Abstract

As the oil and gas industry advances the exploitation of unconventional reservoirs, onshore ultra-deep formations exceeding 10 000 m in depth and deepwater blocks with water depths greater than 1500 m, downhole operating conditions grow increasingly harsh, with a maximum temperature of 210 °C, peak pressure of 175 MPa, confined borehole spaces and highly corrosive formation fluids. Conventional technologies are increasingly challenged in operating reliably under these extreme downhole conditions. In this context, downhole embodied intelligent agents (DEIAs) constitute a core technical pathway to overcome the aforementioned engineering bottlenecks. This work defines DEIA as an integrated downhole system governed by a closed-loop perception–decision–actuation mechanism, which boasts autonomous decision-making, dynamic environmental adaptability, and multi-agent collaborative operation capabilities. We systematically identify three core challenges arising from practical engineering applications: extreme physical constraints inherent to downhole boreholes, barriers to full-range and high-precision environmental perception, and a severe shortage of robust trainable datasets paired with high-fidelity simulation platforms. Accordingly, we elaborate on three pivotal scientific and technical bottlenecks requiring targeted breakthroughs: the development of intelligent-agent hardware capable of reliable operation under extreme subsurface conditions; reliable kinematic and control algorithms amid coupled multi-physics interference; and sustained long-term operational stability enabled by advanced self-repair material systems. To reconcile the aforementioned technical hurdles with on-site engineering demands, this study establishes a five-dimensional technical development framework customized for major field scenarios, covering layered water injection, complex-condition oil production, hydraulic fracturing, well intervention operations, and durability improvement of DEIAs. This perspective presents a clear development roadmap for the research and field application of DEIAs under extreme energy extraction conditions.
