Although studies concerned with the relationships between palynofacies and sequence stratigraphy in several different depositional settings had been published earlier (Pasley & Hazel 1990, Gregory & Hart 1992Powell et al 1992;Blondel et al 1993;Jones et al 1993).…”

Quantitative palynological and palynofacies analyses allow the Lower Jurassic succession of the Dorset coast (Wessex Basin, southern England, UK) to be placed within a genetic sequence stratigraphic framework. The multifaceted approach employed utilizes various palynological criteria adopted from previous publications (e.g. both relative and absolute particle abundance data, allochthonous versus autochthonous palynomorphs ratios, phytoclast type, etc.), and suggests new parameters which may be studied in this context (e.g. ratios of acritarch spine length). Interpretation of palynofacies trends within the studied succession enables the identification of eight genetic sequences informally described as Genetic Stratigraphic Sequences I-VIII. Genetic stratigraphic sequence boundaries are placed at the following horizons: Mongrel, Grey Ledge, Pavior, the Coinstone, Hummocky, the Belemnite Stone, Day's Shell Bed and the margaritatus Stone.These results compare well with sequence stratigraphic frameworks for published for the British Lower Jurassic interval both in Dorset and elsewhere, suggesting that the maximum flooding events recognized are likely to have been of inter-regional extent.

The key obstacles to the development of the four wells in the Pariwali Block of the Potwar Basin in Pakistan continue to be an accurate age diagnosis of the reservoir intervals, facies variation, and locating the hydrocarbon target for future development wells. The purpose of this work is to offer integrated biostratigraphic, facies, and sequence stratigraphic information from well cuttings in order to more fully characterize the carbonate reservoirs. The diagnosis of exact stratigraphic units, their ages, and order of cyclicity were constrained by larger benthic foraminiferal biostratigraphy, and the facies integration has made it possible to identify the sequence stratigraphic architecture. The Paleogene Lockhart, Sakessar, and Chorgali Formation were diagnosed, which were deposited on a ramp carbonate platform in a range of environments, including tidal ats, the inner ramp, the proximal middle ramp, and the outer ramp. The Transgressive Systems Tract and the Regressive Systems Tract, which make up a third-order cycle, were validated by the Lockhart, Sakessar, and Chorgali Formation in the Potwar-5, 2, and 7 wells. The facies correlation of the Potwar-2, 4, 5, and 7 wells shows a distinct vertical and lateral change. The occurrence of LBF wackestone-packstone facies possesses excellent reservoir rock characteristics as seen in the Potwar 2, 4, and 5 wells. The poor reservoir intervals are indicated by the lime mudstone facies and their absence in the Potwar-2, which may have contributed to optimal hydrocarbon recovery. The repetition of lime mudstone facies has caused the reservoir compartmentalization in Potwar 4 &7 wells.
