It is waterproof, cannot be altered without causing damage and it has the following security elements: uv content, micro-letter protection, metallised paper.

It shall include all emissions of S and NOx which occur during the production of pulp and paper, including steam generated outside the production site, except those emissions related to the production of electricity.

Vapours displaced by the delivery of petrol into storage installations at service stations and in fixed-roof tanks used for the intermediate storage of vapours must be returned through a vapour-tight connection line to the mobile container delivering the petrol.

1. Displacement vapours from the mobile container being loaded must be returned through a vapour-tight connection line to a vapour recovery unit for regeneration at the terminal.

Alberta's oil reserves are sourced in the following ways: by strip mining shallow bitumen sands deposits, where 90% recovery of original oil-in-place is achieved; by in situ extraction of bitumen sands in deeper deposits using cyclic steam stimulation, now achieving recovery factors of 35% to 40%; by steam-assisted gravity drainage, typically achieving recovery factors exceeding 50%, and sometimes up to 70%; by in situ extraction of bitumen carbonate deposits, where two successful commercial-scale pilot projects in the Grosmont deposit are now both proceeding to full scale-development; and by multiple fracking of horizontal wells in ...[+++]tight oil shales containing a large oil resource little developed as yet, but classed as “proved undeveloped”, based on success exploiting analogous tight oil shales in the U.S. These recent developments and improvements in recovery factors indicate Alberta's proved oil reserves are 848 billion barrels.
