3D-Geo Chem offer and provide services at both the exploration and reservoir levels, by addressing:

• The geochemistry of petroleum systems, chiefly the evaluation of source rock effectiveness (their ability to deliver hydrocarbons to prospects).  This involves the interpretation of analytical data to evaluate the quantity, quality and thermal maturity of generative organic matter contained within source rocks, and with which to calibrate burial and thermal history modelling of regional source rock maturity.  In addition, such data can offer valuable clues as to which hydrocarbon types (oil versus gas, dry gas versus wet gas, etc) might be expelled from the source rocks concerned, and which might therefore be expected to charge mapped prospects.  Armed with the results of this work, 3D-Geo can then integrate mapping products to develop expulsion and migration pathways to high-grade permits and quantify prospect risking.

• The geochemistry of known hydrocarbon occurrences (oils, gases and shows), which, as the end-products of the petroleum system, can provide valuable insights as to the provenance of hydrocarbons reservoired within a basin (by e.g. oil-source correlation), whether reservoired hydrocarbons are the result of more than one charge (from the same source rock at different stages of its maturity, or from more than one source rock), and the efficiency of the petroleum system(s) involved.

Such data may also indicate whether there are elements of their composition that may ultimately affect their deliverability during production (for example, whether they contain waxes, or whether the hydrocarbons have undergone any in-reservoir alteration, such as biodegradation or water-washing).  In addition, hydrocarbon geochemistry can be applied at a detailed reservoir scale to provide essential insights as to the connectivity and/or compartmentalisation of reservoir units prior to reservoir development and production planning.
