Notes And Commentary
Let's see if the daughter wells are better than the parent well. Experts tell us that the daughter wells in shale always do worse than the parent wells.
Early production data:
- 23639, 1,482, WPX, Patricia Kelly 2-1HB, Spotted Horn, t3/13; cum 388K 7/20; off line 8/20; remains off line 3/21; back on line; cum 441K 5/22;
From the file report (one of the better file reports for discussion of the geology):
- 27 miles east of Watford City, on, or near, the Little Knife anticline
- thickness of the middle Bakken, target: 10 feet thick
- 84.7% of the well bore within the pay zone (below the current standard)
- big rig, spud: October 27, 2012;
- curve building began November 10, 2012; landed on November 12, 2012 (a bit longer than the current standard)
- lateral: began drilling on November 15, 2012; concluded, November 26, 2012;
- frack: 16 stages; 3.23 million lbs of proppant

From the well file:
Three contacts with the middle Bakken Limestone and two with the Low Gamma zone occurred while drilling the lateral section.
The first contact occurred at approximately 12,000’ MD with a total of 430’ drilled below the pay zone in the middle Bakken Limestone. This out of pay zone footage was an intentional drop made through the section immediately out of intermediate casing in order to get a complete resistivity and gamma ray profile of the entire pay zone. This was requested by operations for future reference while drilling the lateral section. Once a full profile was achieved, the borehole immediately was built in section to get back into the center of the middle Bakken pay zone.
The second contact occurred at approximately 16,000’ MD with the middle Bakken Limestone, resulting in 387’ drilled below the pay zone. This encounter was most likely attributed to bit deflection while bed lithologies were transitioning from a “flat” dip to a relatively upward dip.
Two contacts with the Low Gamma zone at Patricia Kelly 2-1 HB occurred at approximately 18,400’ MD and approximately 20,000’ MD resulting in 403’ and 133’ drilled above the pay zone, respectively.
Both of these out of zone footages were possibly attributed to bit deflection while drilling the well bore after initial builds in section to calculate bed thicknesses encountered and crossed up into the Low Gamma zone.
The difficulty in turning it over back into the middle of the pay zone was most likely from the bit deflecting off the top of the target zone.
The fifth contact was with the middle Bakken Limestone occurring at 21,200’ MD with 159’ drilled below the pay zone. Based on the response of the bit through this section, the difficulty in penetrating back up into the upper pay zone was again likely a result of bit deflection from the middle Bakken Limestone at the very end of the lateral section.
The accumulated out-of-pay zone footage for at Patricia Kelly 2-1 HB was 1,512’, representing 15.3% of the total lateral footage out of zone.
