The onshore oil industry is a low-key, relatively unobtrusive business that has made strenuous efforts to develop the hydrocarbon assets of this country in an environmentally acceptable manner.
My company participates in production from three fields located in attractive countryside in southern England, where a few carefully landscaped sites drain oil from the surrounding areas by means of directionally drilled wells, extending in some instances for several kilometres beneath the surface. Fields are typically small and profits unspectacular, but onshore production averages some 7 per cent of our national requirement.
Your scare regarding subsidence is unhelpful, since this is a rare phenomenon world-wide and is the result of specific geological circumstances which more that 50 years of onshore production in the UK has clearly demonstrated do not exist here.
