The Capacitance-Resistance Model (CRM) is a class of mathematical models relating the production rate history to the offset injection rate history with ability to account for the producers bottom-hole pressure variation.

In case he case the bottom-hole pressure data is not available it is considered constant over time.

...

It only provides hints for misperforming wells and sectors which need a further focus.

...

CRM trains linear correlation between variation of production rates against variation of injection rates with account of bottom-hole pressure history in producers.

is built around production data against material balance and require current FDP volumetrics, PVT and SCAL models.
