microcylindrical log
Oil & gas; Oilfield
An electrode device with small spacings from which the current flow, and hence the measurement, is focused a short distance into the formation. The microcylindrical log measures ...
microspherical log
Oil & gas; Oilfield
An electrode device with small spacings from which the current flow, and hence the measurement, is focused a short distance into the formation. The microspherical log measures the ...
microlaterolog
Oil & gas; Oilfield
An electrode device with small spacings from which the current flow, and hence the measurement, is focused a short distance into the formation. Introduced in 1953, the ...
array laterolog
Oil & gas; Oilfield
An electrode device with multiple current electrodes configured in several different ways to produce several different responses. A typical array consists of a central electrode ...
oilfield battery
Oil & gas; Oilfield
An electrochemical source that provides electrical power to a downhole or surface tool used for determining the location or assisting in the extraction of hydrocarbons. Unlike a ...
hybrid scale
Oil & gas; Oilfield
An early scale used for the presentation of resistivity logs. The scale has two parts, equally divided about a midpoint. The left part is linear in resistivity, for example 0 on ...
fast-formation arrival
Oil & gas; Oilfield
An early signal in a cement-bond log. In some formations, particularly carbonates of low porosity, it is possible that the first acoustic signal to arrive at the receiver passes ...
