Target Zone Efficiency -- October 27, 2015

Some time ago (if I find the link, I will post it), I opined that CEOs of Bakken operators will expect that their roughnecks and geologists keep the wellbore in the target 98% of the time or better. Anything less will result in a bit of discussion.

Note the percent the wellbore was in the target in these two wells reported today, just as an example:

• 27001, 1,428, HRC, Nelson 157-100-25A-26-3H, Marmon; it appears gas averaged about 2,000 units along the lateral; spiked to near 3,000 units; in-zone percentage and footage are 77.7% and 7,780 feet; the target was a 10-foot window between 13' and 23' below the top of the middle Bakken; 34 stages, 4.1 million lbs, t4/15; cum 64K 8/15;
• 29839, 1,033, CLR, Maynor 1-35H, Crazy Man Creek, a 3-well Ecopad; an 11-foot target zone situated between 16' and 27' beneath the base of the upper Bakken shale; alternately, a 14-foot target zone between 15' and 29' feet beneath the upper Bakken shale; ; total gas was static, ranged around 800 units but 2,000 units at the toe; remained in the target zone for 6,009 feet, 64%; 30 stages, 3.5 million lbs, t5/15; cum 61K 8/15;

A Note to the Granddaughters

Several years ago, our middle granddaughter -- this would have been when she was in kindergarten or first grade -- won the prize for guessing the number of jelly beans in a jar at some school contest when she was in school in Belmont (Boston), Massachusetts. She and I sat down in front of the jar, counted the beans on the bottom "row" and then counted the "rows" and then provided an estimate. She won; I've long forgotten the specifics. (By the way, when they were announcing the results of the various contests to come up to collect their prizes, Olivia was standing on the steps up to the stage before the announcement, because as she later told me, she "knew she was going to win." LOL.

Earlier this week at the day care center for the youngest granddaughter, Olivia (the middle granddaughter, now a fourth grader) had the opportunity to do this again. This time it was candy corn in a jar. She won the jar, guessing 153 candy corns; the actual number was 150. I was not there to help this time. The winner is shown as the mother (Kiri) -- probably a legal thing in Texas -- minors not allowed to engage in such "gambling" activity, but it was Olivia who guessed the number, or at least that's what I was told. Whatever. Here's the jar:

This also gives me an opportunity to post her state testing results that we just received this past week. She took the test in the spring of 2015, when she was in third grade:

Her parents asked her and her teachers if she should be "telescoped." Students who are particularly good in math, are "telescoped" into a higher grade level. They go to a different classroom or in some cases to a different school to take "higher" math (for example, fifth graders would go across the street to the middle school to take math). Her teacher said that Olivia is "right on target" and should remain in the math class she is already in. Olivia agrees. She had a good rationale for her decision, but I've forgotten what she said. Something to do with soccer. I assume the teacher did not want to lose a "good" student.

I think the one question she missed on the math portion had to do with the rate of speed of a descending submarine as it burns more fuel (becomes lighter) while moving into denser water (required a  bit of calculus). Or just a lucky guess -- it's all bubbles. The sort of bubbles President Obama wants to get rid of.
