The Global energy technology company SLb has launched Retina™ at-bit imaging, which enables identification of rocks formation characteristics to optimize drilling efficiency, formation evaluation, and safety. This solution is the  first-of-its-kind and provides accurate measurements, especially at the critical point of first contact between the drill bit and the formation.

“Retina provides an unparalleled view of the formation and its characteristics downhole, enabling better-informed decisions from the start,” said Cecilia Prieto, President of Well Construction, SLB. “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 optimization.”

Retina addresses the limitations of traditional imagers, which are often restricted by operational factors like drilling fluid type and wellbore damage, and often not usable in the reservoir access intervals due to borehole size limitations. 

It is applicable to drilling operations utilizing any drilling fluid composition. Retina also enables the highest-resolution imaging to date,  providing critical insights into the formation. 

Field test data from land operations in South America and the Middle East have demonstrated Retina’s versatility and effectiveness. In the Middle East, Retina revealed the presence of fractures and vugs (small cavities or pores within the rock) in carbonate formations, providing critical information for predicting and preventing mud losses. 

SLB is a leading technology company that drives energy innovation for a balanced planet. It operates in more than 100 countries.
