SLB推出了Retina钻头成像系统，该系统能够早期识别地层特征，从而优化钻井效率、地层评估和安全性。Retina可在钻头与地层首次接触时提供精确的测量数据，随着钻井开始，随着井眼直径向储层段逐渐减小，即使在大孔径范围内也能提供清晰的图像。

Retina 突破了传统成像仪的局限性。传统成像仪通常受钻井液类型、井筒损坏等作业因素限制，并且由于井眼尺寸限制，通常无法在储层通道段使用。Retina 适用于使用任何钻井液成分的钻井作业，能够实现高分辨率成像，从而提供对地层的早期洞察。

高分辨率图像对于钻井一开始的地质表征非常重要，它可以揭示与钻井相关的潜在支出，例如泥浆流失区、钻井困难间隔和卡钻事件，这些支出可能会增加完井时间、产生非生产时间并增加安全风险。

在南美的现场测试中，该技术在钻井周期的早期就识别出了砾岩，从而有助于设计更耐用的钻头，减少停机时间。在中东，Retina 揭示了碳酸盐岩地层中的裂缝和孔洞，为预测和防止泥浆漏失提供了关键信息。在中东的另一场现场测试中，该工具还提供了作为压力屏障的缝合线的高分辨率图像，从而更好地了解产层。

SLB launched Retina at-bit imaging, which enables early identification of formation characteristics to optimize drilling efficiency, formation evaluation and safety. Retina provides precise measurements at the point of first contact between the drill bit and the formation, providing image clarity in large hole sizes as drilling commences and the borehole diameter reduces progressively toward the reservoir section.

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. Applicable to drilling operations using any drilling fluid composition, Retina enables high-resolution imaging, providing early insights into the formation.

High-resolution images are important for geological characterization from the outset of drilling, revealing potential well-related expenditures such as mud-loss zones, hard drilling intervals and stuck-pipe events, which can add days to complete the well, incur non-productive time and increase safety risks.

In South America field tests, the technology identified conglomerates early in the drilling cycle, enabling the design of more durable drill bits to reduce downtime. In the Middle East, Retina revealed the presence of fractures and vugs in carbonate formations, providing critical information for predicting and preventing mud losses. During another field test in the Middle East, the tool also provided high-resolution images of stylolites that act as pressure barriers, allowing for a better understanding of productive zones.
