The total field water cut (Fw) development is defined as a function of total net production
(Np/N). These values are only valid for the total field and cannot be used to forecast gross
production rates for individual wells. For all models, except the ‘No Water’ option, one has to
enter the abandonment recovery factor and water cut. The various models are:
Stiles
Layered reservoirs with different kh values. If chosen the user is
automatically reminded to fill in the layer data.
Buckley-Leverett
Flooding of a homogenous sand package.
Empirical
The shape can be manipulated to fit observed data. If chosen, the
user has to define the water cut development using three additional
parameters. See the on-line help for a further definition of the
available methods. This model is required if the user wants to match
historical field data that can be loaded (entered) using the
button and matched with the
button.
In this session we will use the Buckley-
Leverett option with the following
parameters:
Hit ‘Apply’ to validate the changes.
It is necessary to enter the relative permeability relationship for Oil-Water. Click on
to
enter the relative permeability dialog, and enter the following data under the ‘Kr Data’ tab:
Press the ‘Kr Two-Phase’ tab to visualize the corresponding relative permeability curves:
