Biodegradation of Aromatic Hydrocarbons in Petroleum Reservoirs
Authors A. Ahsan and D. A. KarlsenBiodegradation is just one of the several secondary processes that can alter petroleum composition (Milner et al., (1977). The extent of the process is generally assessed by the degree of removal of different compound classes and individual compounds.

Implications of Rock Criticality for Reservoir Characterization
By S. CrampinThere is mounting evidence that the fluid-saturated stress-aligned intergranular microcracks present in almost all rocks are geometrically close to the critical state where small-scale changes may have significant large-scale effects even at considerable distances.

Sequence Stratigraphy and Stratigraphic Modelling - Application to Lithofacies Prediction, Offshore NE Bulgaria
Authors A. Simeonova, G. Gorin and W. LeuThe Black Sea Deep Basin is of extensional origin and has evolved quite differently from the surrounding thrust belts. The Late Mesozoic-Tertiary deformations within the folded domains have affected anly the marginal areas of the basin. Thus the stratigraphic record onshore and in the area of the present-day shelf is of very limited use for predicting lithostratigraphic patterns in the deep basin. Recent studies on the geological evolution of the Western Black Sea Basin are largely regional and the detailed depositional history of the present-day outer shelf, slope and basin floor is poorly constrained.

The Scope for Horizontal Infill Drilling between Vertical Wells in Oil Rim Reservoirs
Authors D. E. Van Bourgonje and K. J. WeberProducing oil rim reservoirs with vertical wells will always leave significant lenses of remaining movable oil as a result of cusping and coning. Sidetracking of existing wells into these oil lenses appears attractive if the recoverable reserves are sufficiently large.

Mobile Oil in Mature Layered Oil Reservoirs with Low Kv and Large Contrast between Layer Permeabilities

Evaluation of the Economic Potential of Horizontal Sidetracks into Fault Related Attic Oil Configurations
Authors A. Verweij and K. J. WeberOil fields bounded or intersected by faults will always show gaps between the faults and the nearest wells (Martins, E.J. et al, 1993). One reason is the difficulty of determining the exact position of faults.

Types of Hydrocarbon Traps within Sedimentary Cover of the Caspian Sea - Seismic Data Review
Authors Y. P. Malovitsky, B. V. Senin and O. G. TveitenSeismic exploration of the sedimentary cover in the Caspian Sea has been taking place for than 50 years. During that period more than 300 local highs and other traps have been identified here. Some 180 of them are located in the Southern Caspian, the rest are equally distributed in the Middle and North Caspian.

Basin Formation and Evolution Modelling on the Base of Geological-Geophysical Data
By V. SvalovaFor simulation of sedimentary basins formation and evolution the hierarchical mechanical-mathematical multi-layer models of high-viscous fluid were used. Physical parameters of medium (viscosity, density, thermal conductivity) were changed from one layer to another. The problems were solved by computer and analitically under different boundary conditions by asimptotical methods of distribution on small parameters and consecutive approximations.

The Correlation of the Middle Pliocene Sediments within the Apsheron Pre-Balkhan Uplift Zone, South Caspian Basin
More LessThe Middle Pliocene deposits of the Neogene are widely developed covering all of the offshore South Caspian Basin, such adjacent onshore areas as Kura depression, Wester Turkmenistan, Apsheron and Cheleken peninsulas, and southern portion of the Tersk-Caspian trough. In each of these areas, the Middle Pliocene formation has different lithological structure and mineralogical composition, due to the difference in tectonic intensity and orientation, depositional environments and sources of clastic sediments.

About the Criteria of Search of the Deep-Seated Oil and Gas Deposits in South Caspian Basin (SCB)
More LessIt is well known that the criteria of search of the oil and gas deposits for the studied depths (averagely up to 3-4 km) are the presence of massive thickness of the sedimentation, of favourable structural-tectonic traps, of rocks-reservoirs capable to contain the industrial oil and gas, accumulation and reliable caps for the deposits conservation from its further destructions.
