A type curve is a graphical representation of a particular,
highly idealised, theoretical, mathematical model of the
pressure response of the well-reservoir configuration during
a welltest procedure. Type curves are derived from
solutions to the flow equations under specific initial and
boundary conditions. For the sake of generality, type curves
are usually presented in dimensionless terms

5. Production Performance Forecasting
6. Pseudo functions
7. Enhanced oil recovery
The material balance equations can be derived by equating
masses of reservoir fluids that exist in and out of the
reservoir with respect to time during the producing life of a
hydrocarbon reservoir. Material balance can be performed
very easily by analyzing the pressure drop in the reservoir as
a result of fluid withdrawal from the reservoir.

7. Enhanced oil recovery
In certain geological settings aquifers have been found that
are so large compared to the reservoirs they adjoin as to
appear infinite. This chapter will focus on reservoirs that are
in communication with large active aquifers, and will
quantify the effect this communication has on the reservoir
performance.

In any scientific or engineering application of analytical
methods, the approach is generally to set up the basic
theory of the subject, and its mathematical description in
one dimension. Such a description is provided through the
displacement theory of Buckley and Leverett. So, this
chapter describes analytical methods of calculating
recovery for an immiscible displacement process in porous
media.

7. Enhanced oil recovery
Reservoir production performance analysis and forecasting
are fundamental responsibilities of the reservoir engineer
and lie at the heart of reserves determination. Several
techniques have been developed for the purpose of
production forecasting, ranging from simple curve fitting of
production data to the rigorous physical modelling of the
drive mechanisms over time (Decline Curve Analysis).

7. Enhanced oil recovery
Immiscible displacement, most notably water displacing oil,
is a key physical phenomenon in many reservoir
developments. A thorough understanding of this topic is
essential for all reservoir engineers (Chapter3, 1D). This
chapter will now address the complexities of immiscible
fluid displacement on a reservoir scale and present
extensions of the analytical methods already developed.

7. Enhanced oil recovery
Enhanced recovery refers to any of a variety of techniques
whereby energy is added to the reservoir in order to
increase the amount of oil and gas that can be economically
recovered from the reservoir. It is also called tertiary
recovery because it comes after natural and secondary
recoveries in the production order.
