Description


Drill string telemetry network technology allowing reliable data transmission at speeds up to 57,600 bits per second has been utilized in many land based drilling applications.

The drill string telemetry network incorporates a high-strength data cable that runs the length of each tubular joint. The cable terminates at inductive coils that are installed in the secondary torque shoulder of each connection.  As the drill string is assembled, the inductive coils in adjoining tubulars are brought close together allowing data to flow across the connection.  The network signal is boosted occasionally by repeater subs, which also provide locations for along-string temperature measurements.  The technology offers robust, reliable operation and is virtually transparent to standard rig procedures.

This presentation details the lessons learned and value derived from the use of an ultra-high speed drill string telemetry network and compatible rotary steering, drilling dynamics and advanced formation evaluation measurement tools while drilling multiple laterals of an extended reach horizontal well from a semi-submersible drilling rig.

Of particular focus will be discussion of the specific value gained from:  real-time analysis of high resolution dynamics and inclination measurements to instantly manage the drilling transition between relatively unconsolidated sands with imbedded hard calcite-cemented stringers; instantaneous network-enabled surface control of rotary steerable tools to eliminate non-productive time and improve directional control; real-time transmission and interpretation of high-volume, memory quality formation evaluation measurements to improve geological well placement; and non-productive time elimination resulting from the availability of full telemetry redundancy.
