Coherency Processing
The CohTEEC Technology

The  CohTEEC  approach consists of a number of methods and algorithms suitable for mapping lithology  changes, gas (oil) - water contacts and fracture delineation. 
Multi-trace filters are means to detect and map faults and fracture  zones. Also lithology changes and  gas (oil) - water contacts lead to a different   seismic wave picture characterisable with CohTEEC attributes. Pattern recognition and  feature extraction are further methods to generate seismic attributes and to cope with the  amount of data  contained in 3D seismic surveys. Such filters and algorithms are widely  known from material science and medical image processing.  

A variety of  different algorithms leading to 2D and 3D Volume Attributes  are possible that can be used to characterise the seismic signal. Advantages of using  CohTEEC attributes are : 

  • Through a variety of available algorithms and operators a bundle of  solution-dependent methods can be implemented 
  • Only a short time window is necessary for most of the attributes 
  • The local orientation of geological features can be taken into  account.  

The underlying software is developed inhouse and subject to a  continuous development. The proprietary code and the algorithms do not touch  existing  patents. 

The following examples for CohTEEC   attributes are availible. 
 To simultaniously view dip, azimuth and attribute value the
IHS-Display technique is  a valuable aid.
