The Company
Eucalyptus Consulting Inc. provides timely digital geological evaluations which your staff may not have the opportunity to execute in their busy daily schedule.

Eucalyptus Consulting provides clastic reservoir evaluations that are ‘upload ready’ for Petra or Geographix (or for reservoir simulation). Our evaluations follow typically ten distinct steps (stages). Although the order of the steps is well established, we may vary the emphasis on each step depending on whether we deal with detailed pool evaluations or regional studies, and of course depending on client requirements. Because of these ingrained steps our time estimates are often on target and we typically meet our deadlines.

Finally, we offer on a ‘a-la-carte’ or modular basis the same services that constitute our overall project steps : e.g. log normalization; thin section analysis; core examination and description.

Detailed core examination and description
We examine core both macroscopically and with a Zeiss Stemi cuttings microscope. We examine for sedimentary structures; grain or crystal size and grain size distribution; porosity and porosity distribution; shale volume (dispersed and sand/shale bed ratio); mineralogy of framework and cements (using); grain sorting and rounding. Our description includes facies characterization and depositional analysis.

The description is presented as a depth plot in WellSight formatting, LAS format and/or in PDF format. Each core is digitally photographed supplemented with detailed photography of pertinent features. When requested, we can select samples for petrography and core analysis (both special and routine). Our upgraded Zeiss Stemi Microscope can magnify up to 125x and deliver micrographs.
Cuttings examination and description
We examine drill cuttings and interpret the lithology of the cuttings sample interval. A cuttings sample typical contains a large number of cavings and other drilling mud additives such as LCM (lost Circulation Material). We will select and describe from the sample those cuttings that we interpret to represent the actual sample intervals and our description, when presented in LAS format can be used like other wireline data and interpretations. Clients may import grain size data, lithology, porosity estimates, VSH measurements and permeability estimates into GIS programs such as PETRA or Geographix.

We measure and describe, grain or crystal size, porosity, shale volume (dispersed), mineralogy of framework and cements (using a cuttings microscope), grain sorting and rounding, facies estimate

(requires also core examination in nearby wells). The description is presented as a depth plot using WellSight software, LAS formatting and/or in PDF format. When requested, we can select samples for petrography. Our Zeiss Stemi Microscope can magnify up to 125x (specially upgraded for very fine grained or small pore size reservoirs) and has the capacity to deliver micrographs. Our Leica MZ12.5 stereomicroscope has an 8x – 100x magnification with excellent photographic capabilities.
Project updates
We offer project updates for 20% of the original project price at the client’s discretion. This is not on a subscription basis, so these updates maybe requested when the client decides.
Petrographic analysis and reports
Thin section analysis
We provide both qualitative and quantitative thin section analysis using a Zeiss Axioscope 40 with magnification up to 400x and a Nikon Eclipse polarized petrographic microscope.

The qualitative analysis provides 4 micrographs (photos taken of the microscope’s field of view) to provide an overview of the sampled rock as well as larger magnification micrographs of pertinent reservoir features as well as a short description of each micrograph. More micrographs can be provided upon client request.

The quantitative analysis is a 100 grain point count of the overall thin section or if heterogeneous of up-to 3 different rock modes, within an individual thin section sample. A numerical spreadsheet is provided for each sample (in Excel format). When sufficient samples are analyzed the data is also summarized and analyzed to determine relationships such as Chert content versus grain size, Vsh versus total or effective porosity, grain size and facies, grain size and permeability, etc. Emphasis of this quantitative analysis is on detecting factors that may explain production performance as well as determining factors that affect petrophysical properties (radio-active minerals in framework, mineral composition presence of bitumen, etcetera).
X-Ray Diffraction (XRD) analysis
We can select and submit to a third party samples for XRD analysis and then interpret the results together with that of other petrographic data and/or in the context of a petrographic project or an integrated geological study. Alternatively, we can use client supplied XRD data to integrate into a petrographic or an integrated geological study.
Scanning Electron Microscopy (SEM) analysis
We can select and submit to a third party samples for SEM analysis and then interpret the results together with that of other petrographic data and/or in the context of a petrographic project or an integrated geological study. Alternatively, we can use client supplied SEM data to integrate into a petrographic or an integrated geological study.
Interpret special core analysis
We Interpret special core analysis data (e.g. capillary pressure and relative permeability data) in terms of pore throat size distribution, water saturation-porosity-depth above free water relationship; effective versus ineffective porosity, cumulative permeability fraction, fractional flow curve and other analyses.
Petrophysical Analysis
Our analysis typically integrates observations from detailed core examination, petrography and special core analysis with wireline log data to come up with an integrated petrophysical analysis – hence our corporate motto ‘From the Rock to the Log’. We also perform tailored petrophysical analysis.

We provide quality controlled log curves, including: curve editing, environmental corrections, depth shifting, and normalization. A quantitative log interpretation is available through providing quick-look, detailed single well or multi-well analyses. We provide Petrophysical analysis in clastics and carbonates by integrating various types of core analysis data and petrophysical data sets to support and improve reservoir characterization using TechLog, Prizm or PETRA software. Analysis can be done on individual wells or on a large number of wells (1000 or more) to determine reservoir lithology, porosity, fluid saturations, permeability, net pay, rock property estimations, and predict to hydrocarbon potential using both deterministic and multi-mineral approaches.

We provide petrophysical analyses of new and pre-existing wells in unconventional resources including shale oil, shale gas, and tight oil by providing complex mineralogy, geo-mechanic properties, TOC, and rock quality data. Results are presented in PDF formatted answer plots and/or as LAS files with raw curves and answer curves as well as a report explaining workflow and conclusions in electronic format.
Geological review of horizontal well bore placement
We review horizontal well data with deviation surveys, incorporating cuttings examination, normalized wireline data or answer curves from petrophysically analyzed offset wells to determine wellbore placement and potential completion or recompletion targets.
Geologic Evaluations/Mapping
We do confidential geological evaluations as requested by individual clients. Below is a short outline of how we approach our work.

At Eucalyptus we first examine the rocks themselves within their geographic and stratigraphic context and then use this knowledge to extrapolate reservoir properties (fluid saturations, porosity, etc.) using wireline logs. We test the results against production and reiterate the work where necessary. Subsequently, we map and discuss with the team possible exploitation strategies preferably with client input. The results are compiled in a final presentation with mapping, cross sections, etcetera which is available in electronic format.

Our integrated evaluation follows the workflow process discussed above. Because these stages are ingrained into our evaluation approach we typically meet our deadlines.
In-house courses
Eucalyptus offers a variety of courses and workshops. Some of these courses have also been presented internationally as well as through the CSPG Continuous Education programs.

We can present in house core workshops tailored to the need of individual clients. Examples of our industry courses are:
  • Reservoir Geology of Sandstones.
  • Regional Geology field school of the Belly River Formation in Central and Southern Alberta.

We have provided in house core workshops on reservoirs from the Belly River; Cardium; Viking; Glauconitic ; Horsefly;Nikanassin (Minnes; Cadomin; Dunlevvy); etcetera.
