“…The contact between the lower and upper point bar generally dips in the direction of the lateral or downstream growth of the point bar ( Fig. 4a) (e.g., Smith, 1985;Wood, 1989;Wightman and Pemberton, 1997;Hubbard et al, 2011). The proportion of upper point bar versus lower point bar deposits increases in progressively younger point bar layers, resulting in a wedge shaped geometry of the lower point bar deposits (Fig.…”

“…Certain palynomorphs are very useful for age dating and/or correlating sedimentary horizons, for determining depositional environments, including differentiating terrestrial from marginal marine environments. An excellent example has been provided by Hubbard et al (2011), who used palynology for the correlation of strata in a heavy oil deposit (Fig. 3.19).…”

“…Since it was presented for the first time in the 1990s (Zeng et al 1998a, b), seismic sedimentology has been improved in theory and methodology by many researchers and is playing an increasingly important role in oil and gas exploration and development (Posamentier 2002;Miall 2002;Zeng and Hentz 2004;Zhang et al 2007;Zhu et al 2009;Zeng 2010;Reijenstein et al 2011;Hubbard et al 2011). Early seismic sedimentology research mainly focused on discussions of the cases and workflows of overseas marine basins (Kolla et al 2001;Hentz and Zeng 2003;Zeng and Hentz 2004;Loucks et al 2011) and established two key techniques: 90°phase shifting of seismic traces and strata slicing (Zeng 2011).…”

In contrast to marine deposits, continental deposits in China are characterized by diverse sedimentary types, rapid changes in sedimentary facies, complex lithology, and thin, small sand bodies. In seismic sedimentology studies on continental lacustrine basins, new thinking and more detailed and effective technical means are needed to generate lithological data cubes and conduct seismic geomorphologic analyses. Based on a series of tests and studies, this paper presents the concepts of time-equivalent seismic attributes and seismic sedimentary bodies and a ''four-step approach'' for the seismic sedimentologic study of continental basins:Step 1, build a time-equivalent stratigraphic framework based on vertical analysis and horizontal correlation of lithofacies, electrofacies, seismic facies, and paleontological combinations;Step 2, further build a sedimentary facies model based on the analysis of singlewell facies with outcrop, coring, and lab test data; Step 3, convert the seismic data into a lithological data cube reflecting different lithologies by means of seismic techniques; and Step 4, perform a time-equivalent attribute analysis and convert the planar attribute into a sedimentary facies map under the guidance of the sedimentary facies model. The whole process, highlighting the verification and calibration of geological data, is an iteration and feedback procedure of geoseismic data. The key technologies include the following: (1) a seismic data-lithology conversion technique applicable to complex lithology, which can convert the seismic reflection from interface types to rock layers; and (2) time-equivalent seismic unit analysis and a timeequivalent seismic attribute extraction technique. Finally, this paper demonstrates the validity of the approach with an example from the Qikou Sag in the Bohai Bay Basin and subsequent drilling results.
