While our speciality as a company is the application of structural geology to exploration and production problems we have many man-years of experience interpreting 2D and 3D seismic data. Over the years our clients have frequently called upon our expertise in seismic interpretation and structural geology to interpret structurally-complex data sets for which they do not have the in-house expertise.
Our experience as seismic interpreters means that not only can we prepare data to our clients' specification, we can also prepare data for input to our in-house developed software for further structural analysis.
Interpretation QC and Fault Analysis:
Interpreting faults has always been a challenge even with the advent of new geophysical attributes and displays (e.g. coherency cubes, volume picking). This is even more so today when interpretations are made in a 3D world where fault are captured as surfaces not just polygons on maps or lines on sections. Fault interpretation is often seriously hindered by data quality. In turn, fault correlation and fault relationships can be ambiguous and fault-surface extent uncertain. These difficulties are often needlessly worsened by untidy interpretation and inappropriate use of auto-tracking tools.
Fault Interpretation Issues
The accuracy of mapping in faulted areas is critical for the correct definition of fields and prospects. Assessment of the 3-dimensional geometry of the fault network, and visualization of the displacement variation on fault surfaces, are important methods for evaluating sub-surface interpretations. Using our TrapTester T7 system we have pioneered new methods for detailed fault analysis, using concepts researched and developed by our colleagues in the Fault Analysis Group at University College Dublin
Using TrapTester T7 we can:
