The Heyl & Patterson Blog, or simply the H&P Blog as it is known on social media, has been posting articles regularly since 2010. At Heyl & Patterson, our goal is to educate and inform you about the latest developments in your industries. This forum has covered topics as varied as the industries we serve, from explaining the inner workings of conduction dryers to examining how a railway across Colombia could compete with the Panama Canal. As the author of this blog, I've never broken the fourth wall, but I'd like to thank all of our subscribers for following us, and if you haven't yet read the Heyl & Patterson Blog, this is a good time to start.

The more efficient an oil sands operation is, the more profitable it can be. The crude by rail industry has become an important means of transporting oil within Canadian provinces, to the lower 48 states, and to Europe and Asia. Rail has become so vital because development of pipelines such as the Keystone XL have been delayed, and construction on pipelines for oversea exports is just getting under way.
Canada's oil sand deposits contain the world’s second largest oil resource, after Saudi Arabia. Surface mining can extract around 20% of the oil and currently covers about 342 square miles in the province of Alberta, roughly two-thirds the size of the city of Los Angeles. In their natural state, oil sands are loose particles that are a combination of clay, sand and water saturated with bitumen. Processing of this material fundamentally separates oil-bearing bitumen from the sand itself, and can also be referred to as bituminous sands.
A tailings pond is a temporary storage area for the leftover by-product materials from oil sands, shale gas and coal ash operations, and is often a discontinued mine pit that has been re-engineered with a dam and dyke system. The contents of the pond is a slurry, with large volumes of water, sand, clay, residual hydrocarbons, heavy metals, naphtha diluents and naphthenic acids, which are known as tailings. The various materials settle to different depths, but they can all be dredged and dried to reduce their volume and eliminate moisture.
