Chemostrat/Belloy Geologists

  • Operation of the latest hydrocarbon detection and analysis (Isotubes, Isojars, Chromat, XRF, XRD, TOC) by our Calgary wellsite geologists
  • Petrographic reservoir evaluation studies analyzing core and cuttings
  • Digital photography through the microscope to capture high resolution features and accurate measurements of the drill cuttings

Portable and Wellsite Shale Solutions

Belloy Geologists in association with Chemostrat Canada Ltd can provide fast turnaround elemental, mineralogical, magnetics and TOC data in the lab, in the corestore or at wellsite for geosteering, correlation, reservoir quality and completion optimisation.

Chemostratigraphy (or chemical stratigraphy) is a technique used to correlate sedimentary successions based on subtle changes in concentrations of key major, trace, and rare earth elements. Recent technological advances now enable determination of selected major and trace element concentrations from cuttings at a well site within minutes of the samples arriving at the surface. Comparison of the data obtained while drilling to information from previously drilled offset wells increases confidence in stratigraphic location of the bit. Once a stratigraphic geochemical characterisation is defined, it becomes possible to track a borehole while drilling subsequent wells. Chemostratigraphy also allows a real-time correlation framework to be constantly updated.

Once a vertical chemostratigraphic framework has been created, it is then possible to determine exactly which parts of the formation subsequent horizontal wells have penetrated. These data can be acquired in real-time at well site and used as a geosteering tool, or they can be acquired within a matter of days between drilling and completions operations to allow for any changes to be made to the completions program in light of mineralogy changes that may influence the fracturing fluids used or stages that can be omitted.
