  "term": "Gaussian collocated cosimulation",
  "field": "Oil and gas",
  "definition": "A geostatistical simulation technique used to generate multiple realizations of a primary variable, conditioned by a secondary variable that is sampled at the same locations. It assumes a Gaussian distribution for both variables and uses the correlation between them to improve the estimation of the primary variable. This method is applied when a densely sampled secondary variable, like seismic impedance, can inform a sparsely sampled primary variable, such as porosity.",
