USGS estimates 2.4 Tcf of gas lies beneath eastern Oregon, Washington

An estimated 2.4 trillion cubic feet of natural gas and 9.8 million bbl of natural gas liquids lie beneath eastern Oregon and Washington, the US Geological Survey said in late October.

The figures are mean estimates of undiscovered gas resources beneath approximately 60,000 square miles of the two Pacific Northwest states. A USGS team conducted a geology-based assessment using the total petroleum system approach, the US Department of the Interior agency said. The work was done in 2006 but specific figures were not released until recently, a spokeswoman said.

The report said that the Columbia River Basalt Group, ranging from 4,000 to 18,000 feet in thickness, overlies the Cretaceous Tertiary TPS in the area east of the Cascade Mountains. Volcanic rock units from the Miocene epoch through the Quaternary period overlie overlying the province's most southern part previously limited knowledge of that area's stratigraphy and structural geology, USGS said.

Within the hypothetical Columbia Basin Assessment Unit, which covers more than 4 million acres, the assessment team estimated that 2.1 Tcf of gas and 9.2 million bbl of NGLs are in Tertiary rocks beneath the Columbia River Basalt, according to the report. The largest undiscovered gas field within the AU holds a mean estimate of 362.9 billion cubic feet, it added.

In a second area, the hypothetical Eastern Oregon and Washington Conventional Gas AU covering more than 22.2 million acres, the report listed a mean estimate of 300 Bcf of conventional gas and 610,000 bbl of NGLs. It said that the estimated mean size of the AU's largest undiscovered gas field is 78.3 Bcf.

The report said that the assessment team identified a third area, the Republican Graben Gas AU, but did not quantitatively assess it.

It said that some 5,000-10,000 feet of arkosic sandstone, mudstone, lacustrine shale and coal which include potential source and reservoir rocks are known to be present beneath the basalt of North-Central Oregon and Central Washington. It indicated that the province's only discovered commercial gas accumulation is the abandoned Rattlesnake Hills gas field, which produced approximately 1.3 Bcf.

"Numerous other gas shows are known within the province but as of 2006, there have been no new commercial accumulations found," the report said.

Global LNG: Adjusting to New Realities

Fri, Mar 20, 2015

Oil & Gas Journal’s March 20, 2015, webcast will look at how global LNG trade will be affected over the next 12-24 months by falling crude oil prices and changing patterns and pressures of demand. Will US LNG production play a role in balancing markets? Or will it add to a growing global oversupply of LNG for markets remote from easier natural gas supply? Will new buyers with marginal credit, smaller requirements, or great need for flexibility begin to look attractive to suppliers? How will high-cost, mega-projects in Australia respond to new construction cost trends?

US Midstream at a Crossroads

Fri, Mar 6, 2015

Oil & Gas Journal’s Mar. 6, 2015, webcast will focus on US midstream companies at an inflection point in their development in response to more than 6 years shale oil and gas production growth. Major infrastructure—gas plants, gathering systems, and takeaway pipelines—have been built. Major fractionation hubs have expanded. Given the radically changed pricing environment since mid-2014, where do processors go from here? What is the fate of large projects caught in mid-development? How to producers and processors cooperate to ensure a sustainable and profitable future? This event will serve to set the discussion table for the annual GPA Convention in San Antonio, Apr. 13-16, 2015.

This event is sponsored by Leidos Engineering.

The Future of US Refining

Fri, Feb 6, 2015

Oil & Gas Journal’s Feb. 6, 2015, webcast will focus on the future of US refining as various forces this year conspire to pull the industry in different directions. Lower oil prices generally reduce feedstock costs, but they have also lowered refiners’ returns, as 2015 begins with refined products priced at lows not seen in years. If lower per-barrel crude prices dampen production of lighter crudes among shale plays, what will happen to refiners’ plans to export more barrels of lighter crudes? And as always, refiners will be affected by government regulations, particularly those that suppress demand, increase costs, or limit access to markets or supply.
