OREANDA-NEWS. Rosneft significantly increased the volume of geological exploration.

Since the beginning of 2015, testing of four exploration wells was completed, a total of 28.5 thousand meters was drilled and the amount of Rub 10.819 bln. was invested in geological exploration operations. Nine seismic exploration projects were completed, including acquisition of 1, 222 line km of 2D seismic and 4,205 sq. km of 3D seismic. As compared to the first quarter 2014, the Company increased the rate of 2D seismic acquisition more than three times, and the rate of 3D seismic acquisition - by 17%.

A total of 11 new deposits with (АВС1+С2) reserves of about 5.5 mln TOE were discovered in the first quarter. Also, as a result of L'nyanaya № 30 exploration well drilling in the Samara Region the field of the same name holding 110 thousand tons of С1 oil reserves was discovered. The field was included in the State Reserve Register in Q1, 2015.

As a result of exploration well testing in Kamelikskiy license, Orenburg Region, gas condensate inflow of over 300 CMPD was obtained, and the field that was given the same name was discovered. Expected С1 reserves addition is 805 thousand TOE, and С2 reserves addition is 733 thousand TOE. The field will be included in the State Reserve Register within 2015.

The Company acquired five licenses in Samara Region, Khanty-Mansiysk and Yamalo-Nenetskiy Autonomous Regions and in the Republic of Inguishetia with (АВС1+С2) reserves amounting to 7.6 mln TOE.

Exploration activity is followed-up by active development of appraised reserves. Successful commissioning of Vstrechnoye field (OOO RN-Yuganskneftegaz) in 2014 is an example of bringing reserves into development. Ten horizontal wells with average flow rate of 352 tpd were drilled at the field. Along with that, the study of the field geology continues. The geological model of the field was updated based on 3D seismic interpretation performed in 2014, resulting in five-fold increase in in-place reserves from 15 to 78 mln tons (С1+С2 reserves) due to extension of deposit boundaries.

The Company has been carrying out planned development of resources in East Siberia, where in the past 5 years it added 412 mln TOE of commercial С1 reserves. In addition to the fields currently under development (Vankor, Verkhnechonskoye field), Severo-Danilovskoe field was put on pilot production in Q1 2015 with naturally flowing wells producing over 200 tpd.

Rosneft is carrying out operations in 51 license areas on the shelf of the Russian Federation. The processing of the following data is currently underway - 79,873 line km of 2D seismic, 14, 243 sq. km of 3D seismic and 235, 099 line km of gravity and magnetic data. Interpretation of seismic data from 20 projects is being carried out, the total volume of the data being: 2D seismic - 134,273 line km, 3D - 3,569 sq. km. Preparations are currently in progress for 2D and 3D seismic acquisition in 10 licenses, and for site engineering surveys in two licenses.

Preparation work for the drilling of Geologicheskaya-1 well in Temryuksko-Akhtarskiy license in the Azov Sea in 2015 as well as for drilling operations in four licenses in 2016, are in progress.
