It's a bad valuation because it compares the two companies on the Laurel only, forgetting that Buru has a ton of conventional oil exposure, has an unconventional oil farm in etc etc It also forgets that Buru's Laurel has actually been proved up with drills while OBL's hasn't and should have a higher risk premium attached to it, and again it includes the less economic 5000m resource and tries to compare it to the 4000m resource.
The problem with valuations is garbage in, garbage out, not that logic and truth has ever worried many posters here.
