Orinoco Belt Wikipedia The Orinoco Belt is a territory in the southern strip of the eastern Orinoco River Basin in Venezuela which overlies the world's larg

The case study is based on experience in the Orinoco Belt of Venezuela. A cluster of wells that produced 12,188 BPD generated approximately 894 kg/D of sand, making it necessary to handle the sand in surface facilities. The sand must be retained because of the high-viscosity oil production.

Heavy oil properties are based on an integrated database of heavy oil from 31 wells distributing throughout the Orinoco heavy oil belt. Apart from some well data from published relative literatures (Gassani and Eglinton 1991; Galarraga et al. 2007; López and Mónaco 2010, 2017), most of the data are collected from oilfields in heavy oil belt.We compile the oil source …
