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 conventional battery, ...

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 the left edge to 50 ...

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 through the formation ...

Loose emulsion

Oil & gas; Oilfield

An emulsion with large and widely distributed droplets. A loose emulsion can be easy to break.

Tight emulsion

Oil & gas; Oilfield

An emulsion with small and closely distributed droplets. A tight emulsion can be difficult to break.

Thermal neutron absorber

Oil & gas; Oilfield

An element, or mineral, that is particularly effective in absorbing thermal neutrons (neutrons with about the same energy as the surrounding matter, typically less than 0. 4 eV). The elements ...

Chemical neutron source

Oil & gas; Oilfield

An encapsulated radioactive material that emits neutrons for use in neutron porosity measurements. The most common source relies on alpha-beryllium reactions in a 241 Am-Be mixture. Beryllium ...
