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:
A fiber optic based logging assembly deliverable via coiled tubing. The downhole portion of the assembly is directed to develop a logging profile of a well by way of the fiber optic line. Thus, a downhole battery may be provided with the tool. Further, opto-electric interfaces may be provided with the assembly to convert between electrical and optical communication signals. Additionally, with the reduced profile of an optical communication line through the coiled tubing portion of the assembly, an operator may elect to perform treatment applications in real-time. That is, in certain circumstances, the operator may direct a treatment application utilizing the downhole assembly in response to the developing well profile (i.e. without first requiring that the assembly be withdrawn and replaced with a solely dedicated treatment assembly).
