Transcripción del resumen publicado por el autor: Cold Heavy Oil Production with Sand (CHOPS) has been applied with very good success to enhance heavy oil production in Canada, China, Venezuela and Kazakhstan. Based on existing laboratory and field information and case histories, the most important physical processes enhancing cold production have been reviewed, summarized and quantified. Several sanding models are developed, including a new porosity cap model for failure propagation, as well as a semi-analytical elastoplastic stress model coupled with an unsteady pressure model for foamy oils. The mechanisms for oil rate enhancement by CHOPS, such as porosity and permeability enhancement that arise from sand removal, propagation of the elastoplastic (remolded) zone, increase of oil velocity relative to the matrix and the effects of foamy oil behaviour, are quantitatively described and compared. The proposed model can be applied to predict how much additional oil one might expect for a given amount of produced sand. It might also serve as a tool for optimizing cold heavy oil production while nevertheless keeping the sand flux at a low level, which could reduce operating expenses such as limiting sand disposal costs. 4 Journal of Canadian Petroleum Technology 46 ARTICULO Petróleos pesados 22736 Extracción de petróleos pesados 10586 Han, G. 27294 Bruno, M. 39179 167679 167679 http://www.terralog.com/article/CIPC2004_008_Han_CHOPS.pdf 0 0 0 0 235498 BVIAPG BVIAPG 2026-03-05 200042431 0 200042431 2026-03-05 14:47:08 2026-03-05 ARTICULO
