Block A in the South Turgay Basin, Kazakhstan, lies in a gentle slope zone of rifted lake basin, where structural traps are not developed, so it is important for explorers to find litho-stratigraphic reservoirs. The drilling records show that, in Block A, lithologic reservoirs are in the Jurassic System, containing 5 formations from bottom to top: Aybolin, Doshan, Karaganshy, Kumkol and Akshabulak. The comprehensive analysis of accumulation conditions shows that the effective reservoir-seal assemblage is the main controlling factor for accumulation. With several geological and geophysical methods, it is concluded that the prospects are lied in central and west parts of Block A.oft-com:office:office" />
