Rosgeo continues to interpret the exploration results of Bering Sea

In the third quarter of 2019, Dalmorneftegeofizika, OJSC (city of Yuzhno-Sakhalinsk, the company is a part of Rosgeo State Holding) will interpret the seismic data of 1,000 running km obtained from the exploration of geological structure of the slop deep water of Komandorsky and Aleut Sedimentary Basins in the Bering sea. The exploration is performed to assess the prospects of oil and gas potential of the area under the state contract concluded between the Holding and the Department for Subsoil Use in the North-Western Federal District, on the continental shelf and in the World Ocean (Sevzapnedra). The works are financed from the recourses of the federal budget.

In 2018 Dalmorneftegeofizika, OJSC, performed a great amount of exploration work at the site with CDP seismic reflection method with the help of Academician Fersman seismic vessel. Sankt-Peterburgskoye morskoye geologorazvedochnoye podrazdeleniye, OJSC (the company is also a part of Rosgeo) was performing the gravity and magnetic exploration at the same time.

In the second quarter of 2019, based on the results of office studies, Dalmorneftegeofizika’s specialists conducted the lateral interpretation of 1,093.67 linear km in total.

The key 1, 2, 3, 4, Fa seismic level reflectors were allocated in the sedimentary cover of the Aleut and Komandor Sedimentary Basins, the correlation of which will allow to define the structural plan of sedimentary basins and rearrange their evolution. Moreover, in seismic sections there were allocated 1', 41 auxiliary markers, which allow to specialize the structure of seismic zones and opal-A/opal-CT lithogenetic boundaries, giving a perspective of the thermal regime of the basins and showing that there is a siliceous and terrigenous composition of the sediments. An information geological report on the work results performed in the course of the reporting period was prepared.

The interpretation of seismic data will be continued in the 3rd quarter.

It is planned to complete the exploration of a sedimentary basin until the end of 2019. The work should result in the assessment of localized hydrocarbon resources and the provision of recommendations to perform further stages of geological exploration in order to reproduce the resource base of hydrocarbon raw materials.

Rosgeo is a Russian multi-industry geological parent company, which renders a full range of services related to geological exploration, i.e. from areal studies to stratigraphy and subsoil monitoring. The parent company has distinctive competencies, in particular, in the field of marine geology and offshore operations. Rosgeo was founded according to RF President’s Decree No. 957 of July 15, 2011 based upon one of the oldest exploration companies in Russia – Tsentrgeologiya.

The parent company’s enterprises operate in all eight Federal Districts of Russia.

Dalmorneftegeofizika (DMNG), OJSC, was established in 1965 to conduct the oil and gas prospecting works on the shelf of the Far East of Russia. During the half-century period, DMNG conducted hundreds of thousands of kilometers of seismic works as well as a large amount of gravity and magnetic exploration. The company managed to set and solve a number of major tasks of national importance. Constant modernization of the seismic fleet, computer center and geological survey allows DMNG to strengthen its position in the global marine seismic market, meeting the highest standards and requirements of the oil industry. DMNG was transferred to Rosgeo State Holding among other exploration enterprises by decree of the RF President No. 81 dated February 19, 2015.
