“The ability to now communicate over a drilling motor power section enhances geosteering BHA capabilities and lets you place third-party hardware anywhere on the string,” said Ian Falconer, marketing manager, Drilling & Measurements, Schlumberger. “It is possible to fine-tune the borehole trajectory while drilling ahead at high-speed. This maximizes drilling performance while directly reducing drilling costs.”
An operator in the Middle East drilled a 4,567-ft section in one run with no non-productive time and reduced stick/slip from 100 rpm to 25 rpm. This increased rate of penetration 33% higher than the field average, with the well setting the field record for the longest 8 ½-in. hole drilled in a single run.
This fully rotating powered RSS reduces stick/slip, maximizes torque, weight on bit and penetration rates allowing operators to maximize drilling performance and reduce rig time.
“With Orion II, more quality data and higher resolution images can be transmitted, at greater depths, enabling better drilling decisions to be made in real time,” Mr Falconer said.
The platform combines new data compression technology housed in the MWD/LWD tool with new surface and downhole sensors that modulate and demodulate signals and overcome interference from drilling and rig noise, even in harsh environments. Downlink commands are sent in real time while drilling without affecting delivery of measurement data to surface.
