Cenozoic micropaleontological biostratigraphy of the LASMO/NSR(V)L Cohasset Producer CP1 P-51 well, Scotian Shelf

Cuttings samples from the Cenozoic section of the well LASMO/NSR(V)L Cohasset Producer CP1 P-Sl (Cohasset field, Scotian Shelf) have been analyzed for microfossil content These closely spaced samples contain assemblages of fora-minifera and other microfossils of Paleocene to early Middle Miocene age...
