In Australia before Montara catastrophy there were 2 oil spills incidents. Australian offshore drilling and offshore exploration sectors demand (Figure 1).
The southeast region of Brazil has been experiencing since summer 2014 a major drought event leading to a number of impacts in water availability for human consumption, agricultural irrigation and hydropower production. As is known, 75% of the electricity generated in Brazil falls on hydroelectric power stations that are located in the channels of the largest rivers, such as Parana, San Francisco and Amazon. Most rivers either dried out or significantly reduced their capacity. In addition to disruptions at the hydropower station, the second largest source of electricity in the country -ethanol, which is made on the basis of sugar cane -suffered. A high percentage of crops due to lack of irrigation [1,2,3]. A quarter of the country's inhabitants had limit access to water. The north-eastern regions suffered so much because of aridity, that the government decided to change the channel of one of the largest rivers of Brazil -San Francisco. Also, several artificial river hoses were assigned to a territory with water shortage. The drought was largely due to the anthropogenic factor. First, in the last few decades, in Brazil, there is a massive urbanization, which entails irrational use of water resources. The felling of trees has significantly increased. Most of the forest goes to building materials and spaces for the new construction of sprawling cities [4,5]. It was also a real hard time for animals (Figure 1).
The geological structure of the Achimov deposit is represented by platform formations of different periodsJurassic, Cretaceous and Paleogene -Quaternary. They lie on the foundation of rocks of pre-Jurassic age [5].The Achimov beds are reservoirs with a very complex distribution of lenticular bodies. In the Achimov deposits, several local reference strata of clays 3-15 meters thick are distinguished. These strata divide the Achimov strata into several independent layers. Lenticular form of sand bodies of the clinoform sequence, their reliable isolation provide a dense package in space, so the potential deposits in such bodies are almost independent of anticlines, but are controlled by the intrinsic morphology of each individual lens and the quality of the collectors and represent rather a layering of a broken or stepped structure [6].The reservoir is characterized by poor and heterogeneous reservoir properties, low permeability, complicated by tectonic and lithological screens, characterized by a multiphase reservoir condition. In addition, the Achimov deposits are characterized by abnormally high reservoir pressure, more than 600 atmospheres, and the presence of heavy paraffin (Figure 1) [2].Here is the plotted geological sector model of the Achimov field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
