Strategy of development of an oil-and-gas complex of Siberia

The modern state of an oil-and-gas complex of Siberia is considered in the article. Strategy of development of an oil, gas, oil-and-gas refining and oil-and-gas chemical industry of Russia up to 2035 in view of consequences of world financial crisis is presented. The target indicators of realization of the given strategy are given.

Geological structure features and prospect of development of Romashkinskoye oilfield Givetian deposits

The oil pool pattern of ardatovsky and vorobyovsky horizons of Givetian stage in limits of Romashkinskoye oilfield is given. Commercial oil content in reservoir beds of vorobyovsky, ardatovsky and mullinsky horizons is established. Their lithologic stratigraphic characteristic is considered. The actions, allowing to optimize the development of pools in terrigenous deposits of Givetian stage, are offered.

The efficiency of geological-petrophysical study on the vuggy fractured reservoirs of the crystalline basement oil fields and evaluation of parameters for reserves calculation

Log analysis shows that log responses are practically influenced by various distortions conditions. Evaluation of porosity by log data is complicated due to difficulties in rock identification, its polymineral composition, resulting anomalies in logging  curves. It is noted that identification of dyke intervals, alterated rocks and zones with abnormally high voids is only possible when all geological and log data are available and used in complex. Possibility of using the method of balanced porosity based on corrected data of acoustic, neutron-neutron, density and SGR logs for further application of volumetric method is examined. Possibility of SP curve using for identification massive vuggy-fractured, altered reservoirs on the basement is shown

Dependence of the oil recovery on the well grid density

The theoretical researches, which have confirmed dependence of the oil recovery from the well grid density, are carried out. The received results allow to forecast the expected oil recovery depending on the well grid density, the production of average well and an oil output time.

About anomaly pressure stand-up-curves in case of complexly formatted reservoirs of high viscosity oil by the example of TatRITEKneft NGDU’s oil fields

The subject is the pressure stand-up-curves form evolution during the recovery of high viscosity oil field. Some new – nonclassic – hydrodynamical scheme of geological object to explain anomaly forms of curves is put on discussion. The data gives some basis on new approach to estimate pressure stand-up-curves signification.

Perfection of level recovery curves interpretation methods at wells survey

The problems, connected with wells survey by the level recovery curve method are considered. It is shown, that applied methods of level recovery curves processing by the indicator curve scheme are improper. The technique of level reco - very curves processing on the basis of reference curves is offered. The new variant of reference curves empirical chart with wider range of changing  parameters of a well, a layer and a skin-effect is presented
