Schlumberger releases new ultra-high-temperature drilling technologies
Schlumberger has launched the TeleScope ICE ultra-high-temperature measurements-while-drilling (MWD) service and PowerDrive ICE ultra-high-temperature rotary steerable system (RSS).
LONDON –Schlumberger has launched the TeleScope ICE ultra-high-temperature measurements-while-drilling (MWD) service and PowerDrive ICE ultra-high-temperature rotary steerable system (RSS). Schlumberger hopes that these new technologies will enable standard drilling operations in reservoirs with extreme temperatures, expanding the applications and the range of the field-proven PowerDrive RSS and Scope measurement services.
“In high-pressure/high-temperature (HP/HT) projects, customers are under intense pressure to manage costs and achieve drilling objectives. This is particularly challenging because HP/HT environments can affect the reliability of conventional downhole equipment,” said Steve Kaufmann, president, Drilling & Measurements, Schlumberger. “Our new drilling services for ultra-high-temperature wells help our customers eliminate runs, drill wells with precision, and mitigate operational risks to make the un-drillable wells possible.”
The PowerDrive ICE RSS is the only commercially available RSS rated to 200°C (392°F). Together with the TeleScope ICE MWD service, these technologies make up the industry’s first 200°C bottomhole assembly, Schlumberger commented. The fully rotating RSS provides precise directional control and automatic steering, resulting in an increased rate of penetration and reduced operational risks in ultra-high-temperature wells.
The TeleScope ICE service transmits survey and formation evaluation data at high speed, enabling real-time well placement and risk mitigation in harsh drilling conditions. Both technologies include integrated ceramic electronics (ICE) and multi-chip modules that are specifically designed and ruggedized for hostile downhole environments.
The technologies have been field tested in the Gulf of Mexico, Mexico, Malaysia, and the Gulf of Thailand.
