Cold Heavy Oil Production with Sand (CHOPS) involves the deliberate initiation of sand influx during the completion procedure, maintenance of sand influx during the productive life of the well, and implementation of methods to separate the sand from the oil for disposal. The sand is produced along with oil, water and gas and separated from the oil before upgrading to synthetic crude.
Rockfield have engaged on numerous projects in relation to CHOPS to allow a better understanding of the phenomena governing the production performance of the field. Utilising our software, Elfen can enhance the field scale model to capture the observed field directional behaviour. Incorporating the field scale material property distribution to release more heterogeneous property distribution. Utilising Elfen’s multi-phase flow simulator instead of single-phase flow simulator. Applying progressive modelling methodology from field initialization to longer term production and injection of 4 years. Combining Mechanical, Mass Trasnport and two-phase flow mechanisms.
