Gift of Gas Storage Field Data

Borehole Mt. Simon

Ed Mehnert, Illinois State Geological Survey geologist, received four boxes of geological, geochemical, and geophysical data from Karen Benson, Vice President of Operations Services and Underground Storage, Southern Pipeline Group. The data were collected from 26 boreholes completed in the Trenton limestone and Mt. Simon Sandstone at the Tuscola natural gas field (Champaign and Douglas counties), which ceased operations in the 1990s. The data include an aquifer test, core descriptions, laboratory core tests (porosity and permeability), borehole logs, and water quality. These data will be very valuable for our efforts to understand geologic carbon sequestration in the Mt. Simon Sandstone. Mehnert is extremely grateful to Karen Benson and her company for locating and donating these geologic records, which were preseumably lost after the Tuscola natural gas storage field ceased operations
