The Western Canada Sedimentary Basin contains some of the largest oil and gas reserves on earth, extracted using world-leading knowledge and technology.
At 1.4 million square kilometres, larger than the entire country of Peru, the vast WCSB accumulation of sedimentary rock stretches from the Rocky Mountains to the Canadian Shield to the southwest corner of the Northwest Territories.
The wedge-shaped geological structure is roughly six kilometres thick under the Rocky Mountains and thins to zero at its eastern margin in Manitoba and northern Saskatchewan.
Over the decades, geologists like Nicole Renella of Cabra Consulting, along with countless geophysicists, engineers and technologists, have developed sophisticated methods for discovering and producing oil and gas from porous rock.
