is probably oversimplified, but if you want more info there are books... ;)
