A TECHNICAL WORKSHOP
“Appalachian Storage Hub for Natural Gas Liquids”
August 29, 2017, Hilton Garden Inn Southpointe, Canonsburg, PA
Check-in opens: 8:00 a.m.
Workshop: 9:00 a.m. to 5:00 p.m.
The first public release of results from a one-year, regional geologic study
State officials in Ohio, Pennsylvania, and West Virginia are promoting a high-technology program to enhance economic development by expanding the market for ethane and other natural gas liquids (NGLs) production from the liquids-rich Marcellus and Utica shale plays. The vision is to create a robust infrastructure supporting the creation of value from the prolific NGLs production in the Appalachian Basin, including NGLs storage and trading plus pipeline infrastructure.
The Tri-State Shale Coalition (see box) realized that a critical first step in the development of infrastructure and expanded industrial growth would be to conduct a geologic investigation of the potential to develop adequate subsurface storage along the pipeline route. Such a study would provide data essential to decision-makers intent on supporting the development of an Appalachian Storage Hub and the petrochemical industry.
The Appalachian Oil and Natural Gas Research Consortium (AONGRC), a program of the WVU Energy Institute’s National Research Center for Coal and Energy, was tasked with evaluating the storage potential of subsurface stratigraphic units along the pipeline route. Individual formations and intervals of interest include the Greenbrier Limestone for subsurface mining; the Salina salt for the creation of cavities through brine extraction; and depleted gas fields and gas storage fields in sandstone reservoirs in the Lower Mississippian (Keener to Berea Interval); Upper Devonian (Venango, Bradford and Elk Intervals), Lower Devonian (Oriskany Sandstone); Upper Silurian (Newburg sandstone); Lower Silurian (Clinton/Medina Group); and Lower Ordovician (Rose Run Formation) – Upper Cambrian (Gatesburg Formation).
- The goal of the study was to complete a geologic study of all potential options for subsurface storage of liquid ethane and other NGLs along and adjacent to the Ohio River from southwest Pennsylvania to eastern Kentucky, with a similar study along the Kanawha River in West Virginia. This involved the mapping and identification of areas where the Salina F Salt is at least 100 feet thick and suitable for solution mining; mapping and identification of areas of the Greenbrier Limestone that are at least 40 feet thick and suitable for hard-rock mining; and mapping the thickness and extent of sandstone reservoirs in depleted gas fields that could be converted to NGLs storage.
- The study was completed July 31, 2017, and produced three main products: (1) a regional subsurface geologic investigation of all geologic units of interest; (2) a detailed reservoir characterization effort, including field-level studies, rating criteria used to screen candidate fields, the final ranking of storage candidates and presentation of three prospect areas; and (3) the publicly accessible website in which all of the above reside. These deliverables are intended to guide the future site investigations conducted by any operators interested in developing the Appalachian Storage Hub.
During this technical workshop, members of the Research Team will present the research that was conducted, areas that “graded” the highest for subsurface storage of NGLs, and recommendations for the next phase of subsurface research prior to creating the Appalachian Storage Hub.
Who Should attend
This course will present the results, conclusions, and recommendations in the Appalachian Storage Hub Final Report, and should be attended by geologists, engineers, regulatory agency personnel and anyone who has an interest in developing a subsurface storage facility for NGLs in the Appalachian basin to take advantage of the wet natural gas resources in the Marcellus and Utica shale plays.
By the end of this course, participants will have an understanding of:
- The contents and organization of, and public access to, the Appalachian Storage Hub project database
- Regional subsurface geology of 10 formations or stratigraphic intervals considered to be candidates for subsurface storage
- Reservoir character of candidate reservoirs
- Criteria to evaluate and rank three types of storage containers
- Ranking results for mined-limestone and solution-mined salt cavities and depleted gas reservoirs
- Stacked opportunities and evaluation of field-level prospects
- Recommendations for follow-up site-specific geologic and engineering studies
