These strata are the principal source rocks for conventional oil and gas fields in the interior of the Tarim Basin (Li and others 2018; Zhu, Chen, and others, 2018). The Tarim Basin, the largest petroleum basin in China, encompasses 563,000 square kilometers (km), and its Phanerozoic strata are as much as 16 km thick (Qiu and others, 2012). Although numerous oil and gas fields have been developed along its northern margin and in several uplifts in the basin’s interior, large parts of this remote basin remain unexplored. The USGS previously assessed the Tarim Basin’s conventional oil and gas resources (Charpentier and others, 2012). Paleozoic marine formations are currently preserved at depth and locally exposed around the basin’s periphery. They were deposited on the passive margin of the Tarim craton, a continental fragment proximal to the Gondwana margin. Since the late Paleozoic assembly of Central Asia, the Tarim Basin has been a vast nonmarine basin bounded on the south by the Tibetan Plateau and on the north by the Tien Shan. From the Carboniferous to the present, the basin’s margins have been strongly influenced by contractional deformation, including the ongoing Himalayan orogeny. This tectonic history has resulted in a relatively cool geothermal setting throughout the basin’s history; the current geothermal gradient is in the range of 20–23 degrees Celsius per km (Zhang, Huang, and others, 2015).

The basin is asymmetric with a steeply dipping, structurally complex northeastern margin associated with a sedimentary section that gradually thins and shallows to the southwest. Silurian and Devonian organic-rich shales are the major petroleum source rocks in the basin (Boote and others, 1998). Organic matter in both source rocks may have reached the thermal generation window for oil during Carboniferous burial; both source rock intervals reached the gas-generation window during the Late Triassic–Jurassic (Boote and others, 1998; Logan and Duddy, 1998; Makhous and Galushkin, 2003; Zuehlke and others, 2010; Jaeger and others, 2017).

The Phosphoria Formation represents a complex stratigraphic unit that was deposited in an oceanic embayment along the west-facing Permian continental margin (Sheldon, 1963). During Guadalupian time, cold, nutrient-rich currents from the north swept the embayment, resulting in deposition of phosphatic mudstone, organic-rich shale, and chert in what was otherwise a sediment-starved basin (Piper and Medrano, 1994; Carroll and others, 1998). The deepwater lithologies of the basin transition eastward to shallow-water shelf carbonates of the Permian Park City Formation and finally to continental red mudstone and evaporites of the Permian Goose Egg Formation. Much of the area with the deepwater facies of the Phosphoria Formation is within the Wyoming Thrust Belt Province, but there are deepwater deposits in which the Phosphoria Formation is as much as 10,000 meters (m) deep in the western part of the Southwest Wyoming Province. The purpose of this assessment is to estimate technically recoverable shale-gas resources within Phosphoria Formation shales.","PeriodicalId":36286,"journal":{"name":"U.S. Geological Survey Fact Sheet","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69284805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Droughts can reduce the water available for societal needs, such as public and private drinking-water supplies, farming, and industry, and for ecological health, such as maintenance of water quality and natural ecosystems. Recent droughts in the northeastern United States have highlighted the need for new scientific tools to forecast the probability of future droughts so water managers and the public can be better prepared for these events when they happen. Two recent U.S. Geological Survey (USGS) studies provide tools that can forecast the probabilities of summer droughts for streams (Austin and Nelms, 2017) and the probabilities of groundwaterlevel declines below specified targets or thresholds (Dudley and others, 2017). These tools provide promising methods for identifying and anticipating probable streamflow and groundwater droughts specific to the northeastern United States. USGS Water Science Centers in the northeastern United States have acted together to use these methods for numerous streamflow gages and groundwater-level monitoring wells, and to make the results of the analyses available on the world wide web. This fact sheet describes the drought forecasting techniques used in a study to predict droughts for streamflow and groundwater in the northeastern United States.","PeriodicalId":36286,"journal":{"name":"U.S. Geological Survey Fact Sheet","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69284311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
