1. Reservoir characterisation
Reservoir characterization is concerned with
building an understanding of the subsurface,
with the focus on those regions where
hydrocarbons are present. It covers not only
the rock structures but also the fluids present in
them and their distribution and composition.
An understanding of the changes occuring
over time within the reservoir, as the
hydrocarbons and associated liquids are
released, is also of the utmost value. Reservoir
characterisation is fundamental to all aspects
of exploration and production. It determines
whether or not a prospect is commercial,
it drives the drilling programme and sets
the production strategy, something that
will invariably change as knowledge and
understanding of the reservoir increases.
Seismic surveying, well logging and
monitoring, core and fluid analysis, and, of
course, reservoir modelling all have a role
to play in helping to understand the reservoir
and make the best business and operational
decisions throughout the life of the field.
Characterising Kazakhstan’s complex
reservoirs with their generally high levels of
heterogeneity is not straightforward. However,
it is vital to working out how to maximise
production, often involving improved and
enhanced oil production techniques – IOR
(waterflooding) and EOR.
