The extraction of oljesand involves two primary methods: surface mining and in-situ recovery. Surface mining is
Processing oljesand into usable crude oil requires significant energy and water inputs, which has raised environmental
Economically, oljesand is an important resource for the energy industry, especially in Canada, where it contributes
Advancements in technology aim to reduce environmental impacts and improve extraction efficiency, but challenges remain. As
