HI Rob, AU Etal

The Mention in the last report of Fluorescence and Gas ,
from the show at Cris R III .(Secondary Target )

"Indicative of Oil and comprises sample fluorescence at 50%
accompanied by a significant gas increase in the mud
Thanks to Crain's Petrophysical Handbook :
Note : Significant

"Gas in the mud system may indicate the penetration of either an oil or a gas reservoir. The first objective is to detect the presence of the gas with some form of total gas detector. The second step is to break down the gas into its components with a gas chromatograph to see if the gas comes from an oil or gas show."

"If gas is seen on the log in quantities larger than the average background, the question arises, "Is this a significant increase and does it indicate a gas or oil zone?" Similarly, "How much fluorescence in the cuttings indicates an oil zone?" The simple and quick answer to both of these questions is, "We don't know, yet!"
