Our breakthrough Acoustic Imaging® is a differentiated technology that offers  high resolution, real-time images of fluid fractures. Armed with dynamic fluid images, clients can make quick and informed decision on completion design, well spacing, and parent-child well interaction in the reservoir.

  • Data can be ACQUIRED with conventional, wireline conveyed geophones, wireline conveyed Distributed Acoustic Sensing (DAS), or permanent DAS

  • Acoustic Imaging®can be applied to any existing downhole or DAS dataset.

FRACTURE IMAGING INTEGRATION

 

Flexible, cost-effective and reliable wireline data acquisition services are available to customers in North America. Our Health and Safety program is qualified with multiple super-majors.

We can acquire high fidelity wireline distributed fiber data in combination with geophones, or wireline distributed fiber can be run into a well without geophones.

APPLICATIONS

TECHNOLOGY

 

Acoustic Imaging®, also called “microseismic imaging”, “fracture imaging”, or “microseismic reflection imaging” is the technique that utilizes the acoustic energy released during stimulation when rock breaks to directly image:

  • Natural fractures

  • Fluid filled induced hydraulic fractures

  • Fluid and proppant filled fractures 

  • Lithology

slide15_edited.jpg

This technique was developed by Anton Reshetnikov. He obtained his Ph.D (THESIS) in 2014 from Freie Universität Berlin under Dr. Serge Shapiro on this subject and to date has dedicated over 15 years of his career to the research, development, and commercialization of this technology. Downhole microseismic data have almost an order of magnitude higher frequency content than seismic refection data obtained at the surface; therefore, a comparable increase in image resolution is both expected and has been successfully demonstrated to 1.5meters, or 5 feet in each of the North American Basins.

Premise: As fluids and proppant are pumped and generate fractures, it alters the acoustic rock properties

Much like an acoustic image log scans for natural fractures, we transform the Microseismic events into acoustic sources

slide16_edited.jpg
  • As fluid and proppant are pumped into the reservoir, a hydraulic fracture is created

  • This physical response is a tensile, opening motion

  • Acoustic Imaging provides the 3D orientation of the tensile hydraulic fracture which is filled with fluid and proppant

The native output from the imaging workflow is 5 ft (1.5m) resolution seismic reflectivity volume in depth. The following examples represent the transformation from 1) Microseismic event locations; 2) To a reflectivity volume ;

3) To extracted natural and induced hydraulic fracture features; and 4) To planar fractures which were loaded into Petrel
