I have a question on the Crosby well, number 251932, in Vernon Parish.  The last post for this well on Sonris was:

11/06/2019  Drilled 12 1/4" hole to 14,901'; stuck; backed off @ 14,755 and worked stuck pipe; unsuccessfully.  

my question is can this well be salvaged?  or is it unrepairable?  Thanks to anyone who can answer this.

Yes they can either set a whip stock and drill around fish left in hole or set cement plug and drill around as well. It’s pretty common to side track around a fish left in the hole.  Rather then spending the extra time and money trying to fish out bha. 

Thank you for your answer.  It sounded pretty bad.  

Thx for reply Joshua..

I see where sonris added a few more words to end of post dated November 6:  Free point and prep to run 9 5/8” casing. 

Thx DC

Free point will identify where the "fish" is free and not stuck. Knowing that, they can "blow off" the fish (cutting the fish at a point above where it is stuck) and pull the "free pipe" out of the hole. Looks like they then plan to run the 9.625" casing before doing any sidetrack work.

Adding a lot of cost here to salvage using this wellbore - but better than abandoning the hole!

Thx RM,, hope they can salvage and move forward. 

They should be able to move ahead - for a price! Operators do this all the time.

It takes a LOT to totally junk a wellbore and make it useless! Just cure the problem with time and $$$$$$$$$$$$

Twenty years ago in nearby in Beauregard Parish the infamous Crosby 36 was drilled for the AC and got jammed up with junk downhole. God knows there were various attempts to fish it out but it is still down there. What else is down there was the subject of much speculation at the time, prompting the fishing expeditions post mortem. The lessee declined to  move over and spud another well. 

I am betting that extended fishing operations were tied to need to recover certain downhole equipment that had radioactive materials. Like certain logging tools.

Operators are "forced" to expend MAX effort to recover these types of tools for obvious reasons.

And after all that "lost money", no wonder operator opted to not try to drill a new well.

Thanks for posting. It is tough drilling country here due to pressure, lost circulation and temperature.

Plus the various geological gremlins that inhabit the subsurface world!!!!!! LOL

Speaking of pressure, the well one unit to the north of the well under discussion required a 20,000 lb. blowout preventer whereas normal for  the Sugartown/Sugrue/Pitkin Field AC wells was a ten thousand lb. BP. The operator almost lost it before some very heavy mud arrived from Houston. I never saw a truck driver so hiked up on dope as that guy. But he delivered, just in the nick of time.
