IV-2 VELOCITY ANOMALIES AND DEPTH CONVERSION – DRILLING SUCCESS ON NELSON FIELD CENTRAL NORTH SEA T. ARMSTRONG Summary 1 The Nelson Field overburden appears to be ‘simple’ comprising smooth horizontal or gently-dipping layers overlying a low-relief Top Reservoir structure. In fact a number of velocity anomalies of Quaternary Mio-Pliocene and Lower Eocene age introduce significant complexity via both steep and gradual lateral velocity gradients which need to be constrained for reliable depth conversion. Introduction The Nelson Field lies about 2.5 km SE of the giant Forties Field along the Forties-Montrose Ridge in the central North Sea. Oil is produced from
