• 31507, dry, CLR, Charlotte 7-22H, drilling ceased in the vertical section at 9,977 feet due to hydrogen sulfide gas presence at shakers; due to an inability to run the cement required to begin a sidetrack, the well was sealed and temporarily abandoned.

Note: #19912 and #21401 are also Charlotte wells but they are in the Siverston oil field and not part of the Charlotte wells noted above.

This is the story / press release linked above from the Oil & Gas Journal:

The Bakken-Three Forks play in the Williston basin contained an estimated 903 billion bbl of original oil in place or 57% more than in 2010 when Continental Resources Inc. estimated that the entire field would eventually yield 20 billion bbl of oil and 4 billion boe of natural gas.

The company raised its estimate of OOIP based on results of its own completions in benches of the Three Forks formation just below the Bakken.

In 2010 it assumed 577 billion bbl of OOIP in the Bakken and TF1 formations in North Dakota and Montana.

Continental floated the new estimate after testing its Charlotte 3-22H well in McKenzie County, ND, the first horizontal well to test the Three Forks third bench (TF3).

The company was first to demonstrate incremental reserves from TF1 in 2008 and first to establish commercial production from TF2 in 2011 (OGJ Online, May 22, 2008).

The 1,280-acre Charlotte unit is the first unit in the play to have wells producing from three separate horizons, the Middle Bakken, TF2, and TF3.

Charlotte 3-22H is the first well in a 14-well program that Continental plans to complete by the end of 2013 to test productivity of the second, third, and fourth benches of the Three Forks over a broad area of the play.
