Downhole Logging for the Cape Roberts Project

该奖项支持计划中的四个罗伯茨角科学钻孔的连续岩心和井下测井。该项目的目标是研究早第三纪和白垩纪的气候、构造和海平面变化的记录，并确定南极冰川的开始时间。地球物理测井记录将被转换为连续的变化记录，这可以被解释为指示矿物学和孔隙度的变化。每个井的详细一维记录将与现有的高分辨率地震数据相结合，以产生对地层的二维解释。这一地球物理测井方案是钻探现场基本特征的重要组成部分，也是为解释有关岩心的其他科学工作而建立地层框架的努力的基本组成部分。

Abstract OPP 9418429 This award supports continuous-core and downhole logging of the four planned Cape Roberts Project scientific drill holes. The goal of the Project is to study the Early Tertiary and Cretaceous record of climate, tectonics, and sea level change, and to determine the time of onset of Antarctic glaciation. Geophysical well logs will be converted into continuous records of variation which can be interpreted as indicating variations in mineralogy and porosity. The detailed one-dimensional records at each hole will be integrated with available high resolution seismic data to produce a two-dimensional interpretation of the stratigraphy. This geophysical logging program is an essential component of basic characterization of the drill site and is a fundamental part of the effort to produce a stratigraphic framework for interpretation of other scientific work on the core.
