Spontaneous potentials (SP) are usually caused by charge separation in clay or other minerals, due to presence of semi-permeable interface impeding the diffusion of ions through the pore space of rocks, or by natural flow of a conducting fluid through the rocks.
24 de jun. de 2015 · If the currents could be interrupted by hypothetical insulating plugs (see the upper part of Fig. 1), the potential observed in the mud would be the total spontaneous potential. This idealized SP deflection is called the static SP (or SSP).
27 de jun. de 2020 · El método (SP) – self-potential o potencial espontáneo pertenece a los métodos eléctricos y a los métodos geofísicos de prospección, y su estudio es importante como parte de la geofísica. En este artículo describimos los conceptos principales, aplicaciones e interpretación del método.
Spontaneous potentials are usually caused by charge separation in clay or other minerals, by the presence of a semipermeable interface impeding the diffusion of ions through the pore space of rocks, or by natural flow of a conducting fluid (salty water) through the rocks.
El potencial espontáneo estático (SSP) es igual al potencial electroquímico. Cuando la corriente fluye, el SP mide solamente la fracción de la caída de potencial que se produce en el pozo.
Spontaneous potential log, commonly called the self potential log or SP log, is a passive measurement taken by oil industry well loggers to characterise rock formation properties.
28 de jul. de 2016 · The spontaneous potential (SP) log was developed next and was presented along with resistivity logs. It is a measurement of the voltage difference between a movable electrode in the wellbore and a fixed electrode at the surface.
