Log evaluation was\r\nnot practical due to washing out resulting in excessive hole sizes. The Brent\r\nGroup sandstones came in sandstones at 2461 m. There was 160 m net sand with\r\naverage 27% porosity. The sands were oil-filled down to a section of\r\nclaystones, coals and minor sands at 2520 m. An OWC was inferred at 2533 m.
