Description

The spontaneous imbibition Amott test consists of placing an oil-saturated core sample in a brine filled Amott cell. An adequate time between brine filling and sample immersion is necessary to ensure a constant, homogeneous temperature profile in the brine. The volume of oil expelled can accurately be measured by reading the graduation on the cell. The apparatus is comprised of a sealed glass container and a graduation tube located above it. Conversely, the spontaneous drainage Amott test consists of placing a water saturated core sample in an oil-filled Amott cell. An adequate time between oil filling and sample immersion is necessary to ensure a constant, homogeneous temperature profile in the oil. The volume of water expelled can accurately be measured by reading the graduation on the cell. The apparatus is comprised of a sealed glass container, a graduation tube located below it, and a stand to support the assembly. Optional high temperature Amott cells are also available.
