Formation Oddities and Their Response on Wireline Logs


J.T. Costello, Triad Oil Co



Five examples are presented of formational abnormalities in wire-line log- ging, namely — 1) a low resistitivity oil producing zone, 2) a radioactive reef, 3) a pyrite sand, 4) a thin but prolific hydrocarbon sand, and 5) a "well that wasn’t". Explanations are suggested for each oddity. It is hoped that other formational wire-line log peculiarities can be brought to the att- ention of the Canadian Well Logging Society.
