Basement rocks are among the most important targets in recent exploration efforts in Yemen. Hydrocarbons within fractured basement rocks were detected more than a decade ago in ten blocks. Currently, only five out of those ten blocks (Blocks 14, 10, 32-S, 53-S, and S2) are producing (four are located in the Masilah Basin and one in the Sab'atayn Basin)

Natural Resources of Yemen are Petroleum, Fish, Rock Salt Marble,small deposits of coal, gold, lead, nickel, and copper; fertile soil in the west.

highly fractured Late Triassic to Late Cretaceous granitic and granodiorites basement rocks (Cuong and Warren, 2009). It is estimated that two billion barrels of oil (Keggin and Alaaraji, 2017), sourced from directly overlying Oligocene lacustrine shales (Hung and Le, 2004), will be produced from the fractured granitic basement. Other significant discoveries have been made in the Yemen East ...

15.02.2011 · Hundreds of anti-government demonstrators and government loyalists fought with rocks and batons in the Yemeni capital on Tuesday in political unrest fueled by Egypt's uprising.

The geology of Yemen includes extremely ancient Precambrian igneous and metamorphic crystalline basement rocks overlain by sediments from the Paleozoic, Mesozoic and Cenozoic, deposited in shallow seas and lakebeds, overlain by thick volcanic rocks and loess.Erosion has played a major role in Yemen's geologic history and eliminated many rock units over time.

The exposed rock units in the investigated area are related to Pre-Cambrian basement, the Jurassic limestone (Amran Group), Cretaceous sandstones (Tawilah Group). Tertiary volcanics (Yemen Trap Series), and Quaternary basaltic lavas and alluvial deposits . Following is a brief discussion of the major rock units representing the area of study.

located in Jayshan district, Abyan governorate, Republic of Yemen. This basin lies between longitudes 46. o. 10‟ to 46. o. 40‟ and latitudes 14. o. 00‟ to 14. o . 40‟ (Figure 1). The climate of the study area is tropic-arid. It is essentially affected by the monsoon winds of the Indian Ocean. The climate is moderate in summer and cold ...

The country has rich reserves of copper, nickel, lead, gold, coal, marble, rock salt and petroleum. Yemen is highly dependent on its declining oil resources for revenue. Petroleum exports contribute to nearly 25% of the GDP growth and 70% of the government revenue. The GDP of the country was estimated to be $58.71 billion in 2011. The country has tried to diversify its economy by initiating an ...

Introduction of a Rock Typing Methodology in Crystalline Basement Reservoirs (Yemen)* Jan Steckhan. 1 and Roman Sauer. 1 Search and Discovery Article #40524 (2010) Posted April 26, 2010 *Adapted from extended abstract prepared for presentation at AAPG International Conference and Exhibition, Rio de Janeiro, Brazil, November 15-18, 2009 . 1

Continental crust. Basement rock is the thick foundation of ancient, and oldest, metamorphic and igneous rock that forms the crust of continents, often in the form of granite. Basement rock is contrasted to overlying sedimentary rocks which are laid down on top of the basement rocks after the continent was formed, such as sandstone and limestone.The sedimentary rocks which may be deposited on ...

Some 85 percent of the land-area of Andhra Pradesh is underlain by the weathered granitic basement 'hard-rock' aquifer system, which forms ... control of groundwater abstraction using a regulatory approach and economic tools when faced with associated environmental ...

F. Geukens, who had worked in Yemen; and Z. R. Beydoun, who had studied the Eastern Aden Protectorate. With the close cooperation of the authors, the new data were added to data already plotted on the base map of the Arabian Peninsula.

The overlying Devonian–Mississippian Woodford Shale is the major petroleum source rock for the Hunton Group in the field, based on one-dimensional and four-dimensional petroleum system models that were calibrated to well temperature and Woodford Shale vitrinite reflectance data.

The rock layer below which economic hydrocarbon reservoirs are not expected to be found, sometimes called economic basement. Basement is usually older, deformed igneous or metamorphic rocks, which seldom develops the porosity and permeability necessary to serve as a hydrocarbon reservoir, and below which sedimentary rocks are not common. Basement rocks typically have different density ...

The fractured basement field in Yemen described in this paper is characterized by two types of fracturing: background fractures with a very low effective permeability of less than 0.001 md and fracture corridors with an effective permeability of up to several millidarcies. Except for some dissolution porosity related to fracture corridors, no significant matrix porosity is encountered (total ...

It restricted travel from Chad, Iran, Libya, North Korea, Somalia, Syria, Venezuela and Yemen. In December, the Supreme Court allowed the ban to go into full effect, pending legal challenges.

emplacement of the thick trap rock sequences in Yemen (Guekens, 1966). The early Tertiary sedimentary record in the Red Sea area is incomplete and has been the subject of debate. It is generally agreed that during Eocene time transgressive marine deposits developed in the northern Sinai and Egypt and that Eocene rocks may occur as far south as Mag-hersum Island, Sudan (Said, 1962; Whiteman ...

Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).
