Random Note Regarding A Dry Well In Newporte Oil Field -- December 26, 2017

This well was reported as dry today:

• 33289, dry, Armstrong, Hanson 33-43, Newporte, Cambro/Ordovician, no production data, 

This is from the summary at the file report:

This well was drilled on the outer rim on the west side of a seismically-defined meteor impact crater. Production has been established in two wells; one on the eastern side of the crater, and on the southwestern side of the crater. Both of these wells are completed in the Deadwood Sand.

This well, unfortunately, found no Winnipeg Sand. Just below the Winnipeg Shale is a tight sand identified as Deadwood Sand. There was no show in this sand. The Winnipeg Sand is quite pyritic; it usually appears as medium grained sand with pyrite filling the interstices. [The geologist] referred to the Winnipeg Sand as chrome plated -- that is what it looks like: clear quartz grains protruding through the silvery pyrite. Therefore I believe that the Winnipeg Sand is absent her, and the sand present is Deadwood Sand. 

And then this:

The depths reported by the driller and the logger differ by 56 feet. This could be due to mis-counting drillpipe (2 joints). [The geologist] believes a more likely explanation lies in the abandonment of magnetically marked cables on the wireline truck. This results in depths measured by the logger being less than that reported by the driller. There was fill in the hole; during the latter part of the hole [the geologist] observed black shale cleats up to 1" by 1 1/2'  x 1/2'. The up-hole shales were sloughing in irregular timed pulses. The logger (wisely) did not spud the tool on bottom. [The operator} was in and out of the hole several times whilst waiting for a logging truck to get to location, and [the geologist] cannot image the rig crews mis-counted the drillpipe the same way every time. [The geologist] thinks the presence of ill, and the known error in depth measurements by logging companies since abandonment of marked cables can account for the discrepany in the depths reported by the driller and the logger.
