Angus took many samples during the drilling to use for geochemical analysis.The initial results of this
work show total organic content through the Kimmeridge section between 2-12%, exceeding Horse Hill
in places. Furthermore, evidence shows that the highest organic content corresponds to the limestones
and, in particular, the intervals in between the limestones which have natural fracturing. Whilst organic
content is not the same as oil content, it is indicative of those sections where oil content will be highest.
This supports the potential for some 200m of reservoir of interest. Actual oil content depends on the
extent to which burial has resulted in pressures and temperatures sufficient to generate oil. Initial Tmax
and Hydrogen Index readings correspond with Horse Hill data. Since oil was produced briefly at Horse
Hill and as it is most likely that the oil in the Portland Sandstone in Brockham is sourced from the
Kimmeridge, the evidence backs a similar oil content to Horse Hill.
Therefore, based on the evidence so far, Angus has confidence that the well will be similar to Horse Hill
and perhaps given that the reservoir is potentially much thicker in zones not previously tested the results
could be even better. These results achieve everything short of production to prove the potential from
this zone.
