..., a model reservoir is constructed with heavy oil to be recovered by steam injection. Mapping of temperature propagation within the model reservoir clearly demonstrates fast steam/ temperature propagation to the overburden and then propagate horizontally at the top of reservoir. Hence, top of the reservoir...

...Field Compaction and Subsidence Behavior Initial Stress Field The total vertical stress S V used for the geomechanical model is based on integrated density log data from the area. A composite log is used, with the overburden and reservoir sections from F23 wells, and the underburden...

... data can be converted to other water depths (serve as prognosis for new wells), based on rig floor elevation, water depth, differences in overburden stresses, and on mud properties. Several field cases will be presented with water depths ranging from 380 m to 1350 m, demonstrating the wide...

... not allow for the filling up of a depleted reservoir, and a new discovery therefore had to be used. The most suitable undepleted field, the Grijpskerk field, had a number of very significant uncertainties, including: Complex overburden; evidence of compartmentalisation; diagenetic impairment; and the need...
