pdf Petrophysical properties of petroleum bearing rocks and their oil and gas prospects of a structure affected by an active mud volcano phenomenon (South Caspian basin)
The features of spatial changes in the lithological composition and reservoir properties of rocks of the productive strata (Lower Pliocene) of the Lokbatan gas-oil field of the South Caspian basin, affected by the most active mud volcano of the same name, are considered. On the example of the "Discontinuity" unit of the productive strata (VIIa and VII levels), the dependences between the lithological-reservoir properties and the initial oil flow rates of wells are considered. A positive relationship was found between well productivity and rock porosity.
It has been established that less favorable lithofacies conditions and reservoir properties of rocks are noted near the development of a mud volcano, which are manifested by relatively low productivity of wells. Wells located near faults are characterized by the highest productivity. Due to the low gas content of the field and the absence of the influence of numerous mud volcano eruptions on the productivity of wells, it was concluded that the role of its channel in the migration of hydrocarbons and the formation of the field is not significant.

Keywords: productive strata, lithological composition, reservoir properties, oil flow rate, mud volcano, Lokbatan gas-oil field, South Caspian basin.

pdf  Pecularities of gas content change in productive series belonging to Apsheron Archipelago, Azerbaijan
Based on the data on the change in a wide range of gas-oil ratio GOR values of the Apsheron Archipelago petroleum deposits, the gas content of the productive stratum of the Lower Pliocene and its variation in space are estimated.The value of GOR increases towards the central deep-seated part of the South Caspian Basin. Low GOR values in the depth interval up to a kilometer are due to poor gas conservation conditions.In the stratigraphic section of the productive series, the highest values characterize the different levels of the Balakhani Formation, and the lowest of the Fasil Formation. The characteristic dependence of GOR on thermodynamic parameters, oil density, and capacitive-filtration properties of rocks was revealed.

Keywords: oil and gas fields, GOR, Lower Pliocene, Apsheron Archipelago, Azerbaijan.

pdf  Analysis influence of the reservoir lithofacial heterogeineity of the operating mode of the underground gas storage Galmas (Azerbaijan)
In the paper analyzes of the monitoring results of the operational parameters of the Galmas underground gas storage, created in the same-named depleted gas-condensate field of Azerbaijan is given. The object of gas storage is the terrigenous rocks of the Lower Pliocene age - the Productive series. The generalization of the results of the executed studies allows to conclude that in the operation mode of the Galmas underground gas storage, along with technical and technological, there are certain geological problems associated with the spatial heterogeneity of the lithological composition of the rocks and its capacity-filtration features.

Keywords: underground gas storage, lithofacial heterogeneity, capacity-filtration feature, injection and extraction of gas, depleted gas condensate field Galmas, Azerbaijan.
