Favourite paper:  Dick Woodhouse's "Accurate Reservoir Saturations from Oil-Mud Cores: Questions & Answers from Prudhoe Bay & Beyond"  The Log Analyst May-June 1998.  Why?  At last a calibration reference for the log-analyst's eternal headache.

Favourite topic: The old chestnut  "The confusion regarding total vs. effective porosity is due primarily to the longstanding inconsistency between core companies use of the term "effective porosity" to mean "Interconnected pores", vs. mainstream petrophysicists (Archie, W&S, Shell, NMR literature) use of "effective porosity" to mean (Total porosity - Clay bound water).  It does not matter what the porosity is called - the important issue is whether logs are calibrated to a fundamental reservoir property which is directly measured and accurate."  Why? Sit back and enjoy the fun in meetings when someone mentions "effective" porosity.  iprc_91.pdf

Core Analysts: Please refer to oven dried helium porosity as "interconnected porosity" or simply what it is, "oven dried helium porosity"  Eschew the loaded and misleading "effective porosity" which means something quite different to your users.

Favourite frontier: Perfecting the sequential logic for the evaluation of complex carbonate or fractured reservoirs which efficiently exploits today's evolving data sets.  Why?  Intellectually rewarding and desperately needed by most companies.
