Successful Exploration of a Large-Scale Sandstone Injection Complex, Block 24/9, Norwegian North Sea

E009 Successful Exploration of a large-scale Sandstone Injection Complex Block 24/9 Norwegian North Sea Summary 1 Exploration well 24/9-7 was drilled by Marathon Oil and its co-venturers on Norwegian licence PL 150 during the first quarter of 2004. The well targeted a series of distinct seismic amplitude anomalies markedly discordant to the general structural trend. These anomalies had been interpreted as a large-scale sandstone injection complex. Seismic modeling indicated that the best explanation for the bright amplitudes observed was that they were generated by oil-filled highly porous intrusive sandstone dykes and sills. The data collected from well 24/9-7 (and three
