The appraisal of the Crogga Field will follow a routine industry programme of acquiring new seismic data, process and interpreting that seismic data, planning an appraisal well programme and drilling and testing those appraisal wells. The general procedure is that which has been followed since offshore oil and gas exploration started in the UK in the 1960s. Technology and timeframes have changed since the 1960s but the outlined programme is routine. All of the UKs offshore oil and gas fields are of this conventional type.
