Estimation of perspectives of Garadagh field Miocene sediments on the basis of geological-field data analysis

The structural-tectonic features and the results of the analysis of geological-field research of Garadagh field Miocene sediments are reviewed. The oil pool revealed on the north wing of Garadagh structure in Miocene sediments is complicated by breaks and refers to difficulty extracted according to physical- chemical parameters and collector characteristics. As it is known, I and II Miocene sand horizons are submitted by interlacing clay-bearing beds and collectors, the thickness of which is insignificant. The abnormal high formation pressure in these sand horizons exceeds the conditional hydrostatic pressure for more than 1.5 times, that causes high drawdown while development. This is one of the main reasons that results in great problems both while development Miocene horizons and the further operation period. The development of productive Miocene horizons depends on creation of low drawdown and wellbottom zone cementing via known methods. Thus, systematization and analysis of real data allowed to clarify the geological structure and estimate oil and gas bearing capacity perspectives of Miocene sediments in considered area.
