The Schiehallion field has experienced many reservoir management challenges since first production in 1998. Dynamic data such as formation pressures, pressure-transient analysis, interference testing, tracer analysis, and 4D seismic need to be interpreted with great care—Schiehallion has examples in which the data have been invaluable and others in which the data are ambiguous or misleading. It is essential to integrate several data types to obtain reliable conclusions. This paper describes some of the highlights and pitfalls experienced in Schiehallion.
