Reservoir Model Types
Abstract
Every reservoir is in some way unique.
There are nevertheless generic issues pertinent to certain reservoir
types and, in terms of model design, these are the issues which inevitably
require attention.
We don't aim to cover all possible reservoir types but we do hope to
indicate trains of thought which we have found fruitful. Along the way, we
can elicit distinctions between models for clastic and carbonate reservoirs
and some courses of action to take if the reservoir turns out to be fractured.
If all reservoirs were just tanks of sand, this task would be trivial. In
practice, geology and fluid dynamics combine in complex and intriguing
but ultimately understandable ways. Adapting a line from Leo Tolstoy's
Anna Karenina:
Homogeneous reservoirs are all alike; every heterogeneous reservoir is hetero-
geneous in its own way.
