Each sampling collector includes a sensor and a plurality of random access memory (RAM) pages to store sensor data received from the sensor. When one of the sampling collectors receives the enable signal from the data acquirer, a current RAM page currently receiving sensor data from the sensor continues to receive sensor data without interruption and an immediately preceding RAM page storing a last completed page of received sensor data is transmitted from the one sampling collector to a memory of the data acquirer and from there to a surface computing system. As such, recent data is retrieved and transmitted for processing without interrupting the continuous collection of sensor data.

Abstract: A method for operating a drilling system that has a mud pump disposed on an earth surface and a drill string with a bottom hole assembly (BHA) in a borehole. The method involves turning the mud pump ON or OFF according to a pre-determined sequence so that the mud flow in the borehole fluctuates between high and low. The mud pulser in the bottom hole assembly senses the fluctuation in the mud flow and generates a binary signal accordingly. The mud pulser further sends the binary signal to a measurement-while-drilling (MWD) tool in the bottom hole assembly. The binary signal executes one or more firmware in the MWD tool.
