Formation Evaluation of Upper Nubian Sandstone Block NC 98 (A Pool), Eastern Sirt Basin, Libya
International Science and العدد Volume 12 Technology Journal ديسمبر December 2017 المجلة الدولية للعلوم والتقنية Formation Evaluation of Upper Nubian Sandstone Block NC 98 (A Pool), Eastern Sirt Basin, Libya. Hussein A. Sherif and Ayoub M. Abughdiri Libyan Academy-Janzour, Tripoli, Libya [email protected] ABSTRACT The Nubian Sandstone Formation (Pre-Upper Cretaceous) in the Sirte Basin, Libya is considered an important reservoir for hydrocarbons. It is subdivided into three stratigraphic members, the Lower Nubian Sandstone, the Middle Shale and the Upper Nubian Sandstone. Generally, the oil wells which have been drilled by Waha Oil Company in A-Pool, NC98 Block, Eastern Sirt Basin, Libya are producing from the Upper Nubian Sandstone reservoir. The main trapping systems in APool-NC98 Block are structural and stratigraphic combination traps, comprising of at least two major NW-SE trending tectonic blocks, with each block being further broken up with several more Pre-Upper-Cretaceous faults. Four wells have been selected to conduct the formation evaluation of the Upper Nubian Sandstone reservoir which lies at a depth of between 14,000 and 15,500 feet. This study is an integration approach using the petrophysical analysis and integrating the sedimentology and petrography from core. The geological and petrophysical evaluation were done using the Techlog software. The clay minerals identification was carried out using the Potassium (K) versus Thorium (Th) concentration cross-plot technique. The main clay minerals identified were; Kaolinite and Chlorite, in agreement with the Petrographical analysis on samples from well A4-NC98. The Petrophysical analysis clearly shows that the Upper Nubian Sandstone is a good reservoir in wells A3, A4 and A5, whereas low reservoir quality in well A6. -

Lyons Available online 12 March 2007 Abstract The geochemistry and isotopic composition (H, O, S, Osulfate, C, Sr) of groundwater from the Nubian Sandstone (Kurnub Group) aquifer in the Negev, Israel, were investigated in an attempt to reconstruct the origin of the water and solutes, evaluate modes of water–rock interactions, and determine mean residence times of the water. The results indi- cate multiple recharge events into the Nubian sandstone aquifer characterized by distinctive isotope signatures and deu- terium excess values. In the northeastern Negev, groundwater was identified with deuterium excess values of 16&, 18 2 which suggests local recharge via unconfined areas of the aquifer in the Negev anticline systems. The d OH2O and d H values (À6.5& and À35.4&) of this groundwater are higher than those of groundwater in the Sinai Peninsula and southern Arava valley (À7.5& and À48.3&) that likewise have lower deuterium excess values of 10&. -

It is the world’s largest ‘fossil’ water aquifer system. This gigantic reservoir faces heavy demands from agriculture and for drinking water, and the amount drawn out could double in the next 50–100 years. Climate change is expected to add significant stress due to rising temperatures as well as changes in precipitation patterns, inland evaporation and salinization. Groundwater has been identified as the biggest and in some cases the only future source of water to meet growing demands and the development goals of each NSAS country, and evidence shows that massive volumes of groundwater are still potentially available. Since the 1960s, groundwater has been actively pumped out of the aquifer to support irrigation and water supply needs. Over-abstraction has already begun in some areas, which leads to significant drawdowns and can induce salinization. In the approximately 20 000 years since the last glacial period, the aquifer has been slowly draining; the system faces low recharge rates in some areas, while others have no recharge at all. -

A. Harrell1 From Early Dynastic times onward, limestone was the construction material of choice for An- cient Egyptian temples, pyramids, and mastabas wherever limestone bedrock occurred, that is, along the Mediterranean coast, in the northern parts of the Western and Eastern Deserts, and in the Nile Valley between Cairo and Esna (fig. 1). Sandstone bedrock is present in the Nile Valley from Esna south into Sudan as well as in the adjacent deserts, and within this region it was the only building stone employed.2 Sandstone was also imported into the Nile Valley’s limestone region as far north as el-‘Sheikh Ibada and nearby el-‘Amarna, where it was used for New Kingdom tem- ples. There are sandstone temples further north in the Bahariya and Faiyum depressions, but these were built with local materials. The first large-scale use of sandstone occurred near Edfu in Upper Egypt, where it was employed for interior pavement and wall veneer in an Early Dynastic tomb at Hierakonpolis3 and also for a small 3rd Dynasty pyramid at Naga el-Goneima.4 Apart from this latter structure, the earliest use of sandstone in monumental architecture was for Middle Kingdom temples in the Abydos-Thebes region with the outstanding example the 11th Dynasty mortuary temple of Mentuhotep II (Nebhepetre) at Deir el-Bahri. -

Geological Survey, Denver, Colorado Page 1 of 21 The Red Sea Basin Province: Sudr-Nubia(!) and Maqna(!) Petroleum Systems2 Sandra J. Lindquist, Consultant to U.S. Geological Survey, Denver, CO World Energy Project October, 1998 FOREWORD This report is a product of the World Energy Project of the U.S. Geological Survey, in which the world has been divided into 8 regions and 937 geologic provinces for purposes of assessment of global oil and gas resources (Klett and others, 1997). These provinces have been ranked according to the discovered petroleum volumes within each; high- ranking provinces (76 “priority” provinces exclusive of the U.S.) and others with varying types and degrees of intrigue (26 “boutique” provinces exclusive of the U.S.) were chosen for appraisal of oil and gas resources. The petroleum geology of these non-U.S. priority and boutique provinces are described in this series of reports. A detailed report containing the assessment results for all provinces will be available separately. The Total Petroleum System concept is the basis for this assessment. A total petroleum system includes the essential elements and processes, as well as all genetically related hydrocarbons that occur in petroleum shows, seeps and accumulations (discovered and undiscovered), whose provenance is a pod or related pods of mature source rock (concept modified from Magoon and Dow, 1994). -

Innovative Solutions for Water Wars in Israel, Jordan, and The
INNOVATIVE SOLUTIONS FOR WATER WARS IN ISRAEL, JORDAN AND THE PALESTINIAN AUTHORITY J. David Rogers K.F. Hasselmann Chair, Department of Geological Engineering 129 McNutt Hall, 1870 Miner Circle University of Missouri-Rolla, Rolla, MO 65409-0230 [email protected] (573) 341-6198 [voice] (573) 341-6935 [fax] ABSTRACT In the late 1950s Jordan and Israel embarked on a race to collect, convey and disperse the free-flowing waters of the Jordan River below the Sea of Galilee. In 1955 the Johnston Unified Water Plan was adopted by both countries as a treaty of allocation rights. By 1961 the Jordanians completed their 110-km long East Ghor Canal, followed by Israel’s 85-km long National Water Carrier, initially completed in 1964 and extended in 1969. The Johnston allocation plan was successfully implemented for 12 years, until the June 1967 war between Israel and her neighbor Arab states. The Israelis have spearheaded the effort to exploit the region’s limited water resources, using wells, pipelines, canals, recharge basins, drip irrigation, fertigation, wastewater recharge, saline irrigation and, most recently, turning to desalination. In 1977 they began looking at various options to bring sea water to the depleted Dead Sea Basin, followed by similar studies undertaken by the Jordanians a few years later. A new water allocation plan was agreed upon as part of the 1994 Israel-Jordan peace treaty, but it failed to address Palestinian requests for additional allotments, which would necessarily have come from Jordan or Israel. The subject of water allocation has become a non-negotiable agenda for the Palestinian Authority in its ongoing political strife with Israel.
