San Jorge gulf is the leader in oil extraction. 46,000 m per day are extracted in the zone, representing 46% of total crude oil production in the nation. Comodoro Rivadavia is situated in the south of Argentina in the province of Chubut, on the coast of San Jorge Gulf. It was necessary to create a port in the area of San Jorge Gulf in order to have shorter routes for transporting products from and to

2277-586: The city in comparison to Argentina. The city size places Comodoro Rivadavia as the 20th largest city of the country and the largest in South Patagonia , which goes from Chubut to Tierra del Fuego . Comodoro Rivadavia is the biggest city to the south of the Colorado River. The city developed from the oil camps which evolved into neighbourhoods. The city is divided into three main areas: North Area, South Area and Downtown Area. The South Area

2346-401: The coldest with an annual mean temperature of 8 °C (46.4 °F) owing to the higher elevations while the coastal areas are the warmest with an annual mean temperature of 12 to 14 °C (53.6 to 57.2 °F). The central parts of the province have an annual mean temperature of 10 to 12 °C (50.0 to 53.6 °F) since they have a higher elevation than the coastal areas. During winter,

Even though the term Tertiary has been declared obsolete, some high school curriculums still teach the geologic periods as Precambrian, Paleozoic, Mesozoic, (Cenozoic-)Tertiary and (Cenozoic-)Quaternary. The term Tertiary

2553-492: The development of the town, further accelerated in the late 1950s by President Arturo Frondizi 's oil campaign to foster the installation of numerous foreign companies. The city evolved around this industry, and even today when this panorama has changed substantially, it is still called the "National Oil Capital." The beach village Rada Tilly was founded on July 24, 1948, and today is an important hub for tourism in Argentina . Oil production has begun to decline in quantity but

2622-572: The discovery due to Argentinian law which decrees that all mineral deposits belong to the state. Therefore, most of the town's Afrikaans settlers moved on to Sarmiento and surrounding regions to set up farms there. The discovery of oil in 1907 boosted economic growth in Comodoro Rivadavia. By the end of 1919, most of the 1719 workers were given accommodation in small metal sheet houses without any heating or electric light with temperatures below zero and winds near 100 km/h. The establishment of Yacimientos Petrolíferos Fiscales (YPF) in 1922 led to

2691-557: The existence of the Tehuelche people , who lived in the area of Rada Tilly some 9000 years ago. This information was confirmed by Father Brea, who some years ago contributed to this theory with the discovery of utensils and human remains near Rada Tilly. It is widely known that the Tehuelche, who came from the north of Patagonia during the warm summer, used to make camp where Rada Tilly is today. The English navigator Robert FitzRoy

2760-560: The first unconventional oil and gas discovery in Chubut from a fracked well in the Early Cretaceous D-129 formation of the Golfo San Jorge basin. Chubut produces 21% of the nation's fish catch. Sheep ranching, though less than half as productive in the 21st century compared to as recently as 1990, remains important at the local level. The advent of synthetic replacements to wool after World War II battered

2829-477: The first state-owned oil company in the world, was created by President Hipólito Yrigoyen 's government. This company helped the society by improving the construction of houses, providing new jobs and health care. Engineer Enrique Mosconi was in charge of running the company. By 1933, 1,648 wells had been drilled in Comodoro Rivadavia; 88.9% of them were economically productive. In 1935 the First Oil Law

2898-468: The inhabitants are in the main cities. They have also settled along the Chubut River . Most areas have a population density of less than 1 inhabitant per square kilometer. Chubut's economy, for a long time one of the most prosperous in Argentina, is one of the country's least diversified. Nearly one-quarter of its 2006 output, estimated at US$ 4.652 billion (or a per capita income of US$ 11,256),

2967-479: The lands around Comodoro Rivadavia. However, due to a shortage of water, they had to bring water in by ox wagon with the lack of it being a big impediment to the development of the settlement. At the Afrikaners' insistence drilling began in 1907 in an effort to look for water but instead they struck oil. Although much of the oil was discovered on land given to Afrikaans settlers, they could not benefit directly from

3036-512: The mean temperature in the coldest months ranges from 6 to 7 °C (42.8 to 44.6 °F) in the northern parts of the province to 4 to 7 °C (39.2 to 44.6 °F) in the southern parts. In the Andes, the mean temperature can be close to 0 °C (32.0 °F). Unlike the northern hemisphere, most of the cold air masses originate from the Pacific Ocean, which moderates the cold air and as such, extreme cold temperatures are rare. Occasionally, cold air masses from Antarctica are not moderated by

3105-590: The moisture from the Pacific Ocean from coming in, causing it to release most of the precipitation on its western slopes, most of the province is dry, averaging less than 200 mm (7.9 in) a year. In the central parts of the province, some areas receive less than 100 mm (3.9 in) of precipitation a year. In the Andean part, precipitation increases towards the Chilean border and precipitation ranges from 700 mm (28 in) to over 3,000 mm (120 in). A Mediterranean like precipitation pattern, similar to central Chile with dry summers and wet winters

3174-459: The moisture precipitates on the western side of the Andes, leaving all except the Andean portion of the province dry. In the Andean region, the climate is cold for its latitude owing to the higher elevations there and the influence of winds from the Pacific Ocean. The peaks are usually snow covered throughout the year. In this region, precipitation ranges from 700 mm (28 in) to over 2,500 mm (98 in) in some areas. The central parts of

3243-419: The mountains. Most of these valleys existed before the Andes were formed. The lakes, which are mostly located in the western parts of the province are of glacial origin because during the last ice age , the movement of the glaciers lead to the formation of extensive areas of depressions that were filled up with water to form the lakes today. The Andes cause humid winds from the Pacific Ocean to rise so most of

3312-450: The necessity of a port in the area of San Jorge Gulf . This necessity made possible the foundation of Comodoro Rivadavia, today capital of petroleum in Argentina. The first governor of Gobernación Nacional del Chubut was Colonel Luis Jorge Fontana , who traveled around the whole extension attributed to Chubut commanding a numerous group of Welsh immigrants in 1885. American researcher Junius Bird and Finnish geographer Väinö Auer confirmed

3381-508: The north. The westernmost parts of the province are the coolest during the summer, averaging only 14 °C (57.2 °F). The central parts of the province have the most extreme temperatures which can reach over 40 °C (104.0 °F) during the summer and below −20 °C (−4.0 °F) in the winter. The lowest temperature recorded in Chubut was −33 °C (−27.4 °F) in Sarmiento. In general, relative humidity values do not vary

3450-411: The ocean, resulting in very cold temperatures. During summer, the temperature gradient is greater than in the winter. The northern parts of the province, have a mean temperature greater than 20 °C (68.0 °F) in the warmest months while in the southern parts, the mean temperature in the warmest month ranges from 17 to 19 °C (62.6 to 66.2 °F) owing to the influence of subtropical air from

Print newspapers include: Online journalism has a small, growing presence in Chubut. The six print newspapers have online editions; these are updated every 24 hours. Some new digital proposals make a better use of web's potential. One case

3657-416: The province have an arid climate with hot, sunny summers but cold winters and only average 200 mm (7.9 in) of precipitation a year. The central parts of the province are very windy throughout the year. The coast has an arid or semi-arid climate with hot, but short summers and cold winters. It is the mildest region in the province with the warmest annual mean temperatures. The coast region's climate

3726-463: The region to which the designations were originally applied (parts of the Alps and plains of Italy), when the same system was later extended to other parts of Europe and to America, it proved to be inapplicable. Therefore, the use of mollusks was abandoned from the definition and the epochs were renamed and redefined. For much of the time during which the term 'Tertiary' was in formal use, it referred to

3795-550: The repair and building of ships in a roofed space without the weather affecting the activity. The shipyard has three travelling cranes of 8 tons each. Works made in the shipyard include the building of eolic mill towers and oil buoys. The port facilities include: The city also is home to a factory that produces concrete, property of Petroquimica Comodoro Rivadavia S.A. It produces different types of concrete: Standard Portland, Puzolanic, BCA, ARI, bricklaying concrete Caltex, concrete for oil industry. The total production of concrete for

In 1833, Charles Lyell incorporated a Tertiary Period into his own, far more detailed system of classification, based on fossil mollusks he collected in Italy and Sicily in 1828-1829. He subdivided the Tertiary Period into four epochs according to the percentage of fossil mollusks resembling modern species found in those strata . He used Greek names: Eocene, Miocene, Older Pliocene, and Newer Pliocene. Although these divisions seemed adequate for

Wool production has risen since 2002, however, and totaled 71,000 tons in 2006. Chubut stretches from the Atlantic to the Andes with 3 distinct environmental regions: The Andes, the central plains and the coastal regions. The Andes in the westernmost parts of the province mostly extend along

4002-417: The south where the average is more than 9 metres per second (30 ft/s). Higher altitude areas are more windy than lower altitude areas, resulting in the Andean region being windier than the coastal areas. As in much of Patagonia, summers tend to be windier than winters. Sunshine in the province follows a north–south gradient (decreases from north to south), particularly during summer where northern parts of

Plans exist to connection it the national energy, which could allow the sale of energy to other regions. The most important sports in the city of Comodoro Rivadavia are basketball, football and car racing, among others such as land yachting , judo, rugby and athletics. Comodoro Rivadavia

4347-553: Was at one time the capital of the Comodoro Rivadavia Territory, which existed from 1943 to 1955. The territory was a part of Chubut before and after its creation, and the city became the capital of the Escalante Department . It had a population of 137,061 at the 2001 census [ INDEC ] , and grew to 182,631 by the 2010 census. Comodoro Rivadavia is a commercial and transportation center for

4416-719: Was disputed between Chile and Argentina until 1881. Chile renounced its claim in order to prevent Argentina from entering into the War of the Pacific , in which it was already fighting against Peru and Bolivia. As part of the Conquista del Desierto (Conquest of the Desert), Argentina organized the National Territory of Chubut in 1884, after the last indigenous cacique, Inacayal , surrendered to government forces. Luis Fontana

He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy . Later a fourth period, the Quaternary , was applied. In the early development of the study of geology, the periods were thought by scriptural geologists to correspond to the Biblical narrative,

4554-468: Was named governor. At the beginning of the 20th century, after the Boer War , some Boer people settled in the town of Sarmiento and in lesser number in other nearby towns. From 1895 to 1915 hundreds of Spanish and Italian born immigrantes settled in the lower Chubut valley as well a little more than hundred Chileans. In 1944, the southern part of Chubut and northern part of Santa Cruz were designated
