Core Highlight Check

Check what our search highlighted in Michigan core photos

You'll see 50 spots that our system marked on core-box photos from three tuning wells (19231, BD-139 and 21064). Each one is outlined in yellow, with a close-up beside it and the feature we think it is.

Answer from the photo first. The geologist's original description for that box appears only after you answer, so it doesn't steer your call. A short note is optional. At the end we'll ask for 5 to 10 searches you'd really run, in your own words.
