  2. Radioanalytical chemistry - Wikipedia

    en.wikipedia.org/wiki/Radioanalytical_chemistry

    The carrier is of the identical element but is non-radioactive. The carrier and the radionuclide of interest have identical chemical properties. Typically the amount of carrier added is conventionally selected for the ease of weighing such that the accuracy of the resultant weight is within 1%.

  3. Reservoir simulation - Wikipedia

    en.wikipedia.org/wiki/Reservoir_simulation

    Landmark Nexus – Nexus is an oil and gas reservoir simulator originally developed as 'Falcon' by Amoco, Los Alamos National Laboratory and Cray Research. It is currently owned, developed, marketed and maintained by Landmark Graphics, a product service line of Halliburton. Nexus will gradually replace VIP, or Desktop VIP, Landmark's earlier ...

  4. Petrophysics - Wikipedia

    en.wikipedia.org/wiki/Petrophysics

    As core samples are the only evidence of the reservoir's formation rock structure, the Core analysis is the "ground truth" data measured at laboratory to comprehend the key petrophysical features of the in-situ reservoir. In the petroleum industry, rock samples are retrieved from the subsurface and measured by oil or service companies' core ...

  5. Hydrological model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_model

    The linear-reservoir model (or Nash model) is widely used for rainfall-runoff analysis. The model uses a cascade of linear reservoirs along with a constant first-order storage coefficient, K , to predict the outflow from each reservoir (which is then used as the input to the next in the series).

  6. Flow chemistry - Wikipedia

    en.wikipedia.org/wiki/Flow_chemistry

    Laboratory scale flow reactors are ideal systems for using gases, particularly those that are toxic or associated with other hazards. The gas reactions that have been most successfully adapted to flow are hydrogenation and carbonylation , [ 9 ] [ 10 ] although work has also been performed using other gases, e.g. ethylene and ozone .

  7. Column chromatography - Wikipedia

    en.wikipedia.org/wiki/Column_chromatography

    Binding between the target molecule to be separated and the binding molecule on the column beads can be modeled using a simple equilibrium reaction K eq = [CS]/([C][S]) where K eq is the equilibrium constant, [C] and [S] are the concentrations of the target molecule and the binding molecule on the column resin, respectively. [CS] is the ...

  8. Energy carrier - Wikipedia

    en.wikipedia.org/wiki/Energy_carrier

    Energy carriers are produced by the energy sector using primary energy sources. In the field of energetics, an energy carrier is produced by human technology from a primary energy source. Only the energy sector uses primary energy sources. Other sectors of society use an energy carrier to perform useful activities (end-uses). [3]

  9. Microcarrier - Wikipedia

    en.wikipedia.org/wiki/Microcarrier

    There are several types of microcarriers that can be used, the selection of which is crucial for optimal performance for the application. Early in microcarrier development history, synthetic materials were overwhelmingly used, as they allowed for easy control of mechanical properties and reproducible results for the evaluation of their performance.
