Introduction to Well Log Interpretation: Finding the Hydrocarbon,ocarbon production that are addressed by well logs. The borehole environment is described in terms of its impact on the electrical logging measurements, and all of the qualitative concepts necessary for simple log interpretation are presented. Without going into the specifics of the logging measurem

Basic Resistivity and Spontaneous Potential,formation. These measurements deal with the resistivity of the formation or the measurement of spontaneously generated voltages. These voltages are the result of an interaction between the borehole fluid and the formation with its contained fluids. Historically, the first logging measurements were e

Resistivity: Electrode Devices and How They Evolved,f one type of electrical logging tool: electrode devices, so named because the measurement elements are simply metallic electrodes. These devices utilize low-frequency current sources, in most cases below 1,000 Hz. The historical progression from the normal device to traditional focused dual laterol

Other Electrode and Toroid Devices,f the invaded or flushed zone .. Historically, the first use of the invaded-zone resistivity was, in the absence of any other measurement, to make an estimate of the formation porosity. Since then . has found many applications. In earlier chapters we saw that ., when compared with ., gives a visual

Resistivity: Induction Devices,ents have been made in electrode tool design to compensate for the problems. However, conductive borehole mud does provide one advantage: it effectively places the current and voltage measurement electrodes into electrical contact with the formation whose resistivity is to be measured.
