The above-the-plan production amounted to 108,508 tons of crude oil (101,7%)  The best results were achieved by NGDUs (Oil and Gas Production Boards) Elkhovneft (104.5%), Yamashneft (102,9%), and Leninogorskneft (101,8%). The amount of 2,120,240 tons of crude oil was delivered by the first quality group.

The plan of drilling meterage for the first quarter of 2007 was executed by 108,5% with 210,7 thousand meters penetrated, including 140 thousand meters (116,9 %) for OAO TATNEFT, 70 thousand meters for Joint Ventures and small oil companies and drilling to the bitumen - 700 meters. 131 wells were constructed and handed over to customers including 70 wells (106,1% to the plan) for OAO TATNEFT, 60 wells for Joint Ventures and independent oil producing companies and drilling to the bitumen - 1 well.
Well drilling operations with application of traditional drilling techniques were performed by 52 drilling crews. Two crews performed drilling into the producing layers in the balanced pressure mode and in the mode of underbalanced drilling (UBD). Tree drilling crews performed drilling operations outside the Republic of Tatarstan with 2 of them operating in Samara District and one crew operating in Orenburg district. One drilling crew performs drilling to the bituminous deposits for NGDU Nurlatneft at Ashalchinskoe bituminous field.
There were six drilling crews performing works in the old well stock doing sidetracking jobs while additionally one crew operated on a subcontracting basis. One crew performs the workover job at well No. 200 Rubezhenskaya in Orenburg District with application of K 100 workover unit. This method (horizontal wellbore drilling and sidetracking) allowed penetrating 5,117 meters with 16 well handed over to the customers for operation. Penetration per drilling crew for the first quarter amounted to 3,831 meters.

846 well remedial works were performed during the month of March while 2,464 workovers were performed from the beginning of the year. Shortages in crude oil production due to the well remedial works and subsurface equipment repairs amounted to 58,4 thousand tons (6,8% reduction versus the similar period of 2006). 646 wells were worked over (222 wells in March) including 155 workovers with application of coil tubing units (51 wells in March) and 34 of them were worked over through the annulus (14 wells in March). In addition 13 services (5 wells in March) were rendered in performing traditional workovers including 1 well for OOO Tatneft-Takaral. Formation hydrofracking operations were performed at 26 wells (5 wells in March). Cumulative incremental crude oil production volume amounted to 1,343 thousand tons of crude oil. Additionally one acid hydrofracking operation was performed for the outside company (OAO RITEK). Works on oil recovery enhancement were performed at 556 wells (194 wells in March) including chemical treatment methods applied at 356 wells (120 wells in March). The additional crude oil production through application of oil recovery enhancement methods amounted to 1 million 242 thousand tons (109% to the plan) with chemical methods accounting for production of crude oil in the amount of 585 thousand tons (47% of the total incremental crude oil production volume through application of the oil recovery enhancement methods).

Neftechimservice Company produced 7 thousand 193 tons of chemical products for the amount of 134 million rubles including 2,072 tons of chemicals for outside companies.
Radial drilling projects were implemented at 16 wells by OOO RV-Plast Company including 12 wells for OAO TATNEFT (10 wells for NGDU Nurlatneft, 2 wells for NGDU Elkhovneft) and 4 wells for outside companies (3 wells for ZAO TatRITEK, 1 well for OAO Udmurtneft). The cumulative incremental crude oil production volume through application of radial drilling amounted to 100 thousand 156 tons.
