LML’E – PL-341 location

The well PL 320 has a SP/induction and dipmeter log. From the dipmeter, structural dips are 110 to the south. The interval of the gamma ray of PL 320/331 that the measured section lies within  has a blocky character suggesting a channelised environment.

Overall the outcrop is made up of alternating oilsands and claystones of varying thickness . The base of the section is made up of alternating claystone and oilsand beds that average 3” thick. It is conformably overlain by an apparently structureless oilsand. The sand is fine to medium grained, subangular, with some mica present. This bed grades in the overlying light grey parallel laminated claystones. The laminations are less than 1 mm thick. Within this interval are a number of thin oilsands up to 1.5” thick but averages .25”Some of these sands are parallel laminated (1mm) to cross bedded with erosional bases . There is also free oil on the laminae

Some of these crossbeds appear to have bi-directional clay drapes suggesting a tidal origin.

The presence of oil-saturated sand within the claystone sequence indicated that over geological time this claystone has allowed vertical migration of hydrocarbons, it might however act as a seal over the productive life of the well. No fractures were observed. The overlying massive oilsand has an erosional contact with the claystone. Which is in turn is also cut into by the overlying claystone/sandstone bed. It grades upward into another structureless oilsand, it is in turn overlain by a loose highly weathered yellow brown oilsand that has no visible sedimentary structures.
