Dah nak habis, finis, tamat, kaput, whatever. InshaAllah lagi 2 hari aku balik. Well ni memang tak ada apa. Shows yang aku nampak dan describe dalam mudlog tu most likely tinggalan sahaja, remnants of oil/gas migration from the source rock to the reservoir. I.e. these sands are mere conduit. The K-5 sand being very good, clean, porous and permeable, the HC went through it cleanly with little residue. The L sand on the other hand are more shaly, less porous and permeable, so that it retains just slightly more of the HC stuff that went through it. That's why the show is twice as good here. The source rock? Probably the L shale, from where the HC primary migration up into K-5 and down into L.
