The International Energy Agency estimates that over $25 trillion of investment will be needed in oil and gas supply alone from 2015 to 2040. So the long-term investment case for oil and gas remains strong, despite the fall in oil prices over the last 18 months. The concern is that prices seen in late 2015 and early 2016 may be too low to spur investment in projects that are needed to ensure long-term supplies. Without sufficient investment, the risk of demand exceeding supply will increase.

Brent crude oil prices are forecast to average $34/b in 2016 and $40/b in 2017, $3/b and $10/b lower than forecast in last month's STEO, respectively. The lower forecast prices reflect oil production that has been more resilient than expected in a low-price environment and lower expectations for forecast oil demand growth.

U.S. monthly crude oil production in December 2015 continued to decline, as oil production reached its lowest level since November 2014. Production also declined from year-ago levels for the first time in more than four years. This continued production decline is the result of lower crude prices, which have declined more than 70% since the summer of 2014.

“Despite some mitigating factors, lower oil prices are, on the whole, not favorable for Canada,” the study says, suggesting, “For every Canadian-dollar gain in WTI price, Canadian GDP would gain almost $1.7 billion on average.”

Petroleum exploration activity in Australia has collapsed in the wake of the plunge in global oil prices over the last 18 months, a period in which the country's crude production has fallen to its lowest level in 45 years, according to a report released Wednesday at an industry conference in Sydney.

Brent crude futures LCOc1 were at $40.88 per barrel at 0339 GMT, down 19 cents from their last close.

Oil prices fell on Tuesday on weak Chinese trading data, but Brent remained over $40 a barrel after jumping to 2016 highs the previous day when producers announced talks to support the market and investors opened new bullish bets.

Global crude markets will see a correction before the end of this year as current prices are forcing all producers to freeze their production, the United Arab Emirates’ energy minister Suhail bin Mohammed al-Mazrouei said Monday.

China's crude oil imports in February rose 20.2 percent on a daily basis compared to same month last year, reaching a new record, official customs data showed on Tuesday.

Indian oil demand, meanwhile, grew by 300,000 b/d last year after rising by 100,000-150,000 b/d/year in the previous decade.
