Fracture monitoring

Completion and fracture operations in unconventional wells can comprise 50% or more of the total well cost.

Silixa’s ArrayFrac™ fracture monitoring services maximise well productivity by delivering actionable insight into the wellbore and reservoir.

Understanding the effectiveness of the fracture completion is a critical piece to optimise well cost and improve overall recovery. The application of distributed fibre optic measurements is now allowing operators to have a better understanding of the different completion designs and how they can optimise those designs for specific formations and areas.

Improving recovery by offering a complete picture of the well

Understanding the effectiveness of fracturing is key to improve the economic performance of unconventional wells.

With Silixa’s fracture monitoring service acoustic and temperature data is acquired continuously giving the user a complete picture of where fluid and proppant are going in the well. Individual perforation clusters show up as active or inactive and more detailed analysis of the data indicates the relative amount of slurry that is taken by each cluster in a stage giving a unique insight into the effectiveness of the fracturing process.

Continuous stream of data with no interruption to operations delivers significant cost savings

Actionable information can be acquired even from the treated well.

Real-time or near real-time answers from the entire wellbore for confident, on-the-fly decision making

Silixa’s fracture monitoring package includes a mixture of real-time visualisation, near-real-time processing and display and post survey analysis designed to give the stimulation engineer the tools to make confident on-the-fly decisions.

  • Actionable information from the treated well
  • Realtime and near-realtime answers about fluid and proppant placement
  • Quickly identify of completion leaks and undesirable fluid communication
  • Decide when to use diversion and then monitor effectiveness
  • Make informed adjustments to subsequent stages to better exploit the shale
  • Revisit future well placement and spacing based on real well information

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.

One fibre, multiple applications for the life of the well

The optical fibres provide an in-situ sensor array that makes it possible to acquire temperature and true acoustic information at every point along the cable path.

Although intended for fracture monitoring, our fiber optic solution can 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.


Our remote operation capabilities not only increase efficiency, but significantly improve safety as well as our hydraulic fracture monitoring service requires minimal on-site time. This delivers obvious HSE advantages.


Hydraulic Fracture Monitoring with Silixa’s real-time display and analysis capabilities customers can optimise pump schedule and treatment designs to help reduce completions time and reduce casing and plug failures that result in expensive recovery and repair operations.

Environmental footprint

With Silixa’s remote monitoring capabilities we can reduce, and even eliminate in in some cases, the need for field engineers to travel to the wellsite to perform frac monitoring services helping to reduce the carbon footprint.

Typically, the optical fibre cable will be placed on the outside of the production casing on a plug and perforate completion which requires a specific installation technique and oriented perforation solution (cable mapping) to ensure the cable is preserved throughout the completion phase and beyond.

Once the fibre is in place it can be used for multiple applications throughout the live of the well.
