Spontaneous Potential
Spontaneous potential (SP), also called self potential, is a naturally occurring electric potential difference in the Earth, measured by an electrode relative to a fixed reference electrode. Spontaneous potentials are often measured down boreholes for formation evaluation in the oil and gas industry, and they can also be measured along the Earth's surface for mineral exploration or groundwater investigation. The phenomenon and its application to geology was first recognized by Conrad Schlumberger, Marcel Schlumberger, and E.G. Leonardon in 1931, and the first published examples were from Russian oil fields.

Famous quotes containing the words spontaneous and/or potential:
“They [creative children] ask more questions than most children. They’re usually spontaneous and enthusiastic. Their ideas are unique and occasionally strike other kids as weird. They’re independent. Not that they don’t care at all what other kids think, but they’re able to do their thing despite the fact that their peers may think it’s strange. And they have lots and lots of ideas.”
—Silvia Rimm (20th century)
“Democracy is timelessly human, and timelessness always implies a certain amount of potential youthfulness.”
—Thomas Mann (1875–1955)
