The performance of a trio of step-out wells drilled by Continental Resources Inc., one of the biggest oil producers in the U.S., has again proven that optimized completion designs are working in the Bakken.August 5, 2019, presentation: on the fringes of the Bakken --
“As expected these three wells are outperforming nearby legacy wells by 80% to 110% during the first 60 days and preliminary estimates show these wells are delivering up to 100% rates of return,” Jack Stark, the company’s president, said on an earnings call April 30. “This is great news for our shareholders as we can confidently say that the value and performance of our inventory of approximately 4,000 Bakken wells continues to grow. We can also say that the core of the Bakken … just got bigger.”
Two of the wells, both in North Dakota, recorded 24-hour IPs of at least 2,400 barrels of oil equivalent per day (boe/d), while a third—in Montana—flowed 1,680 boe/d.The wells were drilled in the far western and southern parts of the company’s legacy Bakken acreage. So “we feel good that the areas in between are going to respond,” Stark said, noting Continental is also pushing farther north.
This comes as the company moves deeper into multizone unit development across its vast oil-rich Bakken acreage, having already completed nearly 200 optimized developed wells since early 2017.
Completion designs for the three step-outs varied based on the area, but the company said it essentially used closer perf cluster spacing and more stages and proppant than it has used historically in the areas.
- far, far west: Montana's Baird Federal 2-34H, 1,680 boepd 24-hour IP; outperforming legacy well by 100% at 120 days
- far, far southwest: North Dakota's Burian 4-27H1, 2,400 boepd 24-hour IP; outperforming legacy well by 75% at 120 days
- clearly outside tier 1 core: North Dakota's McClintock 8-1H1 2,440 boepd 24-hour IP; outperforming legacy well by 145% at 120 days
- years ago, Lynn Helms suggested a Three Forks well next to a middle Bakken well is likely to be better than the middle Bakken well; note that both of the North Dakota wells were first bench Three Forks wells
- also note: the third well noted: it's production is outperforming the legacy well by 145% at 120 days
- Bakken was selling in the 20's during the Saudi Surge just a few years ago
- Bakken: now selling in the 40s; much better takeaway capacity, cuts transportation costs

The wells:

- 35538, 1,833, CLR, McClintock 8-1H1, Pleasant Valley, t2/19; cum 117K 6/19;
Note:
- "chronologic" number for #35538: #8
- in less than four months, the newer well has produced 50% of what the older well has produced in seven years
- well costs have come down significantly over the last seven years -- seven years -- yup, it's been that long between these two wells
