Abstract

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the downhole assembly in response to the developing well profile (i.e. without first requiring that the assembly be withdrawn and replaced with a solely dedicated treatment assembly).
