The current state of Neft Dashlary field development and geological field indicators
A.A. AbduyevSince the beginning of Neft Dashlary field development 1833 wells were drilled. Now, 339 wells are in the operating well stock. The daily oil output is 2346 t, water – 1470 m3, gas – 155.2 thsd. m3. The output of oil and water per well are equal to 7.3 and 4.6 t/day correspondingly. The major peak of Neft Dashlary development was observed in 1967, when the operating well stock contained 700 wells and oil production comprised 7416 thsd. t per year. In 1990–1999 oil production decreased from 1076 to 671 thousand t. At present, up-to-date technologies are applied in the drilling and formation stimulation. The last one affects positively the oil and gas development process. Beginning from 2000 the oil production increased from 672 to 840 thsd. t due to the drilling of new wells in V block. For this period, 134 wells were drilled, which comprises 42 % of current stock. The daily output of drilled wells is equal to 1322 t. The residual oil reserves in Neft Dashlary field is estimated at 25 mln t. Conducted geological and technical measures promotes the oil production increase. To these measures is related the water injection too.
