Annotation:
The article, by applying mathematical three-dimensional modeling, analyzes the factors influencing the features of water ridges formation in various types of wells with horizontal completion technologies. In the commercial product Tempest more of AspenTech firm (until 2022 – Roxar), numerical experiments have been developed for horizontal, double-lateral and multilateral wells. The main types of problems that may occur during branched wells operation are formulated for further research in conditions of a contact reservoir with underlying water. The factors of influence of reservoir heterogeneity, wells designs and technical pairs of wellbores are revealed.
