LUKOIL carries out exploration work in 11 countries around the world.
LUKOIL is investing in prospective regions both in Russia and abroad, preparing
the raw material base for production and ensuring that levels of production
increase rapidly. The Company uses modern technology in its exploration work,
which ensures growing efficiency of exploration. The success rate in prospecting
and exploration drilling by the Group is about 70%.
The Company substantially increased volumes of 3D seismic work
(by 51.3% to 6,523 km2) in 2012 compared with 2011, in order to
identify and detail structures, and to prepare for drilling of prospecting and
exploration wells at promising sites. The volume of 2D seismic was 3,248
Vertical seismic profiling, which details the geological
structure around a well that has been drilled, was carried out at 15 wells in
2012. Exploration drilling increased by 26.5% to 201 thousand meters in 2012 and
a total of 52 exploration wells were completed, of which 36 were
Five new fields were discovered, of which two oil fields in Perm
Region (Provorovskoye and Sukhareva), one oil field in Tatarstan
(Zapadno-Bimskoye), one oil field in Volgograd Region (Dobroye) and one gas
condensate field in Uzbekistan (Shurdarye). A total of 17 hydrocarbon
accumulations were discovered at already known fields.
Most of the increase was from further exploration of fields in
the Northern Caspian and Komi Republic. Organic reserve growth compensated 82%
of hydrocarbon production. Most of the organic growth of proved reserves was in
Russia (613 million boe or 92% of the total).
Largest prospecting projects in 2012
Prospecting and exploration work in the Caspian Sea
The Northern Caspian will be a key region for growth of oil
and gas production by the Company in the medium term, and
LUKOIL is therefore devoting particular attention to the development
of resource potential in the region. Increase of the Company's
proved reserves to international standards in the region during 2012, thanks
to additional exploration, was 109 million barrels (+14.9% to 2011).
Three wells were completed in the Caspian Sea and all of
them were productive, so the success rate in exploration
drilling was 100%.
A first prospecting well was drilled at the
Zapadno-Sarmatskaya structure and confirmed gas presence in Titonian sediments,
which have already been found to be productive at the Yu.
Kuvykina (Sarmatskoye) field. Drilling work began on
Zapadno-Sarmatskaya well ¹ 2. A total 89 km2 of 3D seismic surveying was
carried out at the Sarmatskaya area, and 500 km of 2D survey work was completed at the Severny area for detailing of the Yuzhnaya
and Yuzhno-Shirotnaya structures and to search for a zone of
possible development of non-anticlinal features to the south of
the Yu. Korchagin and V. Filanovsky fields.
Prospecting work in the Denisovskaya Depression (Komi Republic)
A total 23.4 thousand meters of prospecting and
exploration drilling was carried out in the Komi Republic and five
wells were completed, of which four were productive (80%
drilling success rate). Exploration wells ¹ 2 and 4 at the
Vostochno-Lambeishorskoye field were completed and transferred to the
field operator. They are now operating with daily flow rates of
about 600 cubic meters.
Prospecting drilling in the Baltic Sea
LUKOIL carried out exploration work both onshore in
Kaliningrad Region and on the Baltic Sea shelf during 2012. Total drilling
was 6 thousand meters and 100 km of 2D seismic work was
carried out at the Yuzhny license area. Drilling of prospecting well ¹
1 in the Baltic Sea was completed (the distance drilled in 2012
was 4 thousand meters). The well is now being tested. A first prospecting well was also drilled at the
Yuzhno-Volodarovskaya structure (1,930 meters drilled).
Prospecting work in Uzbekistan
At the Kandym block wells Parsankul-9 and Parsankul-10
were completed and testing gave daily gas inflows of 90 thousand
cubic meters and 196 thousand cubic meters, respectively. Preparations were made for 3D seismic data acquisition and 450 km2 of
3D work was carried out. The geological model of the Parsankul field
was updated in 2012 and rapid assessment of C1 hydrocarbon
reserve increment from the new wells was made.
Drilling work was completed in the South-West Gissar
project and well Shurdarye-2 was tested. Testing of Upper
Carbonaceous sediments gave daily commercial inflow of gas and condensate
at rates of 647 thousand cubic meters and 95 tonnes,
respectively, marking discovery of the Shurdarye field.
