NovoSphere: Sourceless Formation Evaluation for Safer, Efficient Drilling


02/24/2025


We recently unveiled NovoSphere, the industry's first sourceless formation evaluation logging-while-drilling (LWD) service. This groundbreaking innovation delivers precise formation density and porosity measurements during drilling—without relying on a chemical radioactive source.

Key Features
The NovoSphere service is powered by advanced hardware and digital modeling, enabling sourceless density measurement with exceptional precision and accuracy. It functions across a broad range of densities and various lithologies, enhancing formation evaluation capabilities.

Its compact 25-foot collar seamlessly integrates essential petrophysical measurements—including porosity, elemental capture spectroscopy, sigma, array resistivity, and dual ultrasonic caliper—offering a comprehensive near-bit evaluation solution.

When combined with SLB’s high-speed telemetry system, NovoSphere ensures real-time transmission of high-quality formation evaluation data to the surface. This capability supports quick, informed decision-making to optimize well placement and drilling performance.

Why It Matters
Regulations in numerous countries restrict the use of radioactive sources, leading to challenging abandonment procedures and operational risks if a radioactive source becomes stuck or lost. NovoSphere presents a safer, more efficient, and environmentally responsible alternative by delivering accurate density measurements without a radioactive source.

"NovoSphere is transforming the industry," said Cecilia Prieto, Business Line Director for Well Construction Measurements at SLB. "By removing the need for a radioactive source, we offer our customers a solution that enhances safety, improves efficiency, and reduces environmental impact."

A New Era in Formation Evaluation
This revolutionary technology improves operational safety, enhances efficiency, minimizes environmental risks, and enables better decision-making for well placement and drilling optimization.

With its unparalleled capabilities, NovoSphere is set to redefine formation evaluation and well placement strategies within the energy sector.

The service was introduced at the International Petroleum Technology Conference in Kuala Lumpur, Malaysia, marking a significant milestone in the evolution of formation evaluation technology.
