Resumen
It is generally agreed that a couple of years after Cabral's discovery of Brazil in 1500, the Portuguese Crown leased out the land to a trading consortium for economic exploitation and further exploration. But whether the Crown granted one or two leases, and when the second lease [if there was one] began and for how long it ran, have long been matters of confusion and disagreement.Evidence of the first lease is clear. A letter of Rondonelli written from Seville and dated the third of October, 1502, speaks of a three-year lease on the following terms: the consortium would have to send six ships

Resumen
Global experience in oil exploration and the discovery of the Tupi field in Brazil and the Tiber field in the Gulf of Mexico in the last decade have confirmed the existence of giant oil fields with abnormally high formation pressures at depths of 10 km or greater. Until recently, the discovery of large oil accumulations in deeply buried reservoirs was considered as theoretically impossible. This work suggests that giant oil accumulations at great depths (6–10 km) should be considered important hydrocarbon exploration targets in the Russian Federation and the countries of Eurasian Economic Unio

Resumen
With the discovery of the Pre-Salt reserves, exploration of oil and gas is being strongly extended in Brazil, contributing to the recent increase of the demand for drilling capabilities. This paper discusses the impact of this oil discovery by assessing the relationship among the growth of proven reserves, the financial position of firms, and patent applications in the Brazilian upstream oil and gas industry. We provide empirical evidence indicating that firms with a lower financial performance prior to the pre-salt discovery were more aggressive in increasing the number of patent filings addr

According to the demands of energy saving and carbon emission reduction, the water vs. energy nexus has become a major concern worldwide. Brazil occupies a singular position in the global energy system. A major portion of the Brazilian occupancies has electricity and the energy system expansion that, at first, possesses adequate means for supporting the economic growing may experience some turnovers.

Shell Discovers More Oil Off Namibia Shell announced its oil discovery off Namibia in January and was “very encouraged by the early results” from the Graff-1 exploration well in the country’s Orange Basin, which “established a working petroleum system and the presence of light oil.” Researchers at Wood Mackenzie believe the find could hold upward of 700 million BOE. Shell is currently drilling a second well at La Rona, an aggressive stepout which is likely to be appraising the discovery prior to confirmation of a potential commercial development.

Central to Paulmier’s argument was the extract from a document purporting to be the travel account of a sixteenth-century navigator, Gonneville. The extract details how the unknown land was discovered after the navigator’s ship L’Espoir had lost its way and landed in the fabled Terres australes, south-east of the Cape of Good Hope.

Shell’s Namibia Wildcat Encounters Light Oil Supermajor Shell has struck light oil with its Graff-1 exploration well offshore Namibia, according to the country’s national oil company, a partner in the probe. The National Petroleum Corporation of Namibia (Namcor) confirmed the discovery. Partners in the Orange Basin well included Shell Namibia Upstream and QatarEnergy. The probe was located about 270 km away from Oranjemund, and was drilled to a total depth of 5376 m in water depths of 2000 m. The drilling operations on Graff-1 utilizing the Valaris DS-10 drillship began in early December 2021

The world’s main tantalum (Ta) resources are in pegmatites (e.g. Wodgina, Australia), rare element-enriched granites (e.g. Abu Dabbab, Egypt), peralkaline complexes (e.g. Nechalacho, Canada), weathered crusts overlying the previously mentioned deposit types, and in placers. Niobium (Nb) resources with the highest economic potential are in weathered crusts that overlie carbonatite complexes (e.g. Catalão I and II, Brazil). Brazil accounts for 90% of the global Nb mine production with another 9% coming from the Niobec Mine, Canada (a hard-rock underground mine). However, at least 17 undeveloped

The year 2023 marks the thirty-fifth anniversary of botanical artist Margaret Mee’s final expedition to the Amazon. On this trip, she was at last able to paint the rare night-flowering of Selenicereus wittii, commonly known as the Amazon moonflower. Such an accomplishment was not only significant due to the rare nature of the event, but also because it was the final piece created by an artist who renewed the practice of botanical painting. Originally from Britain, Mee lived in Brazil for more than thirty years, embarking on fifteen expeditions to the Amazon region between 1956 and 1988, painti

Resumen
Natural hydrogen is green hydrogen that is naturally produced on Earth, that is, an energy source that does not emit carbon without using additional energy for production. Since carbon is emitted from the existing gray hydrogen and blue hydrogen, green hydrogen with perfect eco-friendliness has been required. Natural hydrogen is produced through four mechanisms: serpentinization, radioactive decomposition, magma gas removal, and rock destruction and can exist in the dissolved ․ content of fluid mammals. Representative sites discovered to date include Mali, Africa, Brazil, and Australia, and ea

_ A gold strike was announced in late October. But in this case the gold was naturally occurring hydrogen in a former coal basin. Known as “white” or “gold” hydrogen, the reported discovery of naturally formed underground hydrogen was made in northeastern France’s Lorraine coal basin, a region between France and Germany. The last coal mine was shut down 20 years ago. Researchers at the French National Centre of Scientific Research (CNRS) were testing a probe designed to analyze gases dissolved in the water of deep underground rock formations, looking for methane, when they detected hydrogen co

Regardless of the direction of development and changes in the energy sector, the Worlds economies will rely primarily on natural resources for at least the next 20 years and very likely beyond. Actually, the resources of hydrocarbons in place in comparison with consumption are almost inexhaustible, so the question is only in the cost of production. For this reason, the exploration for new commercial fields that can withstand price volatility over a long period of time will play a critical role.

Things have changed for operators looking to forward multibillion-dollar megaprojects in the GOM.

Historians of colonial Brazil have conventionally located the conclusion of the great era of bandeira-led conquest somewhere near the end of the seventeenth century. The onset of the colony's gold cycle, corresponding with a series of major inland mineral strikes, reoriented those most actively engaged in the bandeira enterprise. Concentrated in the southern coastal captaincy of São Vicente, later, São Paulo, these wilderness adventurers had explored Portuguese America's immense interior and hunted its indigenous inhabitants.
