Information about microseismic events (events with magnitudes less than zero) can provide valuable insight into what can’t be felt or seen from the surface.

Microseismic data can help operators evaluate the completions of wells that were drilled to produce hydrocarbons from unconventional reservoirs.


Microseismic monitoring data provides the location and magnitude of the event, allows you to interpret fracture direction and dimensions and other source characteristics, as well as the stimulated volume created during operations...leading to better reservoir management and improved reservoir recovery. 

Passive Frac Imaging a cost effective alternative to microseismic monitoring

Interpreting the data is an important part of frac monitoring. A level of uncertainty is inherent, depending on the number of recorded events, their location and the accuracy of the location computation. Uncertainty can be expensive. Typically, microseismic monitoring is done with one or more strings of downhole geophones. Installation can be costly, with no guarantee of quality results. 


In certain areas, microseismicity associated with hydraulic fracturing can be detected and characterized by sparse surface networks of high-quality three-component instruments. 


Passive Frac Imaging (PFI)

Passive frac imaging (PFI) is a scalable, cost-effective approach that is most successful with a sufficient number of stations installed in quiet locations in an optimized network design. With our extensive expertise in data processing, we’re able to get the most from your data, ensuring you get the most for your investment.


Nanometrics uses small networks and advanced signal processing to give you all the data you need to make important operational decisions, at a fraction of the price of going downhole.
