Thanks for that @exmann

Good answer.

So after after they drill the initial wells on Rangers/ Flames, they only have the small vertical well Thelma lease in Murray County in the Orion JV with SHE which may give them 1-2 MMBO reserves shared 50/50 .

There is another ~3 MMBOE of reserves they could access via the STACK portfolio, but they are small, non operated interests where BRK have no control over the development schedule and timing.

The 20% WI in the Bullard DSU is a potential expansion play, but they would need to buy the majority land position from Rimrock, the operator.
