Pistol Drilling Rig #4 Pulls Crown Down Twice In April While Drilling For Sanguine Gas Exploration

Pistol Rig 4 Pulls Crown Down For The Second Time This Month While Drilling For Sanguine Gas ExplorationApril 28,2012
 Pistol Drilling Rig #4 has pulled the derrick in for a second time this month on this 900hp Compound Rig while drilling for Tulsa, Oklahoma based Sanguine Gas Exploration.

This  second incident occurred at the same Sanguine Gas Exploration location in Wheeler County, Texas as a previous April 2nd incident that destroyed the rigs mast.

 In the April 2nd incident one worker was slightly injured. We have not yet been able to confirm if there were injuries involved in this accident.

Reports from those working in the area indicate that Pistol Rig #4 had just finished repairing damage to the rigs mast and possibly replacing the substructure. Workers were in the process of trying to free the stuck pipe from the previous accident when the Crown Block buckled near the Monkeyboard around dark on April 28th.

 Attempts to reach Woodward, Oklahoma based Pistol Drilling LLC have been unsuccessful this evening.

In the April 2nd accident Drilling Ahead reported that Pistol Rig #4 was picking up to make a connection @ 12,934' in tight hole conditions 9.5 miles north and 3 miles west of Texola, Oklahoma just a few miles into Wheeler County, Texas.

We will post additional information as it becomes available.

I hope no one was injured, but is there no calculation to know the maximum weight this mast derrick will carry twice means some thing is wrong with the engineering work on this rig

This is nuts, I want to see some info on both of these derricks. It seems (my opinion) that some one doesn't know what their derrick is rated for, doesn't care, or they have some junk iron. I mean what are the chances of pulling it in twice on one rig??? And then with in a month on the same location????

I do hope no one was hurt though.

It wouldn't be the first rig I have seen with a bad weight indicator.  "but the pason only showed 200K", but the Pason is calibrated off of the dead line indicator and it is a computer....only as good as its data!

I'm thinking on unappropriated operations because the mast was repaired and raised up. Any problem about junk materials or welding should be showed on that raising.

My first question would be who approved the repairs.  In Canada any repairs to a Derrick must be Certified by a P Eng before it is put back into service.  Aren't the rules the same in the US

First off no driller should be going off of Pason. Now before you chime in and try to give me all the BS on the new generation rigs (joystick), be patient. I have commissioned a lot of rigs, mainly because I am hired to do so, and ever drilling contractor needs a P.E. Seal to sign off on design and structural integrity. ANd in the era of ISO 14000 & 14001 it is a requirement to do business world wide. 

I have commissioned several of the new Ensign built, ADR rigs, and they have an onboard computer system known as PICO, and PICO is the OS that physically tells the rig what to do, (pick up, slack off, apply the brakes, pumps on, pumps off, rate, everything, etc, etc ,etc) Now PICO relies on PASON to gather information as to what is physically happening on the rig, (WOB, SPM, block speed, everything) Now here's the kicker.

Both of these computers' software is written in different code, thus they speak different languages. So you have two different computers that speak two different languages that perform the two most important acts on on the rig. Train wreck waiting to happen. There is a needle type (analog appearing) weight indicator. It's about eight inches in diameter, and in the case of an ADR 1500 goes up to a million pounds literally. It looks nothing like a typical Martin Decker weight dial as well. 30 KLBS barely moves the needle. This is terrible when you are making intricate operations like setting mechanical packers, or trying to J-IN or J-OUT of any type of down hole tools. 

Also we found out the hard way that these two computers communicated to each other via WITS, through another computer that acts as a translator between the two. To me this is an entire cluster F---, and I have refused to sign off on design many times unless they come up with mechanical/analog contingencies for this. One simple fix we found was to hang off a traditional Martin Decker weight indicator, readily available from MD Totco, so the driller can see actually how hard he's pulling, and two, a whole lot more sensitive weight indicator, that is ten times more reliable. And hopefully avoid train wrecks.

Not sure any of this applies in this case with this Pistol Rig, I lean more in the direction of structural integrity of the mast, and question the last two inspections. I can't honestly believe that after being pulled in once already that it could have been repaired and PROPERLY inspection in that time frame, NO WAY. You would have to sandblast all the old weld areas and then magnaflux and black light the entire mast, that alone can't be done in this timeframe, let alone the repairs prior.

Just my two cents, and it won't buy you a Skittle.

Hope for the best . its god grace that no one is injured .

I'm interested in hearing what comes out of this. It's going to take some time to cut through all the CYA, and get to the facts though.

i wonder sometimes when driller's don't pay attention to the weight indicator it sound's like someone was asleep at the wheel. i pray no one was hurt. and i would surely make darn sure when repairs are made that several professional welding and structural inspectors OK the work before any operations start again. i haven't worked on a rig in years. but when i did i sure did pay attention to the weight indicator and the sound's the rig was making. god bless everyone.

The information I have is that the mast was not repaired-but replaced with a used mast.

I don't know Mike, but when your working stuck pipe and pulling over in general, there is usually a Pusher and company man in your ear...just saying!

Just added some updated photos taken 1 hour ago. (see the original post)

Does anyone know what size drilling line they was running, how many lines (looks like 10 in the picture), the rated static hook load, what kinda derrick and its rated capacity? Wonder if they just pulled the derrick out of the bone yard, slapped some paint on it and rigged it up or if like others have suggested that they didn't pay attention to the weight indicator, but you know what you have in the hole so you should be able to figure out what it should weigh and see if everything matches up, I mean you have to do it to figure ton miles anyways so at least the pusher should have known and could have matched it up because after pulling the first one in, I know I would have been all over them drillers and myself to watch that weight, I'm just interested in finding out how they ended up pulling 2 derricks in and what factors led to it. It would seem to me that there needs to be some big changes coming for that company.
