Heavy oil and tar sand - World distribution of heavy

2021-7-24  One of the largest petroleum reserves in the world is a heavy oil field in the Orinoco Belt in eastern Venezuela. Although sometimes called a tar sand reserve, this enormous heavy oil deposit is nonbituminous. The U.S. Geological Survey has estimated that the recoverable heavy oil in this reserve, concentrated in a strip some 700 km (435 miles) long by 60 km (37 miles) wide along the Orinoco ...

Case Study: Sand Separation in Surface Facilities for ...

2014-9-26  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.

Environmental impacts of oil sands - Energy Education

2021-6-18  The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel, negative environmental effects arise as a result of the extraction, upgrading, and processing of bitumen from the oil sands. Although some steps are being taken to reduce the severity of these impacts - such as reclamation - there are still associated ...
