Abstract:
1. A method for performing reservoir engineering, comprising: generating a geological model of a reservoir including a geological horizon; obtaining an offset relative to the geological horizon; positioning a wellbore equipment item in a well completion design based on the offset; positioning a reservoir operation relative to the geological horizon in the well completion design, wherein the reservoir operation comprises at least one selected from a group consisting of hydraulic fracturing, an oilfield perforation operation, acidization, a chemical treatment, and a cement squeeze; calculating an absolute position of the wellbore equipment item in the well completion design based on the offset and a location of the geological horizon in the geological model; updating the geological model to generate an updated location of the geological horizon; updating the absolute position of the wellbore equipment item in the well completion design based on the offset and the updated location of the geological horizon; and simulating a simulation case comprising the geological model and the well completion design after updating the absolute position of the wellbore equipment item.
