• 23608, 1,303, CLR, Charlotte 5-22H, Banks, 4 sections,12 - 26 feet under the top of the middle Bakken; 2' to 10' flare; trip gas over 9,000 units; TD, 21,622 feet; t6/13; cum 229K 8/18;
• 21128, 692, Charlotte 2-22H, Banks, TF2, SWSW 22-152-99; Three Forks geologic marker: 11,273 feet; 30 stages; 2.3 million lbs; total depth: 21,358 feet; t10/11; cum 231K 8/18;
• 19918, 496, Charlotte 1-22H, middle Bakken, middle Bakken geologic marker: 11,276 feet; TD, 21,090 feet; SWSE 22-152-99; Banks, 30 stages; 2.5 million lbs; t6/11; cum 334K 8/18;

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.

Update On Zenergy's Omlid Well; The Omlid Is A TF3 Well; Huge Well

It is simply going to be impossible for me to keep track of what's going on in the Bakken. Thank goodness for readers sending in comments and Mike Filloon. I'm not sure if anyone else is providing so much information, free or otherwise.

A reader sent me this, regarding the Omlid well:

• 20761, 2,196, Oasis/Zenergy, OMLID 18-19HTF, Elidah, t4/13; cum 98K 6/14; 35 stages; 3.65 million lbs proppant;

It came in at over 2,000 bopd, and produced 17,000 barrels of oil in 28 days of April. There are three (3) first bench Three Forks (TF1) wells offsetting it to the west, south, northeast, but this is the first TF3 well in this immediate area. The nearest TF3 might be CLR's Charlotte 3H about eleven (11) miles to the northwest in Banks oil field.

Again, this is a third bench Three Forks well. A third bench.

Some data points from the geology report:

• targeting the Three Forks formation targeting the third bench of the zone
• reached total depth in 31 days
• horizontal about 11,472 vertical depth; total depth of 20,699
• the middle Bakken came in at 10,950 TVD which ended up isopaching to landing at 11,155 
• TVD and with there being plenty of room in the 3rd bench of the Three Forks formation the landing was kept the same at 11,162 TVD
• the bit began building its way down into the Three Forks formation at 11,020 TVD .. intermittent layers of siltstone, sandstone, and dolomite
• the first bench drilled at 0.5 - 1.5 min/ft with gases ranging from 286 - 2,357 units
• the bit moved down into the shale/siltstone layer of the second bench at 11,160 MD, drilling at 0.6 - 1 min/ft
• at 11,256 MD the bit moved down into top of the third bench; the top of this marker isopached to landing at 11,155 - 11,153 TVD
• the top layer of the third bench was composed of siltstone that was very distinctive compared to the other members showing to be red orange, rusty orange, light to medium orange that was chalky
• drilling at 05 - 1.5 min/ft; reading 300- 752 units of gas in the third bench of the TF formation 

One year ago, we only knew about the "Three Forks." No one really knew we were talking about the "upper" Three Forks. Now, we are into the 1st, 2nd, and 3rd benches. In some areas, maybe additional benches. And in some areas, as noted in an earlier post today, the Three Forks is going to be better than the Bakken. 

I am truly blown away. I could see CLR and EOG drilling a TF3, but seeing these smaller players do this, it speaks volumes.

In some areas, we are in the manufacturing stage in the Bakken; in other areas, we are still exploring.
