pdf  Clinoforms as regional oil-gas objects, regularities of their occurrence, forecast of stratigraphic reservoirs in them
The work is devoted to constructing the large scale map of occurrence of stratigraphic reservoirs in submarine fans - clinoforms of the Achimian strata. To date, the regional seismic-stratigraphic interpretation of Neocomian deposits, Tyumen oblast, encompassing 124 standard lists of 1:200000 scale, is performed; 14 clinoforms have been established and mapped. The status of oil-gas megazones, the main units of this territory zoning was first given to them. More than 300 large multibed stratigraphic reservoirs - the new objects of exploration and development - are established in their composition. On the data of CDP-method and drilling their depocenters are mapped, basic parameters are shown, their introduction in exploration and development practice is performed, geographical names are given, petroleum potential is studied.
Key words: West - Siberian Neocomian basin, clinoforms, oil-gas megazones, multibed stratigraphic reservoirs, depocenters, seismics, logging

pdf  Forecast zones of concentration of stratigraphic traps in the Neocomian submarine fans, Surgut district. Petroleum potential and peculiarities of their studying
Six regionally lengthy oil-gas megazones – clinoforms are traced in the Neocomian deposits of the Surgut district. The are the Urievskaya, Mokhovaya, Rodnikovaya, Savuyskaya, Cheuskinskaya, Sarmanovskaya. 85 zones of concentration of stratigraphic traps in the submarine fans of the Achimian stratum are determined in their composition; their depocenters on a parameter of total thickness of sandstones are mapped. The ranking of depocenters by the degree of their exploration maturity is conducted; petroleum potential is studied. This map is a base in choosing the prospective objects for their preparation to detail exploration for the purpose of mapping the concrete stratigraphic traps, re-estimating the resource base and developing hydrocarbon fields
Key words: Surgut arch, oil-gas megazones, depocenters, multiple-bedded stratigraphic reservoirs, mapping of regionally developed clinoforms, petroleum potential.

pdf  Geological structure and conditions of forming the Neocomian reservoirs of the South-Western uplift of the Yuzno-Yagun field
The dissection and correlation (by layers) of the Neocomian БC10-11 productive stratum, South-Western uplift, Yuzhno-Yagun field, Western Siberia, are performed. The model of productive stratum structure and sedimentation is developed on the basis of conventional technique and technology of automatized correlating the well sequences. The ways of optimizing the geological-technological measurements in the productive stratum at the uplift arch are outlined; the forecast resource estimation is made, recommendations for exploration in the margin parts of the South-Western uplift are developed.
Key words: Western Siberia, Surgyt arch, Yuzhno-Yagun oil field, Neocomian, seismic survey, logging, correlation by beds, cycle character, productive stratum, model of structure, clinoforms.
