<p>Several sources of uncertainty need to be taken into account when assessing the static volume of hydrocarbons in a deposit. A base case is selected for each source of uncertainty. For each source of uncertainty, a probability distribution of the static volume is estimated when said source varies while the other sources comply with the base cases thereof. A conversion table is constructed, of which each row has, for each source of uncertainty, a quantile value corresponding to a volume value according to the probability distribution estimated for this source and, furthermore, having a resultant value of the static volume calculated on the basis of the volume values associated with the quantile values of the row. A row of the conversion table which has a resultant value of the static volume of hydrocarbons that is equal or closest to the target value of the static volume is selected to adjust the sources of uncertainty in a geological model.</p> |
