Gain insight into stimulation effectiveness and zonal isolation
Ineffective or improperly designed completions can impact your bottom line. OptaSense DAS technology provides key insights that allow you to optimize fracture program designs and mitigate operational issues while completing the well. Rest assured the stimulation services you are paying for are delivering the results you expect.
When DAS is recorded in a treatment well, it can be used to determine which stages and perforations take fluid and proppant—providing insights into stimulation effectiveness, as well as revealing ineffective zonal isolation.
The OptaSense hydraulic fracture profiling service continuously monitors and records the acoustic signals measured by DAS, temperatures measured by distributed temperature sensing (DTS) systems, and pump data provided by the pumping contractor on site.
With the unique ability to acoustically monitor the injection directly at the treatment zone, our hydraulic fracture profiling service estimates the fluid and proppant uptake at each perforation cluster, which can be used to optimize overall completions and fracture design.
In the field, all phases of the hydraulic fracturing operation can be monitored in real time, enabling you to assess the success of fracture initiation and growth, identify perforation breakdowns, and see stage bypass events as they occur.
Real-time monitoring of hydraulic fracture treatment operations include running and shot characterization of perforation guns, deployment of diversion and sleeve balls, placement of plugs, and operation of tooling on coiled tubing. Monitoring treatment operations in real time enables operators to assess the treatments’ effectiveness and make changes on the fly to assure that they are achieving the best results for the investment made. This ensures quality control over operations to confirm depths and performance of downhole equipment.
Field reports that provide estimates of the fluid and proppant uptake at each of the perforations are generated after each stage and at the end of the fracture treatment. Processed data from the job can be used in post-job hydraulic fracturing diagnostics, as well as to compare hydraulic fracture effectiveness with production logs—which is valuable input for future hydraulic fracture modeling and design.
