The deal will give Calgary-based TransCanada a strategic position in the Marcellus and Utica shales of Pennsylvania, Ohio and West Virginia, the most promising regions in the US for gas production growth.

U.S. Rig Count is down 4 rigs from last week to 476, with oil rigs up 1 to 387, and gas rigs down 5 to 89. Canadian Rig Count is down 29 rigs from last week to 69, with oil rigs down 16 to 12, and gas rigs down 13 to 57.

Analysts estimate that between 15 and 20 percent of 2016 U.S. oil production is hedged, and as little as 2 percent for 2017.

Looking at the outcome of the sensitivities Mr Tomnay offers in closing: “Russia's export strategy will be a key determinant of US LNG export capacity utilisation, but the Russian pursuit of European market share to drive out US LNG from Europe seems either uneconomic and/or impractical under different external conditions. Instead other factors such as the price of US gas, oil and European coal prices will likely be greater determinants of US LNG export capacity utilisation. Subject to these factors alone, average utilisation of US LNG export capacity between 2017-20 could vary from 54-100%. For US LNG exporters, the best thing to happen would be for global coal prices to rise, or for US gas prices to stay low."

U.S. companies are welcome to invest in Iran's oil and gas industry, the Iranian oil minister said.

This is American energy security, American jobs, U.S. government revenue and American GDP tied up by political red tape. This is a once in a generation opportunity, stuck, off limits to future generations as it waits for forward-looking energy policy.

Additional regulations on methane by the administration could discourage the shale energy revolution that has helped America lead the world in reducing emissions while significantly lowering the costs of energy to consumers. The administration is catering to environmental extremists at the expense of American consumers.

Oil prices have rallied by almost 50 per cent since dropping below $30 a barrel in January, tempting producers to grab any price that will allow them to keep operating through the worst commodity crash in more than 20 years.

U.S. Rig Count is down 9 rigs from last week to 480, with oil rigs down 6 to 386, and gas rigs down 3 to 94. Canadian Rig Count is down 31 rigs from last week to 98, with oil rigs down 22 to 28, and gas rigs down 9 to 70.

At low oil prices, customer choice rather than strategic Russian decision-making would allow Russia to retain over 30% of the roughly 490bn m³/yr European market and threaten US LNG export volumes.
