3D basin model

Source rocks

One of the most basic questions in the search for oil and gas is:

Where does the oil/gas come from, that is, what is its source rock?

This in turn raises all sorts of other issues, such as:
  • The type of oil/gas generated – source rock maturity and quality
  • The quantity of oil/gas generated – source rock richness
  • The journey of the oil/gas from source rock to reservoir rock – migration pathway
  • When the oil/gas was generated in relation to the reservoir rock - timing and charge
3D model3D basin modelling facilitates the simulation of hydrocarbon generation.

To reduce exploration risk, a picture needs to be drawn of generation, migration pathways and charge history, and the prediction of quality and quantity of generated hydrocarbons. This is achieved by basin modeling.

Robertson has the wide ranging skill-set to address all these problems, including:

  • Source rock and thermal maturity evaluation
  • Oil, condensate and gas characterization
  • Oil-oil and oil-source rock correlation
  • Thermal and migration modeling in 1D, 2D and 3D, using PetroMod, Trinity, Genesis and KinEx

Oil seeps

We specialize in surface geochemistry, investigating offshore seeps to determine whether they are from shipping or other forms of pollution, or are a natural phenomenon that may point to the presence of a regional source rock.

Our Satellite Mapping group provides complementary services and products based on the remote sensing of sea surface slicks and their correlation to natural hydrocarbon seeps.

Reservoir geochemistry

Our reservoir geochemistry capability has a number of uses, including the evaluation of reservoir compartmentalization, hydrocarbon charge history and production allocation. Innovative reservoir geochemistry solutions have been developed for determining the variation in and possible sourcing of reservoir fluids, produced water and bitumens. Seeps data and source rock analyses, for example, are key factors in petroleum systems evaluation.
