South Dakota School of Mines & Technology, USA
Time : 9:45-10:30
Daniel J. Soeder is director of the Energy Resources Initiative at South Dakota School of Mines & Technology in Rapid City, SD, USA. He joined SD Mines in May 2017 with eight years of experience as a research scientist at the Morgantown, WV campus of the U.S. Department of Energy (DOE) National Energy Technology Laboratory, where he investigated the environmental risks of unconventional oil and gas development, and 18 years as a hydrologist with the U.S. Geological Survey (USGS) studying groundwater contamination on the U.S. east coast, and nuclear waste isolation in Nevada. Prior to joining the USGS, he spent a decade with the Gas Technology Institute in Chicago, researching hydrocarbon production from unconventional resources. He also worked as a DOE contractor collecting and characterizing Eastern Gas Shale Project cores. He holds a BS from Cleveland State University, and an MS from Bowling Green State University (Ohio), both in geology
The hydrocarbon resources of shale gas and tight oil have made a significant impact on North American energy supplies over the past decade. The production of so-called “unconventional” natural gas from U.S and Canadian shales has saturated North American gas markets, boosted Canada’s exports, and turned the U.S. into a net exporter of natural gas. Tight oil from the Bakken Shale has made North Dakota the second largest oil-producing state in the U.S., trailing only Texas, which maintains first place because of equally prolific liquids production from the Eagle Ford Shale and multiple shales in the Permian basin. Shale development blossomed in the United States between 2005 and 2010, driven by high energy prices, favorable lease positions, and the availability of technology that could economically produce commercial quantities of hydrocarbons from these formations. Development in Canada began later, and some shales have also been developed in Mexico. It is difficult to overstate the importance of shale gas and oil resources to the U.S. and North American energy economies.
Because U.S. unconventional oil and gas achieved dominance in less than a decade, it appears to many people that it came out of nowhere. In reality, researchers and industry went through an intense and protracted technical struggle. Modern attempts to assess and produce these resources began in the late 1970s, but success was elusive for nearly two decades until some visionary people hit upon the combination of horizontal drilling and staged hydraulic fracturing that proved to be a successful technology for producing shale gas and tight oil reservoirs. Shale development creates environmental risks to air and water, and technology that works on one shale play may not work on another. Other countries are looking to North American for leadership on environmental and developmental challenges as they consider producing their own shale resources.

Keynote: Conversion of methane gas from coal and oil and gas sources as a stop gap for the electrical grid and reduction in climate change gases
Time : 10:30-11:15
Dr. Steven Tedesco has thirty-four years of experience in the resource business involving all aspects of petroleum exploration and production with additional experiences in coal and precious metal mining, ranching and farming. Dr.Tedesco is a high achiever who has a history of successful business management and money raising and is looking to serve on the board for a company with the right assets, vision and organization.
Because of growing concerns about climate change and methane emissions, US and Canadian federal, state and provincial governments are addressing how to remove methane gas from the atmosphere in an economical way. Methane is generated from a variety of industrial, geologic and biological sources but specifically discussed here are stranded or shut-in gas wells, well flaring, coal mine leakage and coal bed methane well sources. In the US in 2016 $201 BCFG was flared or vented with an economic loss of $522M+. In conjunction with this problem is the decommissioning of significant numbers of coal-fired and nuclear power plants in the US and Canada. The trend is toward more power plants driven by natural gas and renewable sources excluding hydro. Governmental and industry concern is that the decommissioning of power plants with a capacity of 72GW will not be replaced as quickly as needed by natural gas and renewable sources. In addition, many states in 2018 will be enact significant fines for flaring and leaking oil and gas industry facilities that do not cease methane emission and achieve zero emissions. The equipment to process non-marketable or secondary gas has been around for some time. However, simply converting this gas to electricity still creates significant emissions. The goal of several states is to create zero emissions for which the technology does exist and is an additional add on. In addition, converting gas to electricity and selling it to the grid today is more easily done in many oil, gas and coal areas then historically. A specific need for electricity is the Internet industry which has projected electrical demand for “server farms” or “data centers” for data mining to require 50 power plants at 500 megawatts each by 2020. These “server farms” require tremendous amount of electricity to cool and heat the facilities year round which will cause distress in the electric grid in the US and Canada. If all of the “server farms” were combined worldwide they would be equivalent to a country consumption between Italy and Spain. The application of this technology is worldwide. As governments and regulators seek to eliminate natural gas emissions from both natural gas wells, factories and biomass sites the need for technology will grow. As the world economy grows the need for sources of electricity will be benefited by this technology. The opportunity for the coal, oil and gas industry is clearly present in converting stranded, flared and abandon gas wells into profit centers and minimize negative public view point of these type of operations.

Research Institute of Petroleum Exploration and Development, China
Time : 12:15-13:00
Professor Jia is an expert of development of natural gas resource. He received his B.S. degree in Petroleum Geology from the China University of Petroleum and his M.S. and Ph.D. degrees in Petroleum Engineering from Research Institute of Petroleum Exploration & Development (RIPED), Beijing, China. In 2005 he became a Professor of Petroleum Engineering at RIPED, PetroChina. From 1992, he has worked in the areas of oil & gas geology, reservoir modeling and engineering. He is currently director of Ordos Basin Branch Institute of RIPED, PetroChina. As a professor, he has published over 80 papers and 10 books in the oil & gas development fields.
Tight gas plays an important role in natural gas of China. After about 15 years exploration and development, the original reserves and explored reserves of tight gas have been proven to be in large scale. It has fulfilled the beneficially development in Ordos Basin, Sichuan Basin and Songliao Basin, and the total production has exceeded 30 billion cubic meters, accounting for about 1/4 of total natural gas production of China.
In this paper, geological characteristics of China's tight gas reservoirs are systematically analyzed, which are divided into three kinds: multi-layered stacked lenticular reservoir, layered reservoir and massive reservoir. Meanwhile, it`s more complicated for tight gas development in China than that in the United States or in Canada through the comparison of reservoir geological characteristics.
The tight gas development is benefit from engineering and technology based on its own geological characteristics, including high-quality reservoir prediction and well placement optimization, low-cost & fast drilling technology, large well group-multiply well group-factory operating pattern drilling technology, stimulation technology, underground restriction & low pressure transmission, water drainage technique and digital management.
Though tight gas develops fast, it faces with the general problem of low recovery at the same time, with the value just around 35%. Therefore, enhance gas recovery rate has become the key issue now and the future. Taking Sulige gas field, the largest natural gas field in China for example, four kinds of technical methods, reasonable allocation of well production, water drainage technique, old well lateral drilling and well pattern infilling, are introduced to increase gas recovery efficiency. The series of techniques can also provide reference for the same kinds of reservoirs to guarantee stable and beneficial development in the long term.
