Wessex Mining owns a site in Dorset on which there is an oil well. The business does not pump oil any longer because the price of oil is such that it is not economic to do so.

Furthermore, projections for oil prices are such that it may never be worthwhile to exploit the well. Recently, a property developer has offered £500 000 for the site, which it has plans to develop for domestic housing.

What should Wessex Mining do?
