Mud log — A Mud log is a graphical representation of the ROP (Rate Of Penetration), lithology, hydrocarbons and other drilling parameters generated while drilling an oil well. The act of gathering this information is considered mud logging and is done by… … Wikipedia
Spontaneous potential logging — The spontaneous potential log, commonly called the self potential log or SP log, is a measurement taken by oil industry well loggers to characterise rock formation properties. The log works by measuring small electric potentials (measured in… … Wikipedia
Gamma ray logging — is a method of measuring naturally occuring gamma radiation to characterize the rock or sediment in a borehole. It is sometimes used in mineral exploration and water well drilling, but most commonly for formation evaluation in oil and gas well… … Wikipedia
Wireline Logging — consists of measuring and recording the physical properties of the rocks in oil wells. Logging consists of introducing sensors in a borehole via a wireline , an electromechanical cable. Power and control is provided to the sensors inside the… … Wikipedia
Resistivity logging — is a method of characterizing the rock or sediment in a borehole by measuring its electrical resistivity. Resistivity is a fundamental material property which represents how strongly a material opposes the flow of electric current. In these logs … Wikipedia
