Tatneft's financial results for the first half of 2006 under Russian
Accounting Regulations

18 August 2006

On 11 August 2006 OAO Tatneft  published its financial  statements for the first
half of 2006  prepared  on  unconsolidated  basis  in  accordance  with  Russian
accounting  regulations ("RAR") as a part of statutory issuer's quarterly report
for the second quarter of 2006.

For the first six months of 2006 OAO Tatneft  produced 12 713.7 thousand tons of
oil  (excluding  production  of  subsidiaries  and  affiliated  companies).  OAO
Tatneft's  oil  sales  volume  for the  first  six  months  of 2006 was 13 335.1
thousand tons, including 398.7 thousand tons of purchased oil. For the first six
months  of 2006 OAO  Tatneft's  non-CIS  export  oil  sales  volume  was 5 947.7
thousand  tons,  CIS exports  (primarily  Ukraine - Kremenchug  Refinery) were 2
658.3  thousand tons and domestic sales were 4 729.0 thousand tons. In the first
half of 2006 main  domestic  sales were made to the ZAO  TAIF-NK's  refinery  in
Nizhnekamsk (3 803 501 tons) and to the Moscow refinery (817 926 tons).

OAO Tatneft's  sales  revenues  under RAR for the first half of 2006 were 95 085
237 thousand Russian Rubles, an increase of almost 16% in comparison with 81 879
783 thousand  Russian  Rubles for the same period of 2005. For the first half of
2006 the  production  costs under RAR increased by 13.2% in comparison  with the
same period of 2005 and  constituted  58 193 448 thousand  Russian  Rubles.  OAO
Tatneft's  net  income  under  RAR for  the  first  half of 2006  was 23 435 242
thousand  Russian  Rubles,  an increase of 43%  compared to 16 137 238  thousand
Russian  Rubles of net income for the same period of 2005.  The  increase of OAO
