Ann: Fluid sample analysis confirms rich gas-condensate discovery, page-147

Yourself and Kiwigeo seem to be using the scale referred to by Dindoruk below. I am interested to know if the article attached further below is relevant to Mukuyu, in terms of a "wet gas" of a leaner CGR surprisingly being more closely linked to the presence of oil...with particular reference to Kiwideo's seemingly dubious questioning of presence of light oil in samples? (Or are dew points, differing pressures and hydrocarbon types too variable to compare to this example)?

Dindoruk (2012) has further classified the condensates based on their liquid content as lean if the condensate to gas ratio (CGR) is less than 50 STB/MMscf; medium if CGR is greater than 50 and less than 125 STB/MMscf; rich if CGR is greater than 125 and less than 250 STB/MMscf and very rich or near critical if CGR ...

Dry Gas, Wet Gas, Condensate and Condensables

At a recent industry conference a poster summarised aspects of the petroleum systems in a particular basin. The authors noted that some reservoirs contained "dry gas" while others contained "wet gas". The boundary between the two was not defined but it was clear from the context that the distinction reflected the condensate content: gases having more than about 20 bbls/MMscf of condensate were classified as "wet".

Note the wide variation related to condensate composition. In particular, note that the very light condensates B and C (yellow dots) show low dew point pressures even though they have a high CGR (~ 95 bbls/MMscf, or GLR ~ 10,000). This reflects the high mutual miscibility of the liquids and gases for these fluids. It is often assumed that finding a high CGR gas in a shallow reservoir increases the likelihood of a finding oil in the system. In fact, the reverse is true: If the liquids are light enough to remain in the vapour phase even in high concentration, there are few oil range molecules present. Condensates of type "G" (43 bbls/MMscf) are much more likely to be found in association with oil.
