Utica well blowout under control, Magnum Hunter Resources says

HOUSTON -- Magnum Hunter Resources has reported that the blowout of the company's Utica shale well, the Stalder 3UH, located in Monroe County, Ohio, which occurred on Dec. 13, is now under control and the well has been temporarily capped.

Wild Well Control has successfully replaced the Stalder 3UH's well head assembly. Due to the gas content being ~97% methane, there was no evidence of environmental damage to the immediate area as a result of the blowout, the company said in a statement on Dec. 23.

Initial well control operations involved excavation around the well head to properly evaluate the condition of the well head flange and night cap. Fresh water was continually sprayed on the well head to reduce the chance of ignition of the natural gas. Initially, attempts to push the night cap back over the flange with a track hoe and a crane were unsuccessful.

Wild Well Control then began the process of replacing the well head assembly. As part of this process, the individual casing strings were cut in a number of different places. The new well head was then installed and the well was shut in on Dec. 23. The pad site will now be brought back to its original condition, and the company anticipates that all wells on the Stalder Pad will be placed on production sometime in January 2015.

Magnum Hunter continues to believe that there has been no damage to the overall structure or integrity of the Stalder 3UH well and that the loss of control of the Stalder 3UH well has not affected Magnum Hunter's three other Utica shale wells (the Stalder #6UH, #7UH and #8UH), and the one Marcellus shale well (the Stalder #2MH), all located on the company's Stalder Pad.
