Chesapeake/Nomac Rig #17 Hits Shallow Gas Pocket-Burns To The Ground

Jan. 5th 2012 10pm

Nomac Drilling Rig #17 drilled into a shallow gas pocket soon after spudding in at a drilling depth of 900' northwest of Sweetwater, Oklahoma this evening around 6pm and burned to the ground. No injuries were reported.

Workers stated that they encountered the abnormally pressurized zone at relief time around 6pm when the relief crew was in the change house.

It was first thought that they had encountered a shallow air pocket but after testing with a "sniffer" (a device to determine the presence of hydrocarbons) the well soon caught fire.
Witnesses 3/4 of a mile to the north reported hearing a loud "boom" from their residence "and then it sounded like a jet engine was right outside our home".

When they drove down to the drill site to investigate the well was discharging fluid into the air, soon after that something ignited the gas and the rig  caught fire.

Bar Hoppers (used to increase the mud weight and counter downhole pressures) were not yet rigged up. A gas separator, chokes and a BOP stack were also on location and waiting to be rigged up and tested as soon as the surface portion of the hole was completed.

Without these blowout prevention devices in place there is little to nothing that can be done to control the well.
It's very unusual to hit a shallow air pocket in the area and even rarer to encounter any hydrocarbons at this shallow depth above the planned surface casing.

El Reno, Oklahoma based Nomac Drilling is a wholly owned subsidiary of Chesapeake Energy, one of the nations most active drillers.

Doesn't look like sufficient flow to crater much.  Need to get some heavy mud in there.

Que desgracia. Por suerte nadie salió herido, los fierros se pueden reemplazar, los seres humanos no!

Asi es.Dicemos lo mismo en  arabe: Los  fierros se reemplazan pero los seres humanos nunca jamas.  Lo importante es que no  hay herridos.

Like all accidents, it is great to hear no one was injured , we are just about to gain experience here in Ohio of the everyday risk that is built into this type of work , Keep safe, always remember those that depend on you ,and it makes safety a lot easier to master .Have a safe year and many more

Who was the consultant out there? Anyone know??

Comment by Horizon3 on January 8, 2012 at 6:18pm

Thank The Lord no one was hurt! Gotta watch out for those sand pockets in Oklahoma, they are known to occur pretty much anywhere and are too small to show up on the seismic surveys. They have claimed more than one rig over the years.
