	MAW: WellCad interpretation of stratigraphy and facies in c. 130 borehole geophysical logs. Initial phase of log interpretation aimed at building a robust model framework using logs with large vertical coverage (c. +100 m) in the Chalk, providing approximate coverage of one borehole log every 20 km2 across the Chalk south of The Wash. SOBI borehole well path, stratigraphy and marker-bed data written to Excel pro-formas. Lithofacies data compiled into WellCad files exported to text and Excel files, using IF factors to translate lithofacies data into a numerical code appropriate for modelling.

	MAW: WellCad interpretation of stratigraphy and facies in c. 175 borehole geophysical logs. These logs infill areas between boreholes interpreted in Year 1, and include logs that form the basis of previous project work on the Chalk, including London, Berkshire Downs, East Kent, North Kent, East Anglia (Thetford, Saffron Walden), Hertford, Beaconsfield, Salisbury, Marlborough. Other logs include a suite of hydrocarbons boreholes that form a component of a separate BGS project using geophysics to investigate the primary porosity of the Chalk. Lithofacies data compiled into WellCad files exported to text and Excel files, using IF factors to translate lithofacies data into a numerical code appropriate for modelling.
