Another way of increasing production efficiency is drilling of horizontal wells, which increase productivity
by several times and thus raise capex efficiency. Drilling-in of strata at depressions is
another useful technology of production drilling, giving increase of well productivity by 1.3 times on
average.
Well workovers gave additional daily production of 18,317 tonnes in 2005 (3% more than in 2004).
Overall production volumes added by these operations were 4.6 million tonnes, and the economic
effect was $470 million.
The Company continued work on a multi-level system for monitoring of field development using geological-technological
models in 2005. LUKOIL-Western Siberia is developing mini-projects, which optimize
development of priority sectors of large fields using such models.
