Microseismic Waveform Data

Optical Fiber data quality has come a long way in the last two years. The example above is an image of the horizontal part of two optical fibers that are actively monitoring a third offset well. The microseismic event in the image is of average quality. With high signal to noise ratio for microseismic events as observed by optical fiber, we are detecting on the order of thousands to tens of thousands of events per treatment well in the Permian Basin. 



Crosswell Strain Data

Nanoseis uses automation to pick fracture hits and produce statistical plots during real-time to help you optimize completions as you frac.

Optical Fiber Strain observations are crucial when measuring the response of the reservoir as a result of your frac. By putting a fiber in an offset well, the strain experienced by that offset well shows the complexity and intensity of the fractures produced in addition to the apparent velocity of the fracture propagation. By analyzing these plots, NanoSeis can help you optimize your completion programs.

Optical Fiber Acquisition

Optical Fiber Microseismic Processing is production ready.  We have extensive experience with a variety of acquisition geometries and fiber types. Contact us for an acquisition design consultation free of charge.


High Quality:

With the improved signal quality of optical fiber measurements over the years, microseismic events can be confidently detected and located.


Technique:

Two fibers is better than one. Often the vertical part of the fiber contributes to the event locations providing even more certainty to your velocity model and event locations. 


Low Cost:

The cost of acquisition has dramatically reduced over the years. With affordable multi-fiber acquisition, accurate microseismic event locations can be determined and crosswell strain can be measured from one or more locations in the subsurface.


Results:

Acquiring a fiber microseismic survey produces a microseismic event catalog and a crosswell strain dataset that can be analyzed together to characterize and optimize your completions. Let us share our strain interpretation expertise with you on your next pad. 


Temporary Fiber:

Using a temporary fiber deployment method allows for an inexpensive solution to multi-fiber event locations and cross-well strain measurements. For multi-well completion programs, the fiber can be moved to observe the frac from various locations and depths throughout the completion sequence.  The difference in data quality between a cemented and a temporarily deployed optical fiber is marginal.  


Permanent Fiber:

Cemented fibers come with their own benefits as well. A permanent fiber is required for production monitoring and/or perforation allocation in addition to cross-well monitoring. The difference in data quality between a cemented and a temporarily deployed optical fiber is marginal.

NanoSeis uses a sophisticated compression algorithm to handle large data volumes produced by optical fiber data acquisition. In the example above, the top image shows original, raw, not-compressed data file containing a microseismic event acquired by optical fiber. The bottom image shows the same microseismic event from a compressed data file using an extreme compression ratio of 105:1. The aggressive compression ratio of 105:1 shows no loss in data quality. In practice, we use a much more conservative compression ratio, although the compression ratio can be increased at any time.
