Intelligent well system and method

A system used to monitor an operation in a well, comprising:

• a pump in communication with the well and with a source of material at the surface;
• an intelligent completions device positioned in the well proximal a desired fluid placement position;
• and
• a surface controller in communication with the intelligent completions device adapted to receive data from the intelligent completions device and provide an indication of the placement position of the material.

A method for monitoring an operation in a well, comprising:

• injecting a material into the well;
• monitoring a characteristic in the well by using a sensor positioned in the well, the sensor being a fiber optic line;
• determining the placement position of the material in the well from the monitored characteristic;
• and
• increasing the resolution of the measurement provided by the fiber optic line by routing at least a portion of the fiber optic along a nonlinear path.
