However, the discovery of Paleozoic fields in resources with the bulk of the reserves reservo/red in the the late 1980s has encouraged further exploration in the Paleozoic. This paper reviews the salient features of the Paleozoic petroleum geology in central Saudi Arabia and discusses the main factors controlling hydrocarbon accumulation in the Paleozoic. The Lower Silurian Qusaiba hot shale is the principal source rock for the hydrocarbons discovered in the Ordovician to Permian reservoirs. Of them, the Permo- Carboniferous Unayzah and Upper Ordovician Sarah Formations have the best exploration potential. The key factors controlling hydrocarbon accumulation in the Unayzah Formation are migration pathways and reservoir petrophysics. The key factors controlling hydrocarbon accumulation in the Sarah Formation are reservoir petrophysics and the development of structural traps.展开更多

This phenomenon was observed near a school building and residential area and became a serious risk to occupants and residents. The survey was carried out applying geotechnical techniques which included advancing rotary boreholes to depths of 23 m to 30 m with sampling and testing. The evaluation process also included resistivity imaging profiles using 2D electrical resistivity measurements. Results obtained from this research showed a thick top layer of silty clayey sand soil rich of gypsum and carbonate presenting a hazardous and high-risk soil type. The percentage of fines that are likely to be washed out as a result of chemical disintegration and exposure to significant hydraulic gradient was of great concern. Assessment was made using combined geotechnical and geophysical approach in addition to chemical tests. Based on the data collected and analysis of test results a practical solution was suggested to solve this problem. The use of “cut-off wall” in order to reduce the level of subsurface scour and cajuvity formation were found appropriate. The depth of the cut off wall was determined based on the subsurface geological profile. Advantages of this approach and concerns need to be considered in adopting typical solutions that are presented.展开更多

Both men, it appears, can trace a common descent4 from a personage known as John Cooke who came to America on the Mayflower. John married Sarah Warren; one of their daughters was the great-great-great-great-great-great-grandmother of Sara Delano, FDR’s mother, and another was a direct ancestress5 of Churchill’s American-born mother, Jennie Jerome.展开更多

This study analyzes Palin＇s rhetoric using a three-step approach to Burke＇s concept of victimage： （1） identification of self as victim, （2） identification of a scapegoat who can be blamed for the victim＇s problems, and （3） catharsis or tragic dignification. The results of the analysis indicated that Palin＇s rhetorical strategy emerged during the 2008 election and was fully functional by the time she resigned as Alaska Governor in July 2009. Eventually, victimage rhetoric became her most constant rhetorical theme. Her approach was only partially successful, increasing her positive image among Republicans but contributing to a negative image among Democrats and independents.展开更多
