Abstract
LowerCretaceousLeushinskayaandVikulovoformationshaverecentlytestedoilandgasforthefirst
timeintheShaimRegionlocatedinthewesternborderofWestSiberianBasin.Beforethat,these
formationswereknownashydrocarbonreservoirsonlyinKrasnoleninskoyeregion(Kamennoyefield)
wheretheyproduceoilfromVikulovosandstonesandsiltstones[1]Presenceofcommercialgas
accumulationinCretaceoussectioninthispartofthebasinisalsonewasnogasfieldshadbeen
discoveredbefore2013.
TheaimofthispaperispresentingtheresultsofthereservoircharacterizationstudyofLeushinskaya
andVikulovoformationsbasedonnewlogandcoredata.Thedatahasbeenobtainedduringthe
2012–2013drillingcampaignperformedbyEurotekYugra(100%Repsol)inKarabashskiyareain
ShaimRegion.
Asaresultoftheintegrationofcore,thinsectiondescriptionandinterpretationwithloggingand
seismicdata,anewfaciesandsequencestratigraphicmodelofNeocomianAptianreservoirsis
presented.Thismodelprovidesapredictivetoolforassessingthequalityanddistributionofthese
reservoirsinthewesternmostpartofShaimRegion.
