A set of mathematical models relating surface production rate history of one well to the its bottomhole pressure history and offset injection raterates history.
In case the bottom-hole pressure data is not available it is considered constant over time.
...
The major assumptions in CRM model are:
- productivity index of of producers stays constant in time
- drainage volume of producers-injectors system is finite and constant in time
- total formation-fluid compressibility stays constant in time
