AIPG-TX WEBINAR ANNOUNCEMENT – April 18, 2023 – 7:00 PM
“USING ALTERATION AS A HYDROCARBON EXPLORATION TOOL:
REMOTE SENSING AT LISBON VALLEY REVISITED”
The Lisbon Valley, UT, area is one of the classical locations for the study of surface mineral alteration associated with the presence of an underlying hydrocarbon field. The Wingate sandstone at surface over the Lisbon Valley field is bleached and kaolinized. However, the geology at Lisbon Valley is complicated: hydrothermal copper and uranium deposits, and clay alteration occur along the Lisbon Valley Fault, and the Lisbon Valley field lies beneath several thousand feet of bedded evaporites, casting some doubt on the alteration being due to microseepage from the oilfield. On the other hand, relatively recent soil surveys suggest that hydrocarbon gases are still moving vertically upward from the field. The speaker discusses how he attempted to resolve these issues by quantitatively estimating the amount of seepage required to create the observed alteration, and by examining the stratigraphic, structural and thermal history of the area to determine when the field matured and when the trap formed.
SPEAKER
John Berry has over 50 years of geological experience in metals and hydrocarbon exploration on six continents and in deep-water basins offshore. During the latter part of his career he specialized in the application of remote sensing techniques to on- and offshore hydrocarbon exploration as well as base and precious metals exploration. He holds an AB degree from the University of Pennsylvania and an M.A. in geology and geophysics from Columbia University, where he workd in the Arctic Section at Lamont-Docherty Observatory.
