Venezuela’s largest heavy-oil deposits are found primarily in the Faja del Orinoco Belt. These deposits exhibit a low production rate under the cold flow method. The objective of this study is to model the impact of steam injection on the fluid dynamics, geomechanics, and seismic attributes for the Faja del Orinoco steam-assisted gravity drainage p...
This study investigates whether thermally induced changes from steam assisted gravity drainage (SAGD) operations in a heavy oil sandstone reservoir are observable using seismic methods. Thermally induced changes can include stress changes, changes in characteristics arising from shear heating of heavy oils, and changes in fluid saturation and densi...
Steam Assisted Gravity Drainage (SAGD) is one of the technologies selected to economically increase the recovery factor from the very large accumulations of heavy oil found in the Orinoco Belt, Venezuela. This paper presents a geomechanical laboratory and field campaign to obtain the rock properties, estimate the in-situ stresses, and to evaluate t...
