Pressure in the simulation model

[Shakespear]

could you please advise me how can I put history reservoir pressure in the model,*.data file,what keyword used to do that and if it is under SHECUAL section.
Thank you in advance for any reply

Take a look at the EVENT File in SCHEDULE. That will help you. Take a look at the tutorials to see in detail how this is done.

Also look at keyword WTEST in ECLIPSE as this would be equivalent (assumptions) to doing a welltest on the well during your simulation at a specific point in time.
