Lactate was measured in a microphotometer (DR LANGE, Berlin) with commercially available kits (LCQ 140, DR LANGE, Berlin).
Vitrinite reflectance (Ro) was measured by an oil immersion lens and a Leixa MPV Compact II reflected light microscope fitted with a microphotometer. Measured Ro values in six wells are primarily between 0.5% and 1.2%, indicating that the Eocene source rocks have entered the mature generation stage (Figure 7).
