This page is part of a category of pages providing a summary of the geology of the Andover district (British Geological Survey Sheet 283), which extends over approximately 600 km2 of north-west Hampshire and a small part of eastern Wiltshire.

Geological description


There are six deep hydrocarbons boreholes, within or adjacent to the Andover district, which provide evidence of the strata encountered at depth. Figure 3 shows the location of the boreholes and Figure 4 details the stratal thicknesses within each. Seismic sections show that Ordovician to Carboniferous strata form the basement beneath the area.

Figure 3 Location of key deep hydrocarbons boreholes in the Andover district and adjacent areas. P807821.

Additional data in nearby deep wells such as Farley South, Stockbridge, Lockerly and Humbly Grove can be found in Hopson et al. (2007), Booth (2002) and Farrant (2002).
