Improving well control via drilling margin identification, influx analysis and direct measurement

While downhole data are presently available from tools near the bit, available data rates are sparse. The wireless telemetry bandwidth is limited, and wellbore measurements have to compete with the transmission of other subsurface data. However, a high-bandwidth, downhole data transmission system, such as a wired or networked drillstring system, has the unique ability to acquire real-time pressure measurement, at a number of locations along the drillstring.
