Analysis of Neft Dashlary field development some indices
B.Yu. HumbatovBrief geological characteristic of Neft Dashlary oil field is given. Distribution of accumulated production and residual extracted oil resources in percents from identical indices, characterizing the field as a whole within each block and by section and by area is considered. Block chart of the main development indices, such as initial and residual oil resources, annual (for 2008) and accumulated oil production, incremental oil owing daily production rate of the wells, designed and current oil recovery, characterizing productive possibilities of each block separately and as a whole by field is composed. During 60 years period of development change at time of annual oil production, water-oil ratio, operating and injection wells stock, average daily production rate for 1 well, current oil recovery depending on initial balance oil resources , approved for the last time in 2004, initial recoverable oil reserves usage factor, process of water, injection, etc. is analyzed. It is shown that value of residual recoverable proved reserves by category A+B in comparison with proved reserves, estimated at reserves audit on western standards is decreased only to 14%, that shows high proved reserves that are on state balance. In this connection, it is planed to drill from platforms built during last year some 28 more wells in the nearest time, and to construct platforms no.2521, 755 and others, as well, and to solve a number of technical matters connected, with the system of water injection, construction, etc, that as a whole permits somewhat to increase and stabilize oil production volume on Neft Dashlary field, characterized by relatively high residual recoverable oil reserves by separate formations especially within blocks V and VI.
