Patent ID: 8781746

Claim:
A well control method, comprising: measuring accelerometer data with a tool driver on a drill pipe in a well; measuring pressure data with a pressure tool on the drill pipe; transmitting measured pressure data via drilling mud with a telemetry tool on the drill pipe; and controlling the telemetry tool with the tool driver by— activating the telemetry tool to transmit the pressure data in response to measured accelerometer data caused by drilling mud being pumped into the drill pipe at least at a normal pump rate used during drilling, deactivating the telemetry tool in response to substantial cessation of accelerometer data caused by stopped pumping of drilling mud due to shutting-in of the well after a fluid influx, and reactivating the telemetry tool to transmit measured pressure data in response to measured accelerometer data at least reaching the predetermined threshold caused by drilling mud being pumped at a second pump rate of a well control operation, the second pump rate being used in the well control operation to kill the fluid influx and being slower than the normal pump used during drilling.
