New geologic map; donations to GMC
The Alaska Department of Natural Resources Division of Geological and Geophysical Surveys has published a geologic map of the east-central North Slope.
The work, funded by the state and the U.S. Geological Survey’s STATEMAP program, covers more than 1,200 square miles of the south-central Sagavanirktok Quadrangle of northern Alaska, the division said, a region “near existing infrastructure and prospective for oil and gas resources.”
The 1:63,360-scale geologic map represents original field work conducted by DGGS in collaboration with DNR’s Division of Oil and Gas.
“Data from more than 800 field stations were integrated with available well log and seismic data to produce a robust interpretation of the stratigraphy and structural geology. Important findings include the discovery of several new oil-stained locations and the documentation of fold geometries - a key component in evaluating hydrocarbon trapping mechanisms,” DGGS said.
A 24-page explanatory booklet accompanies the map, along with a structural cross section, a well-log correlation, and a new regional chronostratigraphic diagram.
Map and related products can be downloaded at no charge from the DGGS website at http://dx.doi.org/10.14509/29138.
New donations to GMC Renovations have been completed at the new Geologic Materials Center, managed by DGGS, and in early April the entire GMC collection will begin relocating to the new center in East Anchorage.
“New donations are arriving now and we anticipate many more once the facility is fully functioning in mid-2015,” said Steve Masterman, the state geologist and DGGS director.
Recent oil-related donations include 300-plus feet of core from the Umiat No. 18 oil and gas well from Linc Energy.
