Saudi Arabia is the largest supplier of crude oil to India, where oil demand grew by 5.7% last year and is expected by the International Energy Agency to increase 6.3% this year.

"The level of $45-50 (per barrel) is acceptable from the point of view of market balance: if prices go higher shale oil production could start to recover."

Oil-producing countries can come to an agreement capping crude production at January levels even if Iran doesn’t join the move to help shore up prices.

Poorly conceived policies could restrict development of abundant domestic natural gas resources and deny the US energy security, economic, and geopolitical opportunities.

Oil at $35 a barrel is neither too high nor too low but just right to make shares of U.S. explorers worth buying, according to Goldman Sachs Group Inc.

The cumulative effect suggests that for U.S. growth over the next three years, there's no difference between oil at $30 or $70 per barrel. How the trade balance responds to swings in crude will dictate which path is more desirable.

Total capital investment in the oil and natural gas sector is forecast to decline to $31 billion in 2016, down from a record $81 billion in 2014.

State-run Saudi Arabian Oil Co. increased its official selling price for May Light, Medium and Heavy sales to U.S. buyers by 40 cents a barrel, the company said in an e-mailed statement Tuesday. Extra Light crude will sell at a premium of $2.60 a barrel to the regional benchmark, 75 cents higher than the differential in April. For the U.S., the benchmark is the Argus Sour Crude Index.

Front month U.S. West Texas Intermediate (WTI) crude futures were trading at $38.02 per barrel at 0653 GMT, up 76 cents, or 2 percent, from their last close. International Brent futures were up 60 cents at $40.03 a barrel.

Gas shall play a more important role, with more shares in the total Chinese primary energy mix. And, the Chinese natural gas market is at a turning point, as indicated by many experts at Gastech 2015’s conference. The Chinese gas industry is facing many challenges also because of gas demand contraction due to the new normal Chinese economy. In the previous 10-15 years, we had double digit gas demand growth, but in 2014-2015 it was only single digits. Last year it was only 8.6%. This year, in the last 3 quarters, the growth was only 2.7%.
