SLB launches Retina at-bit imaging tool

HOUSTON, May 20, 2025 – SLB has launched Retina, a new at-bit imaging technology that delivers high-resolution borehole images from the first point of drill bit contact, enabling better formation evaluation and drilling decisions, the company said Tuesday.

The Retina tool marks a major advancement in borehole imaging by capturing precise visual data in sections previously inaccessible due to drilling fluid or structural limits.

It is especially effective in large-diameter boreholes and helps identify formation characteristics at the earliest stage of drilling.

The solution enhances geological characterisation and detects early risks such as mud-loss zones, hard drilling intervals and stuck-pipe events.

“Retina provides an unparalleled view of the formation and its characteristics downhole, enabling better-informed decisions from the start,” SLB well construction president Cecilia Prieto said.

“This leading-edge technology marks a significant advancement in borehole imaging, providing drillers with critical insight in situations where it was previously impossible.

“With imaging at the bit, before the formation is affected by drilling fluids, the exceptional resolution unlocks new opportunities around drilling, fluid management and completions, leading to significant risk reduction and production optimisation.”

Field tests in South America and the Middle East showed Retina’s performance across different environments.

In South America, the technology identified conglomerates early in the cycle, helping to select more durable drill bits and reduce downtime.

In the Middle East, it detected fractures and vugs in carbonate formations, improving planning to prevent mud losses.

The tool also imaged stylolites, which act as pressure barriers, helping to map productive zones.

SLB is a global energy technology company with operations in more than 120 countries.

It offers drilling, reservoir evaluation, production, processing and digital services for upstream and midstream oil and gas operations.
