The cebu limestone currently being drilled though low porosity for oil does provide good seal for potential oil trapped below, meaning it cannot escape. In terms of Dennis saying "The Cebu Coal Measures are the primary source of the oil and gas in the region and they underlie the Cebu Limestone." I cannot recall this mentioned previously and certainly should have been in the spudding of the well along with the well schematic ideally. Just thinking for those who called "duster" and sold may have benefited from this intel.
I was happy to pick a few more up at 8c so bring on the Coal measures sandstone.
