Abstract
A tool driver activates a telemetry tool when a predetermined threshold of accelerometer data measured by an accelerometer. The threshold preferably corresponds to an acceleration level expected while drilling mud is pumped at a slow pump rate through the well's drill pipe. When a fluid influx occurs during drilling, the well is shut-in, and the tool driver turns off the telemetry tool. The drill pipe and casing pressures of the shut-in well are obtained. Then, drilling mud having a first weight is pumped at a slow mud pump rate. Because the tool driver is set to activate the telemetry tool in response to accelerometer data at the slow pump rate, the telemetry tool begins sending downhole pressure data to the surface. In this way, rig operations can change the mud weight and adjust the choke line during the kill operation based on an analysis of the downhole pressure data obtained.
