Real-time formation evaluation without radioactive sources

NovoSphere™ sourceless formation evaluation logging-while-drilling service provides exceptional environmental benefits and operational efficiencies. By using pulsed neutron generator (PNG) technology, it eliminates the need for hazardous radioactive sources, making NovoSphere service a sustainable option for thorough formation evaluation. This innovative tool from SLB reduces carbon emissions while improving accuracy, range, and performance across diverse lithologies and formations. NovoSphere service provides a spectrum of critical measurements including sourceless neutron-gamma density, sourceless neutron porosity, elemental spectroscopy and sigma, array resistivity, ultrasonic caliper and images, as well as annulus pressure and temperature while drilling for comprehensive formation evaluation in real time.

• Conventional and unconventional reservoirs
• Environmentally-sensitive drilling  
• Long horizontal wells
• Well abandonment and sidetracking

• Provides improved accuracy and extended measurement ranges of sourceless density measurements across a variety of lithologies including complex carbonate, sandstone, and shales
• Reduces regulatory complexities during fishing, sidetracking, or abandonment procedures
• Simplifies operations by eliminating the need for certified logistics to handle radioactive sources
• Minimizes rathole drilling and reduces rig time with a compact design that integrates multiple measurement functions within a single collar
• Provides high-quality formation evaluation data in real time, enabling operators to make rapid and informed decisions to optimize well placement and improve drilling efficiency
