Core Description

Our in-house expertise in core-description covers the full spectrum of depositional environments from fluvial and deltaic/shoreface systems to deepwater deposits, as well as carbonate rocks.

Advantages of using our core-description services:

  • Expertise in both conventional and unconventional cores
  • High resolution WellCAD core description in client-specific display layouts
  • Comprehensive core report with detailed statistical analyses
  • Digital archive of extracted core-data in editable format
  • Accurate ‘Core-shift’ for well-logs through appropriate calibration
  • Integrated reservoir characterization for lithofacies and depofacies
  • Cost effective, on time delivery of world-class products

Our costs are significantly lower than that of Core Laboratories, Terra Tek, Fugro Robertson, ICHRON or anyone in the U.S and Western Europe. But our quality of work is superior because of our integrated approach- Applied Stratigraphix goes beyond the routine core descriptions by solving critical problems of understanding depositional environments, sandbody geometry, reservoir heterogeneity and interconnectivity. If you are not satisfied, we will not charge you for the hours worked!

Our vast experience in core description from basins around the world includes:

  • North Sea & Offshore Mid-Norway
  • Williston Basin
  • Barents Sea
  • Kohat-Potwar Basin
  • West Africa (Angola & Nigeria)
  • Southern Indus Basin
  • Surma Basin Bangladesh
  • Paradox Basin
  • Powder River Basin
  • San Joaquin Valley

All our core description templates are custom-made in WellCAD according to client-need, and fit for purpose. However, here are some typical options of core-description layout criteria we have used in the past:

Sedimentology

This will show grain size, sedimentary structures, and trace fossil suites. Besides a graphic representation you will receive a description, process interpretation and environment of deposition.

Sequence Stratigraphy (Cycles)

If you have biostratigraphic data we can mark sequence boundaries and maximum flooding surfaces directly on the core. Alternatively we can also mark key sequence stratigraphic surfaces in core and add systems tracts. Conversely, if you have regional stratigraphic markers/tops (from well logs or seismic data) we can upload those to our core-description panel for comparison.

Bioturbation Index

A bioturbation index shows the intensity of sediment churning and the preservation of original sedimentary fabric. Bioturbation can both enhance and degrade reservoir quality and we recommend a column that shows the BI such that you can determine the effect of bioturbation on the porosity and permeability of your reservoirs.

Porosity-Permeability & Saturation Data

We may incorporate available porosity-permeability and saturation data (pks) in order to graphically demonstrate the relationship between rock-type/lithofacies/depofacies and reservoir quality.

Fractures

We can document fracture type (extension vs shear), aperture size, mineral fill, porosity within fractures, density, intensity, orientation and determine the stress field in your area of interest. After having described fractures we can provide a diagnosis whether fractures might influence production from your wells. If this is the case, we then recommend a detailed fracture study. Our specialization is restricted to sedimentology and stratigraphy. But we can align you with the right contacts for detailed fracture studies for increasing production from your fractured reservoirs (e.g., such world experts John Lorenz and Scott Cooper at Fracture Studies).
