USGS estimates 53.8 Tcf of natural gas hydrates in Alaska’s North Slope

The Alaska North Slope contains an estimated 53.8 trillion cubic feet of natural gas hydrate resources. As Hurricane Dorian gets closer to Florida, U.S. Geological Survey scientists have been in the field from Savannah. The U.S. Geological Survey has awarded more than $12.5 million to seven universities. Twenty-five middle school girls from Washington and Oregon are participating in the fifth annual GeoGirls. This estimate is for the undiscovered, technically recoverable natural gas resources stored within gas hydrate formations.

Although Tropical Storm Barry is expected to make landfall in Louisiana as a Category 1 hurricane. USGS maps produced since 2002 show that groundwater levels in and near Albuquerque. U.S. Geological Survey field crews are surveying high waters in Iowa to help emergency agencies better respond to future floods. Demonstrating annual benefits of coral reefs including a flood-protection barrier for more than 18,000 coastal citizens. The 17th annual Western South Dakota Hydrology Conference is an opportunity for reporters, scientists, students.

Walter Guidroz, program coordinator says “The USGS is committed to providing the most up-to-date, publicly available”.

As more information becomes available, company sometimes need to revise our assessments. Field crews installed 40 more storm-tide sensors on Florida’s Gulf Coast. The GeoGirls will spend five days conducting hands-on research at Mount St. Helens. The assessment updates a 2008 USGS assessment that estimated about 85 trillion cubic feet of undiscovered. Relatively high groundwater levels in 2016 and reductions in the amount of groundwater-level decline. Technically recoverable gas resources within gas hydrates on the Alaska North Slope.

USGS coastal change experts forecast that wind-driven waves are likely to damage coastal beaches. The USGS has produced maps of drawdown (water-level decline) relative to pre-1961 conditions for the years 2002. The assessment was the first-ever estimate of technically recoverable gas resources within gas hydrate. Barry continues on the course and intensity predicted by the National Hurricane Center on Friday. It is very likely that about one-fifth of sandy beaches in Louisiana and 15 percent of sandy beaches in Mississippi will be overwashed.

The newly released 2018 gas hydrates assessment utilized more extensive 3D seismic mapping. The luncheon keynote speaker is John T. Loucks Distinguished Lecture. It improved data collection and more refined analysis. The 2016 map shows that areas of drawdown are decreasing in spatial extent and magnitude. It access to better maps, as well as greater understanding of gas hydrate reservoir properties. The USGS crews are establishing high-water marks along the Missouri, Little Sioux. The study will help managers take effective actions to reduce the risk to.

It is this refined analysis that yielded a smaller gas volume estimate in the 2018 assessment. High-water marks are visual clues of peak stream height that help verify flood levels recorded. The assessment approach also assumes that the resource can be produced by existing conventional technology. The USGS uses the data to help determine the probability of a similar flood event occurring in the future. The trend of rebounding groundwater levels since 2008 corresponds with decreases in groundwater withdrawals.

The new agreements include work to incorporate real-time GPS observations into ShakeAlert. To date, there is no known commercial production of natural gas from gas hydrate formation. The assumption is based on both limited field testing and numerical production models of gas hydrate-bearing reservoirs. The USGS and its university and nonprofit partners will also further the development of scientific algorithms. No analysis was provided as to whether it would be profitable to produce these resources.

The ABCWUA incorporated the use of surface water from the San Juan-Chama Diversion Project. The information USGS crews are collecting for FEMA is valuable for developing flood risk maps. Gas hydrates are naturally occurring, ice-like solids in which water molecules trap gas molecules in a cage-like structure. It determining potential impacts of floods on people and infrastructure. It highlights the important role that coral reefs play not only for coastal communities in the U.S. mainland. It will camp hike to field sites, work on research projects with scientists.

They are only stable within a narrow range of temperatures and pressures and are usually found in seafloor sediments. The research results will be of great interest to the U.S. Coral Reef Task Force. Although many gases form hydrates in nature, methane hydrate is by far the most common. Members of the news media are invited to observe research activities. The high-water mark data will help FEMA prioritize claims for assistance programs in local communities. USGS science can help save lives, minimize property damage and reduce risks from natural hazards.

USGS scientist Tim Collett says “The study of gas hydrate as an energy resource is still an emerging field”.

The USGS Gas Hydrates Project conducts multidisciplinary field studies. Most of the instruments are designed to measure the height and duration of the storm-tide. Sensor networks will be upgraded and new seismic stations will be installed to improve the speed and reliability of the warnings. In many areas of the world, groundwater levels are dropping due to pumping. There are about 200 USGS-operated streamgages in Iowa that measure water levels, streamflow and rainfall. In addition to the Alaska North Slope research, company have been participating in.

The Gas Hydrates Project provides unique capabilities and special high-pressure laboratory facilities. The information is routinely used for water supply and management, monitoring floods. It producing the first assessment of technically recoverable gas hydrate resources. The USGS Science in Iowa Twitter and Facebook pages are being updated with photos. It characterizing the physical properties of hydrate-bearing sediments to constrain reservoir properties. The ShakeAlert partners will also continue user training and education efforts.

The USGS has been conducting research on gas hydrates since the 1980s. Other water conservation efforts also account for rising groundwater levels. It also help develop flood prediction tools for future mitigation efforts. The USGS has studied the resource potential of gas hydrates for more than 35 years. In Georgia, field scientists are installing 50 storm-tide sensors the length of the state’s low-lying coastline. Company acquiring data to image the distribution of these deposits on the U.S. Atlantic, Gulf of Mexico.
