Report: Alaska pipeline not on long-term projects (AP)

JUNEAU, Alaska – Federal analysts believe will not be cost-effective to build a major natural gas pipeline in Alaska for the next 20 years, at least according to a report recently by the energy information administration of the USA.

Study finds domestic energy markets through 2035, high construction costs for rates and lower natural gas wellhead, in terms of 2009, like making a line still during this time. The report represents what Benneche Agency analyst calls its "best of Joe guess what is likely to result."

Two of the pipeline, the Alberta Canada, based on the TransCanada Corp., gas pipeline of Alaska Denali-The, they pursue proposals to bring gas from the North of Alaska to markets in North America or overseas 2020. Cost estimates for different options have ranged from 20 billion 41 billion for a long time to expand into Canada.

TransCanada is ExxonMobil Corp. promote line and up to 500 million in support from doing this as part of signature .Gov. then Sarah Palin Alaska Gasline Inducement Act. Denali working with BP and ConocoPhillips.

Benneche said Wednesday projections call the average price in the lower 48 wellhead to improve the point at which the project financial sense around 2033. After construction, the line can be serviced by 2036 or 2037, he said.

"It's not like we took it" image total energy, Benneche said.

For years, Alaskans have hoped for a pipeline as a way to help shore up revenue from oil production rejects, create jobs and provide a more reliable source of energy. .Gov. light Parnell has expressed optimism the chances of a line, given that they are all now TransCanada Vdnali negotiating with gas producers, and are designed to secure the delivery obligations.

Widely believed a same only one pipeline, if one opens the rule. Officials said their consider factors such as long term gas prices, provide tax rates predictions in evaluating moving forward.

The decision is going to be "up to the companies," said Larry Persily, manages federal natural gas pipeline projects to Alaska.

He said that the report does not worry or overwhelm it. For example, its sales projections do not include proposed changes to federal law or regulations governing, for example, gas shale gas can produce on-demand, create more impressive, Alaska gas Persily said.

A team of Alaska gas line believes that a separate report to the State Commission on outlook gas development project "support of the gas line," said Marc Morones, program manager of the Alaska Gasline Inducement Act.

TransCanada spokesman did not immediately return a call Wednesday. Dover Denali was out of the Office.

North Slope spill focuses on flow lines (AP) report

Anchorage, Alaska - a new status report on Alaska North Slope oil leaks comes to the conclusion that the flow lines, moving of crude oil, water and natural gas from well to establishments require increased monitoring.

The report by the State Department of environmental conservation revised extracted aging infrastructure and process oil, which moves finally through the Trans Alaska pipeline unloaded its first barrel in port Valdez in 1977.

Federal regulators to monitor the Trans Alaska pipeline and other crude oil lines on the north slope. The State monitoring flow lines.

The State report was ordered by the Alaska to large overflow in 2006. One was in a State-controlled oil line leading from a processing plant.

Larry Dietrick State spill response Director, said on Thursday, the report dripping hundreds of spill reports from pinhole on leaks from more than 10,000 gallons, checks with a view to predicting future events.

The study covered hundreds of miles of pipeline in the massive oil fields, processing centers and storage tanks all components in the system-. The No. 1 culprit for leaks are said valve seals.

"But our large spill problems are all flow lines," he said because of the potential for a large spill.

Some of the flow line pipes are great - as much as 24 inches in diameter, said Dietrick. Enter the most corrosive materials on the slopes, he said the three way combination of oil, gas and water. And unlike a crude oil pipeline, the implementation of a single fluid you cannot watch for leaks 24 hours a day by a machine.

"They have an automated leak detection," he said. "Due to not run right the three phases flow meters get."

Instead you are manually checked but if an inspector only once every three days could have eyeballs you two days of spillage you before a leak is detected, he said.

Corrosion is a common cause of leaks and external corrosion was the most common cause of the failure flow lines.

The report did not detect that changes in the number of spills per year but proposed that the frequency of spills has increased more than 1,000 gallons.

The report with industry, such as fire or gas leaks not assess other risks.

The DEC is a conference sponsor examine advances in leak detection technology. The results are calculated for potential new leak detection regulations for flow lines.

DEC works sanctions for spills with the Department of law, whether statutes require update to examine.

It is a challenge for the industry and regulators alike for how to change the terms in the oil fields keep Dietrick said. If sediment in rows was created, so you can corrosion by microbes, which in the sediments of life.

The industry uses more that 2 million gallons of protective equipment per year.

"The problem is not that there is no program,", he said. "It's a challenge to keep the programs calibrated to the changing conditions."
