Abstract:
1. A method comprising: injecting a fluid through casing perforations into an injection zone of a formation penetrated by a wellbore in response to operating a pump in the wellbore; sensing well data comprising injection pressure, injection flow rate, and elapsed injection time, wherein the injection pressure and the injection flow rate are sensed at the casing perforations into the injection zone; receiving the sensed well data at a control device remote from the wellbore and connected to the wellbore by a two-way communication network, the control device being operable with a user interface via the two-way network; determining a formation injection performance parameter in real-time using the received sensed well data, wherein the formation injection performance parameter comprises at least one selected from the group consisting of negative skin, positive skin, and water channeling; and outputting a signal in response to a correlation of a well parameter associated with the formation injection performance parameter and a corresponding preselected threshold well parameter associated with the formation performance parameter.
