South Lokichar Basin
The South Lokichar Basin is a Cenozoic sedimentary basin in Kenya. It is part of the East African Rift system, although it is no longer active. Since 2012 it has been the location of a series of oil discoveries by Tullow Oil and its partners. Geometry The South Lokichar Basin is a north–south trending half-graben with the main bounding fault on its western margin. It is approximately 80 km long, 25 km wide and has a maximum depth of over 7 km. The main fault, known as the Lokichar Fault, is relatively low angle and planar in section, although the dip varies considerably along strike from 12° to 60°. Fill The basin is filled by a sequence of Oligocene (possibly as old as Eocene) to Miocene sedimentary rocks. There is one major interval of volcanic rocks near the top of the sequence called the Auwerwer basalts, dated using K–Ar dating as middle to late Miocene in age (12.5–10.7 Ma). Hydrocarbon exploration Exploration in the basin began with the Loperot-1 wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenozoic
The Cenozoic Era ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterized by the dominance of mammals, insects, birds and angiosperms (flowering plants). It is the latest of three geological eras of the Phanerozoic Eon, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians ( placentals) in the Northern Hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the Southern Hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that large m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daily Nation
The ''Daily Nation'' is a Kenyan newspaper. It was founded in 1958 and is published in Nairobi. History The ''Daily Nation'' was started in the year 1958 as a Swahili weekly called ''Taifa'' by the Englishman Charles Hayes. It was bought in 1959 by the Aga Khan, and became a daily newspaper, ''Taifa Leo'' (Swahili for "Nation Today"), in January 1960. An English-language edition called ''Daily Nation'' was published on 3 October 1960, in a process organised by former editor of the British '' News Chronicle'', Michael Curtis. The publisher was East African Newspapers (Nation Series) Ltd, which later became the Nation Media Group, with operations throughout the African Great Lakes region and is owned by the Aga Khan. Goan Kenyan journalist Cyprian Fernandes worked at the ''Daily Nation'' and ''Sunday'' ''Nation'' from 1960 until he was forced to flee Kenya around 1973, owing to his investigative journalism probing irregularities which came too close to the government under ...

Kenya Crude Oil Pipeline
Kenya Crude Oil Pipeline, also Lokichar–Lamu Crude Oil Pipeline, is a proposed crude-oil pipeline in Kenya. The pipeline will originate in the oil-rich South Lokichar Basin, near the town of Lokichar, in northwest Kenya to end at Port Lamu, on the Indian Ocean. The route will remain as originally planned in the Uganda–Kenya Crude Oil Pipeline, in August 2015. The route, was proposed by Toyota Tsusho, the consultant selected by the two governments of that now-abandoned project. Overview Kenya has confirmed crude oil deposits of at least 750 million barrels. Originally Kenya partnered with Uganda to export that oil through a joint pipeline to Port Lamu on the Indian Ocean coast. When those plans fell through, Kenya announced it would build ts own pipeline from Lokichar to Lamu. The projected length of this pipeline is about The pipeline would carry anywhere from 80,000 to 120,000 barrels of crude oil every 24 hours, using 50 MW of electricity. At that rate, the available kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farmout Agreement
In the oil and gas industry, a farmout agreement is an agreement entered into by the owner of one or more mineral leases, called the "farmor", and another company who wishes to obtain a percentage of ownership of that lease or leases in exchange for providing services, called the "farmee." The typical service described in farmout agreements is the drilling of one or more oil and/or gas wells. A farmout agreement differs from a conventional transaction between two oil and gas lessees, because the primary consideration is the rendering of services, rather than the simple exchange of money. Farmout agreements typically provide that the farmor will assign the defined quantum of interest in the lease(s) to the farmee upon the farmee finishing: (1) the drilling of an oil and/or gas well to the defined depth or formation, or (2) drilling of an oil and/or gas well and the obtaining of commercially viable production levels. Farmout Agreements are the second most commonly negotiated agreem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Production Sharing Agreement
Production sharing agreements (PSAs) or production sharing contracts (PSCs) are a common type of contract signed between a government and a resource extraction company (or group of companies) concerning how much of the resource (usually oil) extracted from the country each will receive. Description Production sharing agreements were first used in Bolivia in the early 1950s, although their first implementation similar to today's was in Indonesia in the 1960s. Today they are often used in the Middle East and Central Asia, overall 40 countries worldwide. In production sharing agreements the country's government awards the execution of exploration and production activities to an oil company. The oil company bears the mineral and financial risk of the initiative and explores, develops and ultimately produces the field as required. When successful, the company is permitted to use the money from produced oil to recover capital and operational expenditures, known as "cost oil". The rema ...

Africa Oil Corp
Oil exploration in Puntland, an autonomous region in northeastern Somalia which is a federal state, began in the mid-2000s as a series of negotiations between the provincial administration and foreign oil companies. By 2012, exploratory wells established in the area yielded the first signs of crude oil. Overview Somalia has untapped reserves of numerous natural resources, including uranium, iron ore, tin, gypsum, bauxite, copper, salt and natural gas. The Puntland region in northeastern Somalia, in particular, came to be regarded as the geological analogue of Yemen since both areas once formed a single landmass around 18 million years ago, before the Gulf of Aden rifted and separated the Horn of Africa from the Arabian Peninsula. The oil reserves discovered in Yemen's Cretaceous and Jurassic formations were therefore also thought to potentially exist in Puntland, with petroleum geologists associating the Nugaal and Dharoor blocks with the South Yemen Marib-Shabwa and Sayun-Masila ...

Reservoir (geology)
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust. Reservoirs are broadly classified as ''conventional'' and '' unconventional'' reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil (petroleum) or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs the rocks have high porosity and low permeability, which keeps the hydrocarbons trapped in place, therefore not requiring a cap rock. Reservoirs are found using hydrocarbon exploration methods. Oil field An oil field is an area of accumulated liquid petroleum underground in multiple (potentially linked) reservoirs, trapped as it rises to impermeable rock formations. In industrial term ...

Source Rock
In petroleum geology, source rock is a sedimentary rock which has generated hydrocarbons or which has the potential to generate hydrocarbons. Source rocks are one of the necessary elements of a working petroleum system. They are organic-rich sediments that may have been deposited in a variety of environments including deep water marine, lacustrine and deltaic. Oil shale can be regarded as an organic-rich but immature source rock from which little or no oil has been generated and expelled. Subsurface source rock mapping methodologies make it possible to identify likely zones of petroleum occurrence in sedimentary basins as well as shale gas plays. Types of source rocks Source rocks are classified from the types of kerogen that they contain, which in turn governs the type of hydrocarbons that will be generated: * Type I source rocks are formed from algal remains deposited under anoxic conditions in deep lakes: they tend to generate waxy crude oils when submitted to thermal st ...

Royal Dutch Shell
Shell plc is a British multinational oil and gas company, headquartered in London, England. Shell is a public limited company with a primary listing on the London Stock Exchange (LSE) and secondary listings on Euronext Amsterdam and the New York Stock Exchange. A core component of Big Oil, Shell is the second largest investor-owned oil and gas company in the world by revenue (after ExxonMobil), and among the world's largest companies out of any industry. Measured by both its own emissions, and the emissions of all the fossil fuels it sells, Shell was the ninth-largest corporate producer of greenhouse gas emissions in the period 1988–2015. Shell was formed in April 1907 through the merger of Royal Dutch Petroleum Company of the Netherlands and The "Shell" Transport and Trading Company of the United Kingdom. The combined company rapidly became the leading competitor of the American Standard Oil and by 1920 Shell was the largest producer of oil in the world. Shell first ente ...

Year
A year is a unit of time based on how long it takes the Earth to orbit the Sun. In scientific use, the tropical year (approximately 365 Synodic day, solar days, 5 hours, 48 minutes, 45 seconds) and the sidereal year (about 20 minutes longer) are more exact. The modern calendar year, as reckoned according to the Gregorian calendar, approximates the tropical year by using a system of leap years. The term 'year' is also used to indicate other periods of roughly similar duration, such as the lunar year (a roughly 354-day cycle of twelve of the Moon's phasessee lunar calendar), as well as periods loosely associated with the calendar or astronomical year, such as the seasonal year, the fiscal year, the academic year, etc. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar climate, subpolar regions around the planet, four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
