Schlumberger Brothers
Conrad Schlumberger (2 October 1878 in Gebweiler ( Alsace-Lorraine) – 9 May 1936 in Stockholm) and Emile Henry Marcel Schlumberger (21 June 1884 in Gebweiler – 9 May 1953 in Val-Richer) were brothers from the region of Alsace-Lorraine, France, then a part of the German Empire. Their inventions in the area of geophysics and well logging were the beginnings of Schlumberger Well Services and the entire well logging industry. Life and work Conrad and Marcel were two of six children of an affluent Alsatian Protestant family. Their father, Paul, was descended from a wealthy cotton weaving family. Their mother, Marguerite De Witt, was a political activist. When the brothers were born, their native province Alsace was part of Germany. Their parents decided to send the brothers to Paris to be educated. Both Conrad and Marcel were educated at the top engineering schools in France; Conrad graduated from École Polytechnique in 1900, whereas Marcel graduated from École Centrale Pa ...

Petroleum Reservoir
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. Petroleum reservoirs are broadly classified as ''conventional'' and '' unconventional'' reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil 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 accumulation of liquid oil underground in multiple (potentially linked) reservoirs, trapped as it rises by impermeable rock formations. In industrial terms, an o ...

Curaçao
Curaçao ( ; ; pap, Kòrsou, ), officially the Country of Curaçao ( nl, Land Curaçao; pap, Pais Kòrsou), is a Lesser Antilles island country in the southern Caribbean Sea and the Dutch Caribbean region, about north of the Venezuela coast. It is a constituent country of the Kingdom of the Netherlands. Together with Aruba and Bonaire, it forms the ABC islands. Collectively, Curaçao, Aruba, and other Dutch islands in the Caribbean are often called the Dutch Caribbean. Curaçao was formerly part of the Curaçao and Dependencies colony from 1815 to 1954 and later the Netherlands Antilles from 1954 to 2010, as Island Territory of Curaçao ( nl, Eilandgebied Curaçao, links=no, pap, Teritorio Insular di Kòrsou, links=no), and is now formally called the Country of Curaçao. It includes the main island of Curaçao and the much smaller, uninhabited island of Klein Curaçao ("Little Curaçao"). Curaçao has a population of 158,665 (January 2019 est.), with an area of ; its ...

Willemstad
Willemstad ( , ; ; en, William I of the Netherlands, William Town, italic=yes) is the capital city of Curaçao, an island in the southern Caribbean Sea that forms a Countries of the Kingdom of the Netherlands, constituent country of the Kingdom of the Netherlands. It was the capital of the Netherlands Antilles prior to its Dissolution of the Netherlands Antilles, dissolution in 2010. The historic centre of the city consists of four quarters: the Punda and Otrobanda, which are separated by the Sint Anna Bay, an inlet that leads into the large natural harbour called the Schottegat, as well as the Scharloo and Pietermaai Smal quarters, which are across from each other on the smaller Waaigat harbour. Willemstad is home to the Curaçao synagogue, the oldest surviving synagogue in the Americas. The city centre, with its unique architecture and harbour entry, has been designated a UNESCO World Heritage Site. History Punda was established in 1634, when the Dutch captured the island fro ...

Well Test (oil And Gas)
In the petroleum industry, a well test is the execution of a set of planned data acquisition activities. The acquired data is analyzed to broaden the knowledge and increase the understanding of the hydrocarbon properties therein and characteristics of the underground reservoir where the hydrocarbons are trapped. The test will also provide information about the state of the particular well used to collect data. The overall objective is identifying the reservoir's capacity to produce hydrocarbons, such as oil, natural gas and condensate. Data gathered during the test period includes volumetric flow rate and pressure observed in the selected well. Outcomes of a well test, for instance flow rate data and gas oil ratio data, may support the well allocation process for an ongoing production phase, while other data about the reservoir capabilities will support reservoir management. Scope and definitions There are many flavours of well tests and various ways to categorize test types ...

Formation Evaluation
In petroleum exploration and development, formation evaluation is used to determine the ability of a borehole to produce petroleum. Essentially, it is the process of "recognizing a commercial well when you drill one". Modern rotary drilling usually uses a heavy mud as a lubricant and as a means of producing a confining pressure against the formation face in the borehole, preventing blowouts. Only in rare and catastrophic cases, do oil and gas wells ''come in'' with a fountain of gushing oil. In real life, that is a '' blowout''—and usually also a financial and environmental disaster. But controlling blowouts has drawbacks—mud filtrate soaks into the formation around the borehole and a mud cake plasters the sides of the hole. These factors obscure the possible presence of oil or gas in even very porous formations. Further complicating the problem is the widespread occurrence of small amounts of petroleum in the rocks of many sedimentary provinces. In fact, if a sed ...

Alsace
Alsace (, ; ; Low Alemannic German/ gsw-FR, Elsàss ; german: Elsass ; la, Alsatia) is a cultural region and a territorial collectivity in eastern France, on the west bank of the upper Rhine next to Germany and Switzerland. In 2020, it had a population of 1,898,533. Alsatian culture is characterized by a blend of Germanic and French influences. Until 1871, Alsace included the area now known as the Territoire de Belfort, which formed its southernmost part. From 1982 to 2016, Alsace was the smallest administrative ''région'' in metropolitan France, consisting of the Bas-Rhin and Haut-Rhin departments. Territorial reform passed by the French Parliament in 2014 resulted in the merger of the Alsace administrative region with Champagne-Ardenne and Lorraine to form Grand Est. On 1 January 2021, the departments of Bas-Rhin and Haut-Rhin merged into the new European Collectivity of Alsace but remained part of the region Grand Est. Alsatian is an Alemannic dialect closely related ...

Fortune Global 500
The ''Fortune'' Global 500, also known as Global 500, is an annual ranking of the top 500 corporations worldwide as measured by revenue. The list is compiled and published annually by ''Fortune'' magazine. Methodology Until 1989, it listed only non-United States industrial corporations under the title "International 500" while the ''Fortune'' 500 contained and still contains exclusively United States corporations. In 1990, United States companies were added to compile a truly global list of top industrial corporations as ranked by sales. Since 1995, the list has had its current form, listing also top financial corporations and service providers by revenue. Several inconsistencies exist in ''Fortune'' ranking of cities with the most ''Fortune'' 500 headquarters. On June 3, 2011, the ''Atlanta Business Chronicle'' stated examples of ''Fortune'' including regional headquarters for some cities, excluding regional headquarters for other cities and in some cases excluding headquarte ...
