The oil and gas industry isas one of the most important economic sectors in Russia. Its development ensures satisfaction of increasing needs in energy resources. The problem of the growth of reserves in the Far East is especially acute at the moment. This region is significantly removed from the main production areas. In 2008, work began on one of the sections of the shelf located on. Sakhalin. In the course of them a relatively small pool was opened. Let us further consider its features.
Yuzhno-Kirinskoye field of Gazprom
As part of the preparatory work was carried outseveral 2D seismic surveys. They allowed the preparation of two large structures, which are connected with elevated blocks from the Mesozoic dislocated basement. In search works on the licensed territory, the South Kirinskoye field was included first. This was due to the fact that during the seismic survey in this area a zone of a significant change in the dynamic characteristics of the roof reflections of the promising main Dagin suite was discovered. Its sandstone beds contain deposits that include the neighboring Kirinskoye gas condensate field. Immediately before the start of exploratory drilling, 3D seismic survey was performed on the whole area of the site.
The first project
Kirinsky deposit was discovered in 1992year. In the autumn of 2013 this section of the shelf was not put into operation. On October 23-26 Miller and Markelov's visit was planned for a formal launch and drafting of a report to the president on the successful work done. The commissioning was planned for the second quarter of 2014.
Description of the territory
The Kirinskoe field is located 28 km from the coastline in the sea. The depth here is 91 m. Initially, the basin's reserves were 75.4 billion m3 gas category ABC1 + C2, and here it is revealed 8.6 million tons of gas condensate. After the conducted in 2009-2010-ies. geological exploration reserves of the territory increased to 137 billion m3 by category C1. At the same time, recoverable condensate deposits amounted to 15.9 million tons.
Underwater mining complexes, the mass of whichabout 400 tons, it was planned to install on the seabed. Each of them must combine two or four production wells. The use of these complexes is considered an innovation. It was planned to be used in the development of the territory for the first time in the country.
Specificity of production
Gas with condensate and water will be sent to thetechnological complex, built on the shore. It is under construction in Nogliki District, 16 km from the coastline. Next, the pipeline will feed raw materials to the main compressor station. It is located in the Botasino area. From there, the gas will go to the main system, and the condensate will go to the existing oil pipeline. The management of the management company and the Government determined the deadline for the implementation of the feedstock supply plan in August 2012. OOO Gazprom-Proychycha Shelf was appointed as the operator of the project.
Implementation of the project
After the disaster that occurred in the power systemJapan, the Russian Government has instructed to speed up the commissioning of the basin. As a result, Gazprom, which previously refused to attract foreign investors, will probably have to turn to foreign partners. In early autumn of 2012 it became known about the backlog from the planned terms in the construction of infrastructure. In this regard, the beginning of raw material extraction was postponed to the 2nd quarter of 2013. After a while it was announced that a new Yuzhno-Kirinskoye deposit was discovered within the study area. The reserves revealed in it were not at that time still put on the balance of the management company. The site found, among other things, 464 million tons of oil. The management company has promised that the raw materials will go to load the third stage of the plant on the island. Its introduction was planned for 2021. It was assumed that the construction of the line will be carried out for 5 million tons.
The South Kirinskoye field in the Sea of Okhotsk wasIt was found after the seismic 3D survey. Its deposits are revealed in the sand layers of the Daginskaya roof. The area of the seismic survey closes the southeast section of the field. It continues to the north-west and west. For the gas-saturated interval, the maximum effective power can reach 160 m, wedging all the way to the arch of the structure to the east. To the south the deposit is limited by a structural trap. The investigated area of the site is broken by low-amplitude numerous tectonic disturbances. However, they do not control the extent of the deposits.
Drilling in the framework of reconnaissanceconfirmed the forecast, which was compiled based on the results of the seismic survey. The first drilled well revealed 2 saturated reservoirs located at the top. Their total thickness was 155 m. Geophysical measurements during the drilling and at its end allowed to obtain the primary petrophysical information for subsequent geoseismic modeling. After the completion of the first stage of prospecting and exploration across the entire territory of the Yuzhno-Kirinskoye field, it will be possible to significantly increase the resource base for the subsequent development of the extraction of raw materials in the Far East.
Yuzhno-Kirinskoye field: sanctions
The US authorities introduced point restrictions ina number of domestic companies. The US government and the Gazprom company did not fail. Various restrictions were imposed on the domestic monopolist. In particular, the US government banned the supply of any products of its own production to the Yuzhno-Kirinskoye field. The restriction applies not only to the supply, but also to the movement of American equipment inside the territory. This means that already purchased equipment can not be delivered to the field to continue development. The US government has decided that export, re-export deliveries, as well as the transfer within the state of any equipment subject to export regulation, to perform work in the basin study area by any person who did not previously agree with the US monitoring structure, will be considered a violation of the imposed prohibitions. The Yuzhno-Kirinskoye deposit was included in the sanctions list, since, as reported in the statements, it has significant oil reserves. In this regard, all the contractors of the management company, associated with American technology, had to abandon the supply.
The introduction of sanctions by America makes it very difficultgeological exploration work in the field. The fact is that its development using underwater mining complexes is unique and based on foreign modern technologies. The US government has found a project that is of particular importance to Gazprom. At the same time, the territory studied by the domestic company is located in the Asia-Pacific region. Here Gazprom acts as an uncomfortable competitor for the American LNG. According to Nesterov, the US thus solves its own strategic tasks. The American government is based on the interests of current politics and conjuncture.
Features of prohibitions
Sanctions against the South Kirinsky depositoperate from August 7, 2015 year. This date is set in the US federal register. It should be noted that these sanctions have previously concerned the domestic mining company. The first restrictions also concerned the supply of high-tech equipment for the oil and gas complex. Then a list with 30 titles was listed.
