Earlier this year I wrote a blog about Brighams’ then new well the Jack Cvancara 19-18 #1H and how it had the 2nd highest IP (24-hour peak flow back rate) in the Bakken at 5,035 Boe/d, second only to Brigham’s Sorenson 29-32 #1H that peaked at 5,133 Boe/d (Brigham Takes Gold and Silver in the Bakken). Recently there has been a small disruption of the top spots as it relates to Bakken IPs with Brigham’s Clifford Bakke 26-35 #1H now taking 2nd with 5,061 Boe/d. Brigham now has the 1st, 2nd, and 3rd highest IPs according to their latest operational update.
In an effort to dig a little deeper we will look at 6-month cums for wells that have produced at least 6 months in the Bakken. Take note that our 6-month cum analysis is not taking into account important factors such as well location as it relates to Bakken sweet spots, quality of acreage, operator learning curve, etc. We are simply looking at these wells purely on a play bases. In looking at the top 100 wells based on 6-month cum, here is the breakdown by operator:
Brigham has 3 of the top 100 wells based on 6-month cums while EOG has the most with 46 and Whiting has 30. Brigham’s 3 wells are ranked 54th (Sorenson 29-32 #1H), 78th and 93rd while EOG owns 1st-3rd, Whiting has 4th, EOG has 5th-7th, Whiting has 8th and back to EOG with 9th-10th.
We will now look at average 6-month cums. The following is an average 6-month cum table by operator with Windsor Energy Group at the top (note: Windsor only has 1 well which is 23rd on the 6-month cum well ranking list). The “% from Top” column takes the highest average, Windsor Energy Group, and calculates a percentage for each operator against Windsor. We can see that Brigham is at approximate 74%, while EOG and Whiting are at 93% and 87% respectively.
Now, this blog is not meant to discredit Brigham’s success with the highest IPs in the Bakken and we are missing 2 of the 3 highest Brigham wells in our 6-month cum analysis (Clifford Bakke 26-35 #1H and Jack Cvancara 19-18 #1H) but it does go to show that even though wells with high IPs typically have higher cums, the highest IPs don’t necessarily equate to the highest cums.
