Three-dimensional(3D) seismic surveys utilise 2D grids of seismic sources and receivers deployed on the ground surface. The seismic response of the ground is recorded as a time series corresponding to each source-receiver pair, and the wave propagation time becomes the third dimension of the data set.... If a 3D seismic survey is repeated at several time intervals, this historical time(as opposed to the wave propagation time) becomes a fourth dimension, hence the name 4D or time-lapse seismic. The 4D approach allows a detailed description of the evolution of the reservoir, but the overall cost of the survey escalates rapidly by repeating conventional 3D surveys.  4, record 1, English, - time%2Dlapse%20seismic

Afin d'obtenir une image plus précise et plus fiable du sous-sol, on emploie la technique de la sismique 3D [...] Elle permet même souvent de repérer directement les hydrocarbures dans les couches géologiques. Les récepteurs sont placés en nappes afin de construire une image du sous-sol en volume (en trois dimensions). La technique de la sismique 4D va plus loin encore, en faisant intervenir la quatrième dimension : le temps. Sur un gisement en production, on effectue plusieurs enregistrements successifs de sismique 3D, à intervalles de temps réguliers. La comparaison des enregistrements permet ensuite de suivre l'évolution du gisement pendant sa production.  4, record 1, French, - sismique%204D

A modeling process by which variation in a time series are assumed to be explained wholly by the historical trends of the data itself. In essence, the ARIMA modeling process consists of the autoregressive and moving average processes of the Auto-Regressive Moving Average(ARMA) Model process on data that have been Differenced to render them Stationary. The process uses variations of differencing and transformations to describe historical patterns in the data. Like the simpler ARMA model, forecasts made by an ARIMA modeling process consist of only a mathematical process of projecting inherent characteristics of trend, cycles, and seasonality into the future and incorporate no economic relatinships. Consequently, such models are not appropriate for impact analysis or for incorporating random "shocks", but may prove an effective estimation process when the trends in the historical data are relatively stable and well-behaved.  1, record 2, English, - auto%2Dregressive%20integrated%20moving%20average%20process
