As energy demands increase rapidly, the goal of energy companies is to maximize ultimate recovery in an economically sound manner. One critical capability is the accurate measurement and monitoring of production from individual layers / perforated intervals in a multi-zone completion. This data allows operators to optimize zonal production, improve recovery, increase production per well and reduce overall lifting costs. In spite of its importance, there is limited use of downhole flow metering, particularly in highly deviated and horizontal wells. This stems from the high intervention costs of workover and coil-tubing operations, as well as practical technology limitations, including difficulty in logging highly deviated wells and uncertainties with conventional production logging tools.

Distributed fiber optic sensing technology offers a solution for downhole production monitoring and reservoir monitoring by overcoming the cost and technology challenges encountered with traditional point sensors.   Silixa’s Intelligent Distributed Acoustic Sensor (iDAS) and ULTIMA Distributed Temperature Sensor (DTS) facilitate an unprecedented opportunity for operating companies to obtain permanent, continuous downhole flow metering. By comprehensively understanding the technical and business implications of implementing permanent monitoring using the iDASand ULTIMAD TS, operators can thoroughly evaluate the value added by introducing this new technology to their completions.
