Ann: Merlin-1 Testing Program Update, page-12

The important bits are in the details section, and the numbers within.
48 sidewall cores have been cut in the Merlin well
18 were specifically chosen to have trims taken and analysed, presumably the best of them
5 were from untested zones where hydrocarbons had been observed during drilling
2 confirming the presence of hydrocarbons. which inverts to 3 samples had no hydrocarbons.
13 samples to come, hopefully a better ratio of success in them

It is a concern that the data released so far does not cover gross to net pay. A few feet of productive sands within a play, will not be commercial. The sooner this comes out the better, as for now it is looking distinctly mediocre.
