...B. Reinholdtsen Abstract The Draugen Field is an elongate, low relief, anticline containing mainly multi-Darcy sandstones. Oil initially in-place (STOOIP) is 182 x 10 6 Sm 3 . The 1987 Plan for Development and Operation (PDO) assumed a central cluster of 6 deviated production wells and 3 subsea...

... ABSTRACT The Draugen oil field lies in block 6407/9 in the Haltenbanken oil and gas province. The field is located 150 km off the coast of Norway and 200 km south of the Arctic Circle, in water depths of 240 to 280 m. The Draugen field was discovered in 1984 by well 6407/9-1. Five additional...

Map over the Draugen Field of the change in equivalent hydrocarbon column as calculated by the reservoir simulator. Color scale runs 0–5 m. Faults (black) and the extent of the OOWC (red) are indicated. (a) Communication in the north. The large water influx expected in the north is not confirmed by TL3D, so this model is ruled out. (b) Communication through faults. Water encroachment immediately south of the platform is not seen by TL3D, so this model is also ruled out. (c) Communication in the west. This model best matches the TL3D results so it was used as a starting point for seismic matching. (d) Actual observation from TL3D. (e) Final model matched to seismic and production history. The red dot represents the originally planned location of the new well, the green dot the revised location.

In Shell's Draugen Field, the water flood map derived from the first 4D survey in 1998 differed markedly from the simulation maps. After matching the model to 4D data and changing the location of a new production well, the 4D data...

... Abstract Before we get into details and think how to improve 4D monitoring, let us look at some results of 4D surveys in action and get a feel for what they can do for us. Draugen — A Waterflooding Oil Field Our first example is a good example of how we would like 4D projects to go...

For some fields or segments within a field, both fluid and pressure changes have approximately the same degree of impact on the seismic data. In such cases the use of time-lapse...
