Oil, Gas and Solution Mining Technical Presentations
This page makes available recent formal and information presentations by staff of DEC's Oil, Gas and Solution Salt Mining regulatory program.
DEC geologists and engineers within the Division of Mineral Resources both teach and learn from other professionals in their fields. Staff maintain contact with other government agencies and industry organizations whose focus is on oil and gas wells, solution salt mining and underground gas storage. This exchange of information occurs chiefly through professsional publications and professional conferences and meetings.

- Stratigraphic Section, SW New York State - A large table describing a stratigraphic section from Southwest New York State.
- 25 Years of Gas Production - A statistical evaluation of twenty-five years of gas production in New York State with production broken-out by producing field and formation.
- Trenton Exploration and Development - Exploration and development of the Late Ordovician Trenton Limestone has occurred in New York State since the late 1800s. From the early days of exploration to the present, the Trenton has proven to be an elusive target for developers. NYSDEC Division of Mineral Resources.
- Northern Appalachian Basin Gas Mixing - Stable isotopic studies were undertaken to investigate the origin of 20 oil-associated and non-associated gases from western and central New York State in the northern Appalachian basin.
- Ins and Outs of Solution Salt Mining - The salt mining industry has prospered in New York State since 1878 when commercial quantities of subsurface rock salt were inadvertently discovered at a well drilled for oil and gas. NYSDEC Division of Mineral Resources.
- Development of Solution Salt Mining Regulation - New York's current solution mining regulatory program was founded in 1973 when the oil and gas law was amended to include solution mining wells. Prior to this legislation, the scope of state knowledge regarding solution mining facilities was extremely limited. State involvement in review and approval of well drilling and plugging proposals increased after 1973, but cavern development operations and well abandonments continued to occur with little state oversight. At the end of 1973, there were 250 unplugged solution mining wells at six facilities, including five active operations and one shut down in 1962. No more than 60 wells were in use, leaving at least 190 that had been abandoned but not plugged. By 1973, five sinkholes had formed in the Tully Valley brine field in Onondaga County, where 156 abandoned wells were located. Regulated by the NYSDEC Division of Mineral Resources.
- Solution Salt Mining in New York - Bedded subsurface salt was first solution mined in New York in a well drilled for oil or gas in Wyoming County in 1878. The salt occurs in the Silurian Syracuse and Vernon formations at depths of 500 to 4000 feet, with a net aggregate salt thickness of up to 800 feet. NYSDEC Division of Mineral Resources.
- Solution Salt Mining in Tully Valley - Five solution mining facilities in New York produce over two billion gallons of saturated brine, or over 1.7 million short tons of salt, per year. Operators of these facilities had drilled 287 wells by the end of 1995. They use the techniques of hydrofracturing, horizontal drilling, and roof padding to develop stable caverns.

- Ups and Downs of the Tully Valley Brine Field - A formal subsidence monitoring program for the brine field was instituted by Allied Chemical Company in 1959 and continued until1991. A post-closure subsidence monitoring program, required by the State in conjunction with the well plugging agreement, started in 1993. Results to date have been both unexpected and interesting.
