This paper describes the techniques applied and the results achieved in matching the six years of production and pressure history of the Piper field. Although Piper is an excellent oilfield it is nevertheless a difficult one to model using numerical simulation techniques. There are complex fluid-flow patterns across non-sealing faults between the offset sand sequences, together with a variable degree of vertical communication across the main reservoir unit. With six years of field data to match, the task was a large one and the question is raised – that, even though a satisfactory history-match was achieved, to what extent can it be regarded as unique?
