Memory-Mode Logging Tool

National Oilwell Varco (NOV) released the BlackBox Eclipse memory-mode logging tool, an extension of the BlackBox memory-mode product line. NOV drilling-optimization tools, including the BlackBox Eclipse tool, can be deployed in multiple locations along the bottomhole assembly and string and in the drill bit. Because of its compact and flexible size, the BlackBox Eclipse tool can be deployed in string or near-bit carrier subs ranging from 4.75 to 9.5 in. in outer diameter. This allows for a thorough analysis of downhole behaviors through multiple placement locations to determine stick/slip, torque and drag, or damaging off-bottom practices. These indicators allow NOV’s optimization engineers to provide mitigation techniques to damaging drilling practices while drilling, leading to lower nonproductive time and reduced well-delivery costs. The combination of these factors allows for a cost-effective method of improving drilling efficiency. The BlackBox Eclipse tool is especially effective in batch-drilling applications or pads with multiple adjacent wells. This allows NOV’s optimization services’ “drilling roadmap” to be applied to multiple wells effectively, maximizing value and increasing performance. This tool has seen early successes in the south Texas Eagle Ford formation and the Oklahoma Woodford formation, where it was deployed with a BlackBox slimhole tool.
