Sedimentology

We provide core, thin section, chip sample and SEM analysis that will improve the quality of prior sedimentological, petrophysical, and related structural interpretations.
Diversely applied sedimentology is one of the primary methods that can be used to create more accurate and expansive paleoenvironmental interpretations. Also by applying in depth sedimentological methods the extent of unconformities can be more accurately assessed. This will greatly contribute to the accuracy of sequence stratigraphic interpretations and/or an individual’s understanding of the depositional history.
Core, chip sample, thin section and SEM are used interactively to attach sedimentological data to logs and seismic. Small-scale sedimentology can provide the information required to more completely understand the diagenetic history, porosity, permeability and pore structure allowing for a more accurate and complete characterization of the reservoir.
Sedimentology involves dealing with different scales of data and therefore data scaling. Connecting different scales of data is incredibly important especially for determining probable vertical and horizontal anisotropy in the reservoir. The largest problem is the inherent error involved in upscaling data several times in order to reach the reservoir scale. Through accurate and expansive data collection we provide data that is as seamless as possible effectively preventing as much error carry over as we can (we plan on providing an assessment of error throughout the project if requested).

Ichnology

Ichnology accentuates sedimentological interpretation and is very useful in the fields of paleoecology, sequence stratigraphy, basin analysis, and reservoir characterization.

Applied Ichnology is one of the better methods of confirming or improving an interpretation of a paleoenvironment. By studying the different groups of trace fossils found in core, a basic environmental interpretation can rapidly evolve into a far more advanced and complex understanding of a paleoenvironment. By integrating ichnological and sedimentological information from core and outcrop we can gain insight into the depositional environment on either side of an observed unconformity. Qualiterra provides core and outcrop based ichnological assessment and skillfully ties the data into any other obtained or provided data.

Ichnology is also very useful to determine probable vertical and horizontal anisotropy. By accurately delineating ichnofacies and the associated environments we can predict likely vertical and horizontal changes in lithology. We apply these concepts to augment other data sources and to help determine appropriate sample selection in other analytical methods.
