Case File Template and Usage
Here are several examples and templates on start using ICV Control. The use
of ICV Control usually requires heavy load of trial and error to test out several
options.
ICV Control is set to be a continuously evaluating the parameter until it fulfills
the target. Here are two examples of a "static" target. The parameter surpasses
the target at certain period, triggering the ICV Control to search on an ICV
position that fulfills the target, eventually closing it. While setting the
target slightly higher, will result in closing the ICV in later period of time.
This requires changes of target for every time period, which is not robust.
An example is made using a dynamic target, where we set the parameter to be
normalized with certain constant. Creating a continuous function that evolves
over time, to be set as a target. The result shows that ICV Control can follow
the evolution of the parameter, which requires more choking towards the end.
This dynamic target is what we suggested for the users to use, therefore in previous
example of Keywords, there are many parameters that is divided into different
parameters to trigger the normalization.
Zonal control on single well and branch control for multi-lateral for water-cut
This is an example of mixes of zonal control and branch control in one ICV Control case. The zonal control is installed for single well completion, while the multi-lateral will have the branch control.
