    Why Venezuela is Alberta's biggest competitor | Oil Sands

    Venezuela uses conventional heavy oil production methods such as water-flooding or CHOP (Cold Heavy Oil Production), where oil flows to long horizontal wells with a large number of multi-lateral branches, without the use of heat or steam.

    History of the Venezuelan oil industry

    Venezuela is one of the world's largest exporters of oil and has the world's largest proven oil reserves at an estimated 296.5 billion barrels (20% of global reserves) as of 2012.. In 2008, crude oil production in Venezuela was the tenth-highest in the world at 2,394,020 barrels per day (380,619 m 3 /d) and the country was also the eighth-largest net oil exporter in the world.

    Extraction of petroleum

    For example, see Midway-Sunset Oil Field, California's largest oilfield. Tertiary recovery begins when secondary oil recovery is not enough to continue adequate extraction, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil. When prices are high

    Venezuela's Orinoco tar sands are significantly less viscous than Canada's, so the oil sands there can be extracted using conventional oil extraction methods, giving it a considerable advantage over the Northern American rival in terms of capital requirements and extractions costs. Countries with the Largest Proven Oil Reserves


    Over the past decade, Venezuela has capitalized on the massive oil reserves at its disposal and climbed its way to the top of the world's oil-producing nations. Part of their vault to the top was caused by the discovery of oil sands, much like the ones in Canada; as well as conventional oil/natural gas deposits.

    Why is Venezuela, which has the largest reserves of crude oil

    Following are some reasons: 1. The cost of producing a barrel of crude oil in Venezuela is higher than other top oil producing countries. Even if Venezuela starts pumping more oil, it will eventually lead to oversupply and the crude oil prices wil...

    Oil shale reserves

    Oil shale deposits range from small presently economically unrecoverable to large potentially recoverable resources. Defining oil shale reserves is difficult, as the chemical composition of different oil shales, as well as their kerogen content and extraction technologies, vary significantly. The economic feasibility of oil shale extraction is

    The Best Cannabis Extraction Methods for Marijuana

    Instead of butane hash oil, some manufacturers opt to produce propane hash oil. In this method, liquid propane is used in the place of butane. Here, high pressure keeps the propane liquefied and extraction occurs at a lower temperature, because propane's boiling point is less than butane's.

    Oil sands

    These methods usually use more water and require larger amounts of energy than conventional oil extraction.
