This service is enhanced by the application of Silixa’s unique k-w processing which allows intervals of acquired acoustic data to be processed through to fluid speed of sound and flow velocity answers which can give calibrated references for downhole slurry density and hence proppant concentration and also flow rates in a given tubing size.
A further enhancement to the suite of measurements incorporates an iDAS enabled optical surface flow meter placed on the flowline to continuously monitor the rate of fluid being pumped into the well and the proppant/water fractions. This information is then recorded alongside and seamlessly integrated with the downhole acoustic and temperature data.
A comprehensive view of the downhole environment
Silixa can integrate third party data such as depth based petrophysical logs and time based pump pressures into the larger data set so that composite data presentations give the end user a comprehensive view of the downhole environment and stimulation conditions.
With a fibre optic cable in place the sensor array intended for fracture monitoring can then become a versatile monitoring system for the life of the well, allowing for objectives such as cement evaluation, flow-back and production monitoring, seismic surveying and well integrity surveillance to be accessed as required and without further intervention.
