WebIn the late 1940s, induction log was developed, which works in nonconductive oil-based mud environments. Common logging tools and techniques used in the oil and gas industry are as follows: • Resistivity logs: Water is a better conductor of electricity than oil and gas. WebThe dual-induction log reacts as follows: The shallowest measurement, the SFL log, sees the near zone that's invaded by mud filtrate and regis- ters a high resistivity. The intermediate measurement, the medium induc- tion log, sees the …

"WebJun 24, 2015 · The SP log is typically scaled at 100 mV per log track. If the resistivities of the mud filtrate and formation water are similar, the SP deflections are small and the curve is rather featureless. An SP curve cannot be recorded in holes filled with nonconductive muds, such as oil-based muds (OBMs). Contents 1 Origin of the SP " - Flushed oil effect induction log
