They have to pipe seawater hundreds of miles and then pump it up to several thousand psi. Pretty power intensive.

Thanks, Nate for your excellent article!

"The age of easy oil is over" says Schlumberger chief executive Andrew Gould. How much longer do we have to wait until Zergin and Zillerson make similar statements?

Global oil and gas investment 'insufficient'

By Upstream staff

Investment in new oil and gas projects is not enough to boost needed global energy capacity, Schlumberger chief executive Andrew Gould today.

Gould told investment bank Howard Weil's annual energy conference that low investment and project delays, as well as rapid decline in existing fields were slowing the growth of energy capacity worldwide, MarketWatch reported.

"Supply response to create a cushion of spare production capacity will take longer than we originally thought," Gould said.

He said that while producers were coming to terms with higher costs, spare capacity remained below historical levels. He said only a recession could bring short-term relief to the situation by temprarily slowing demand.

"The age of easy oil is over," he said.

Nevertheless, Gould said he expected demand for the oilfield services offered by his company to increase over the next few years.

Schlumberger is the world's largest oilfield services company.
