Suncor Energy Inc. has reported a second-quarter net loss of $614 million after it cut back on production to deal with sharply reduced crude prices amid lower global energy demand. Suncor's total production was 18.5% less than the 803,900 boe/d in the prior-year quarter, as it took measures including shutting down one of the two production trains at its Fort Hills oilsands mine in northern Alberta.
