Around the same time, several cities in the Eastern United States established primitive streamgages to help design water-supply systems. Streamgaging technology has greatly advanced since the 1800s, and USGS hydrographers have made at least one streamflow measurement at more than 37,000 sites throughout the years. Today, the USGS Groundwater and Streamflow Information Program supports the collection and (or) delivery of both streamflow and water-level information for more than 8,500 sites (continuous or partial record) and water-level information alone for more than 1,700 additional sites. The data are served online—most in near realtime—to meet many diverse needs; more than 640 million requests for streamflow information were fulfilled during the 2017 water year (October 1, 2016‒ September 30, 2017).","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":"69284137","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}

These include an assessment of tight-oil resources in the lower Permian Lucaogou Formation (Yang and others, 2010) of the Santanghu Basin (Altay-Sayan Folded Region Province) and tight gas in the Lower Jurassic Badaowan Formation (Guo and others, 2014; Yang and others, 2015) in the southern part of the Junggar Basin (Junggar Basin Province) (fig. 1). Lacustrine mudstones of the Lucaogou Formation are present in several basins and intervening uplifts in northwestern China (Carroll and Wartes, 2003). Tight oil is produced from this formation in the Junggar Basin, and in 2016, the USGS completed an assessment of tight-oil and tight-gas resources in the Lucaogou of the Junggar Basin (Potter and others, 2017). Over the past 15 years in the Santanghu Basin, oil has been discovered and produced from several types of tight reservoirs in the Lucaogou Formation; this oil has apparently undergone short-distance vertical migration from interbedded organic-rich mudstone (Hackley and others, 2016). The thick Lower Jurassic Badaowan Formation in the southern Junggar Basin represents a fluvial and shallow lacustrine system containing low-permeability channel sandstones interbedded with coal and carbonaceous shale. Guo and others (2014) indicate that the tight sandstone layers and lenses contain a significant gas resource sourced mainly from the coals—a geologic framework that is very similar to that of major tight-gas fields in the western United States. In the southern Junggar Basin, natural gas has been discovered in coal and shale within the Badaowan (Petromin Resources, 2009); possible resource exploration concepts include tight gas, shale gas, and coalbed gas (Guo and others, 2014). This 2018 USGS assessment focused on tight-gas resources in sandstone that are analogous to tight-gas sandstones in the Upper Cretaceous Mesaverde Group in the Piceance Basin, Colorado (Johnson and Roberts, 2003; Cumella, 2009).","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":"69284246","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}

Previous USGS oil and gas assessments in this basin include a 2015 shale-gas assessment in three Paleozoic stratigraphic intervals in the Sichuan Basin (Potter and others, 2015; Potter, 2018) and a 2012 assessment of conventional oil and gas resources in six major Chinese basins (Charpentier and others, 2012). Chinese national oil companies currently produce tight gas from the Xujiahe (Zhao, Bian, and others, 2013) and tight oil from the Da’anzhai and Lianggaoshan (Chen and others, 2015; Yang and others, 2016) in the central part of the Sichuan Basin. The Xujiahe is a thick fluvial unit that includes three widely distributed coaly gas-prone (Type III) source intervals, each generally 50–150 meters (m) thick and containing numerous coal beds that are a few meters thick (Zou, Tao, and others, 2009; Zhu and others, 2012). These source intervals are alternately stacked with three low-permeability sand reservoir intervals (up to 40 m thick with individual sand reservoirs 3–8 m thick) (Zou, Tao, and others, 2009; Zhao, Bian, and others, 2013; Zou, Gong, and others, 2013). The Da’anzhai and Lianggaoshan contain lacustrine black shales that are rich in Type I and II (oil-prone) organic matter (Li and others, 2014) and are interbedded with tight reservoir units that include a shelly limestone (Da’anzhai) and a sandstone (Lianggaoshan) (Yang and others, 2016). The Da’anzhai is 0–60 m thick, and the Lianggaoshan is 0–100 m thick (Yang and others, 2016).","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":"69284234","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}

The Mesoproterozoic Roper Group in the basin contains the Velkerri and Kyalla Formations, two organic-rich source formations that possibly form some of the oldest viable petroleum systems in the world (Jackson and others, 1986; Silverman and Ahlbrandt, 2011; Cox and others, 2016). The shale units of the Velkerri and Kyalla were deposited between 1,400 and 1,300 million years ago (Yang and others, 2018). Limited drilling and production testing have shown that these rocks may contain recoverable oil and gas resources (Close, Cote, and others, 2017). For rocks of this age to potentially contain recoverable oil and gas indicates that throughout the long period between the Mesoproterozoic and the present, there has been limited deformation of the Beetaloo Basin, and generation might have been relatively late in the burial history. However, the tectonic evolution of the Mesoproterozoic Beetaloo Basin is largely unknown, and several hypotheses have been advanced that include rift basin, multiphase intracontinental basin, foreland basin, and epicontinental basin development (Silverman and Ahlbrandt, 2011; Cox and others, 2016; Close, Cote, and others, 2017; Yang and others, 2018).
