An oil sands project
Our 100 percent-owned Christina Lake project is one of our two producing oil sands operations in northeastern Alberta, and is located approximately 150 kilometres southeast of Fort McMurray. The oil at Christina Lake is about 375 metres underground. It's so deep that we have to use specialized technology to drill and pump it to the surface. The technology we use is called steam-assisted gravity drainage (SAGD).
Construction of our pilot project at Christina Lake began in 2000 and first production occurred two years later. The project is expected to have a life span of more than 30 years.
Christina Lake currently has production capacity of 210,000 barrels of oil per day. Construction at the Christina Lake phase G expansion resumed in the first quarter of 2017, with activity increasing through the end of the year and into 2018. Phase G has approved capacity of 50,000 barrels of oil per day and is anticipated to begin production in the second half of 2019.
Today, our Christina Lake project is one of the most efficient SAGD facilities in the industry. It has a low steam to oil ratio (SOR), which means it uses less water and natural gas and creates fewer greenhouse gas emissions to produce a barrel of oil than other oil sands facilities of the same size. In 2018, the project had an average SOR of 1.9. This means we used less than two barrels of steam to produce one barrel of oil.
