Wired piped application for deepwater

HOUSTON -- The use of the combination of a high-speed telemetry drill string and downhole measurement or rotary steerable tools is often referred to as an intelligent drill string, said Maximo Hernandez with IntelliServ at the 2008 DOT conference in Houston. The ability to transmit data at high rates allows to instantaneously eliminate rig downtime related to data or commands transmission from and to surface, he added.

Hernandez explains that drilling risk is reduced as all formation and drilling dynamics data is fully available at surface as well as a redundant telemetry system. He continued to explained that special applications otherwise not capable without drillpipe telemetry can be enabled such as geosteering under total fluid losses or real time, closed loop bottom hole pressure control to name a few.

Hernandez says the oil and gas community is well aware of the need for abundant, accurate, and timely information at a transfer rate of information at 57,000 bits per second compared with perhaps 30 bps for information transmitted through a mud column.
