Frac Stack Blowout In Texas Panhandle-Amazing Photos

March 18th, 2013

We have received the following information & amazing photos in email

"While were pumping at 8500 psi in a Granite Wash completion the 7” production casing parted, the surface casing parted above that, launching the frac stack (hydraulic valves and Stinger isolation tool) and all frac iron - landing in the middle of the Cased Hole truck.

My guess here is the casing parted at the connection from cold water shrinking the unsupported pipe (un-cemented) and putting it in severe tension, making the casing fail at the collar connection. Keep in mind it parted on the 7” and immediately failed the surface casing connection with the upward force. Quick and easy math of the pressure over the surface area upon parting is 327,250 lbs upward force!

There were no fatalities. The Cased Hole engineer was in the recorder cab sitting against the wall that remains standing when the iron landed, only suffered a concussion and was the only injury on location."

I've been waiting to see more pictures of this. Scary!

Why was the cased hole engineer in the truck? You notice it didn't say that the companyman was in there with him.

That's bad At least no one was hurt. But s*** happens in oilfield just like anywhere else does.

I am so glad there were no injuries. This is what dangers come with the job . It isn't a nice reality. You all have my admiration for what you do and deal with daily.

Why was the 7"casing not cemented to begin with before fracing that well

I agree with Kenneth. Where was the cement?

Incidents such as these are giving our industry a bad reputation and causing enviornamental damage. In the race to find and book hydrocarbons, the operators are neglecting the Hazids/Hazops and the service companies are pushing their luck. Not knowing all the details of the construction of this well, the end result speaks for itself - this was not a candidate for a frac.

Not good


Comment by Jane Pennell on March 20, 2013 at 9:44am

Why would they be fraccing with cold water?  As a general rule, water is 90° at pump time.

Comment by Roger Payne on March 20, 2013 at 3:21pm

I am in agreement with Jane here, Frac tanks are usually heated. then picked up run thru the blender tub, then the missile then pumps, down treating line to the well head. Kenneth and Jim are spot on ! Where was the cement.

Where is the CBL?????? and how can you frac without one looks like Stinger tool had a good seal glad no one was injured 

Comment by richard creley on March 21, 2013 at 3:25pm

Glad to hear no one was injured or yet killed, but one must ask. "why was it not fully cemented"?,better yet someone needs to go back and get better trained on reading a caliper log,my bet is they probably had plenty of cement for a normal,10%washout hole and not a 80-90% washed out hole

Screen out, PKR unset, Jump for the string & Frac head,
The same situation happened in Egypt, but not worse like this

Comment by Ikram Shafi on March 26, 2013 at 3:18pm

Some time  operators and services companies both hide the critical facts due to different reasons that become the cause of such accidents, how possible no one have checked the CBL and casing integrity, pictures are showing  that the well was not a candidate for frac job.

Odds on that since this was 7" to surface, it was a tie back job from a 7" linerdownhole, hence there would be no cement back to surface, just at the liner top and around the tie back shoe.
