Vidar Chalk Mbr (Central Trough to Western Norwegian Danish basin)

Rogaland Group, Sele Formation

MORE WORK BEING DONE ON BIOSTRAT TO DEFINE REWORKED COMPONENTS AND CONFIRM INTRA SELE STRAT POSITION (NOT INTRA LISTA)

Distinct j peak is base Sele (Vidar has reworked Lista and older fossils)

Study fossil data in paly/micropal slides from wells:

1/3-6 2990 - 3010 m

1/3-5 3125 - 3250

1/3-4 2650 - 2740

1/3 - 3 3025 - 3175 3075-3150 = Vidar , no study needed

1/3-1 3075 - 3225

Logs from well 1/3-1 (pdf)
Logs from well 2/1-4 (pdf)

1/3-7 3060 - 3260 has 4 cores in this interval = 74.5 m

7/12-1 2850 - 2870
well 7/11-5 nearby has good data, can likely project strat, no biostrat study needed
