RI4 Possibilities for the Storage of Natural Gas in Delaware

RI4 Possibilities for the Storage of Natural Gas in Delaware

Considerable quantities of natural gas are used in Delaware; however, there are no facilities for the storage of large quantities of gas within the state. All the gas is "piped in" and distributed by the local public utility companies. These companies are interested in the possibilities for the underground storage of natural gas, but there are no obvious underground reservoirs such as depleted oil or gas fields.

RI5 Planktonic Foraminifera and the Cretaceous-Tertiary Boundary in Central Delaware

RI5 Planktonic Foraminifera and the Cretaceous-Tertiary Boundary in Central Delaware

The uppermost Cretaceous and lowermost Tertiary planktonic Foraminifera obtained from cores taken in a deep well near Dover, Delaware are studied. The Cretaceous foraminifers are of the Heterohelix-Globotruncana assemblage and are probably of late Maescrichtian age. The Danian Globorotalia compressa - Globigerinoides daubjergensis zone lies immediately above. The Cretaceous-Tertiary boundary is at a depth of approximately
980 feet and lies within a gray, glauconitic silt.

RI3 Wells for the Observation of Chloride and Water Levels in Aquifers that Cross the Chesapeake and Delaware Canal

RI3 Wells for the Observation of Chloride and Water Levels in Aquifers that Cross the Chesapeake and Delaware Canal

Three test wells were drilled near the banks of the Chesapeake and Delaware Canal, in aquifers formed by sand beds in two geologic units, the nonmarine Cretaceous sediments and the Magothy formation, which crop out along the sides and across the bottom of the canal. The canal carries tidal flow from the Delaware River to and from Chesapeake Bay. The purpose of the wells was to determine whether salt water from the canal has entered the water-bearing beds of these formations, and to determine the head of water in them. It was found that the sands contain fresh water, uncontaminated, and that apparently there was discharge of fresh water from the aquifers to the canal under low head, at least from the winter of late 1955 through early autumn 1957.

DGS reports on hydrogeology of southern New Castle County

OFR49 Hydrologeologic Framework Of Southern New Castle County

The Delaware Geological Survey (DGS) at the University of Delaware has released a new technical report on the hydrogeology of southern New Castle County that documents results of an intensive review and analysis of published information and existing geologic and hydrologic data obtained from DGS borehole records and sample library.
