How much sample do you need for analysis?Find out how we prepare your samples.
The amount of sample we require varies depending on the analysis you would like us to undertake:
- SR pyrolysis – TOC, RE/Hawk - 2-3 g washed/dried cuttings or core sample
- Vitrinite reflectance – ca.10 g washed/dried cuttings or core sample
- Solvent Extraction with subsequent GC, GCMS and isotope analyses - 15-20 g washed/dried cuttings or core sample
- Oil/condensate analysis - 3-5 ml
- Gas analysis - test gas transformed to Isotubes is preferred
Please contact us for a discussion about how we can help you select the most appropriate analysis technique.
How long does analysis take?
Turnaround time is dependent on the number of samples analysed and amount of interpretation of the data. The following figures should be considered as guidelines only. All estimates are from receipt of samples and / or work-order from client confirming work.
- SR pyrolysis – TOC, HI RE/Hawk– ca 2 weeks
- Vitrinite reflectance – 6-8 weeks
- Solvent Extraction with subsequent GC, GCMS and isotope analyses - ca. 6 weeks
- Gas analysis (composition and isotopes) - ca. 3-4 weeks
- Standard Oil analyses - ca. 4-6 weeks
Where will the analysis be carried out?
All geochemical analysis are performed in-house in APT’s well-equipped and state of the art geochemical laboratories in Oslo, Norway. The optical analyses (i.e. vitrinite reflectance and visual kerogen) are carried out in our UK laboratory in North Wales.
What data do you have that we can license now?All available studies can be seen here.
We have a range of carefully QC'd databases and data reports that you can license now for use in your studies. These can all be found through the link below.

What information do you need to run a 1D basin model?Basin modelling - data requirements
We can run a set of 1D models to do an evaluation of the maturity of your area prior to setting up a full 3D model if it is deemed appropriate.
Ideally we will utilise the following for each well:
- Stratigraphic tops
- Temperature data (BHT / DST)
- Vitrinite data
- Source rock data
- Pressure data
We are able to extract much of this information from the well completion reports but any data you can provide will assist us in ensuring consistency with your projects.
What information do you need to run a 3D basin model?Basin modelling - data requirements
Running a 3D model requires a series of depth surfaces over the area you wish us to investigate. These will need to cover any key prospects you have plus the likely source kitchen areas.
As a minimum we will need depth maps for the source rock and reservoir intervals but being able to use all of the available surfaces will enable a more complete setup to be created which honours the geologic model.
Inputs may include:
- Palaeobathymetry maps
- Environment of deposition information and maps
- Fault polygons
- Source rock outlines
- Reservoir outlines
- Reservoir properties
- Top and / or fault seal details
- Salt mapping
- Prospect and lead polygons
How does APT ensure the 1D and 3D models are well calibrated?Basin modelling - calibration
We run through a thorough process to ensure all of our basin models are calibrated carefully to the QC'd input data. This data is commonly in the form of DST or Horner corrected bottom hole temperatures and vitrinite data.
APT always aims to match models to actual field and shows data through use of our high quality PVT database (APvT).
Can you integrate the lab analysis with our in-house data?Interpretation of Geochemistry Data
APT provide a full integration service where our experienced technical staff can help put the results of the laboratory analysis into context if you wish. This can be in the form of fully integrated basin models, Hot Spot (Zetware) databases and fully integrated reports.
We would be very happy to discuss how we can best integrate all of your data, new and existing, to gain the most valuable insights.
