Pertaining to techniques in which the same quantity is measured at different times in the life of a reservoir. Normally the only change in a time-lapse measurement or survey will be due to changes in ...

Uranium

Oil & gas; Oilfield

An element with an atomic number of 92. The 238 U isotope is radioactive and decays with a half-life of 4. 4 * 10 9 years through a series of intermediate isotopes to a stable isotope of lead. The ...

Thorium

Oil & gas; Oilfield

An element with an atomic number of 90. The 232 Th isotope is radioactive and decays with a half-life of 1. 4 * 10 10 years through a series of intermediate isotopes to a stable isotope of lead. ...

Potassium

Oil & gas; Oilfield

An element with an atomic number of 19. The 40 K isotope is radioactive, decaying with the emission of a single gamma ray of 1. 46 MeV with a half-life of 1. 3 * 10 9 years to give a stable isotope ...

Guard electrode

Oil & gas; Oilfield

An electrode on a laterolog sonde that focuses the current sent by the central current-emitting electrode (A0). The guard electrode is held at the same potential as A0, thereby forcing the current ...

Saturation equation

Oil & gas; Oilfield

An equation for calculating the water saturation from resistivity and other logs. There are many saturation equations. Practical equations are all extensions of the Archie equation, which is valid ...

Structural analysis

Oil & gas; Oilfield

An examination of a geological scenario to understand the geometry and spatial arrangement of rocks. The structure or deformation can include many mechanisms, such as folding, faulting and ...
