    摘要: Subterranean oilfield sensor systems and methods are provided. The subterranean oilfield sensor systems and methods facilitate downhole monitoring and high data transmission rates with power provided to at least one downhole device by a light source at the surface. In one embodiment, a system includes uphole light source, a downhole sensor, a photonic power converter at the downhole sensor, an optical fiber extending between the uphole light source and the photonic power converter, and downhole sensor electronics powered by the photonic power converter. The photonic power converter is contained in a high temperature resistant package. For example, the high temperature resistant package and photonic power converter may operate at temperatures of greater than approximately 100° C.

    摘要: Hybrid electrical-optical telemetry systems and methods are disclosed. The methods and systems facilitate faster data transmission rates between the surface and downhole tools and sensors. The methods and systems may also include a downhole electrical bus for inter-tool and intra-tool communication to facilitate limited changes to existing downhole equipment. Some embodiments of the hybrid electrical-optical telemetry system include a light source at the surface and a downhole modulator. Some embodiments also include redundant, selectable optical systems. The methods and systems may operate via a single optical input/output cable.
