“…Allen et al, 2010). Sedimentation was broadly affected by local as well as regional fault systems which were later reactivated at various times (Oglesby, 1987;Lefever et al, 1987;Greggs and Greggs, 1989;Gerhard et al, 1991;Pu et al, 2003;Dixon, 2008). In southeastern Saskatchewan the basement is thought to have been dissected by a series of lineaments or faults dominated by an orthogonal NW−SE and NE−SW orientation (Potter and St. Onge, 1991;Kreis and Kent, 2000;Nimegeers and Haidl, 2004).…”

The Yeoman and Herald formations of the Late Ordovician Red River succession of southeastern Saskatchewan comprise two carbonate-evaporite cycles in the epicontinental Williston Basin. Although these units possess an overall 'layer-cake' aspect across a broad area, thickness variations in the Herald Formation show that accumulation was affected by syndepositional flexure, differential subsidence, and displacement of basement faults thought to have been oriented orthogonally NE−SW and NW−SE. The dolomudstones and anhydrites of the Lake Alma and Coronach members host a variety of synsedimentary deformation features -seismites-interpreted to have been induced by earthquakes generated by movements of these faults, and the low-energy, subaqueous environmental setting was conducive to their preservation.Individual deformed intervals are <0.2 m thick. Folds and small-scale pinchand-swell structures indicate plastic behaviour of both carbonate and evaporite sediment under compression and shear stress. Brittle failure of stiffer material from compression or extension is shown by microfaults, cracks, disrupted layers, pseudo-intraclasts, breccias and cataclastites. Dikelets in interlaminated dolomudstone and anhydrite record cyclically elevated pore pressure that caused dewatering and shrinkage with concomitant fluidization and injection of carbonate mud and primary granular gypsum. Enterolithic anhydrite exhibits compressed vertical dikes that likely represent injection of granular gypsum. Clay-filled shearvein arrays occur rarely in dolomudstone. Seismites are absent in bioturbated limestones except for one horizon of molar-tooth structure.The different kinds of seismites are related to the varying rheology caused by the primary nature of the carbonate and evaporite sediment plus modifications due to deformation-induced dewatering, early diagenesis, and confinement under shallow burial, as well as earthquake magnitude. A minimum shaking intensity of MM=VI was probably required, meaning that events of lesser magnitude were not recorded. Some seismite-bearing horizons can be correlated across the study region. Within the limitations of core control, their geographic distribution varies, probably in relation to the basement faults. Seismites thus serve as proxy signals of syndepositional tectonic activity but also point to components of the basement structural fabric that, if reactivated later, might induce fracture porosity or influence subsurface fluid flow. Syndepositional tectonism undoubtedly had a much more profound influence on many successions than is presently thought, and its effects are more widespread than currently appreciated.

“…The lower two-thirds of the Yeoman Formation lack sufficient porosity and permeability to be considered a good reservoir unit. The uppermost third, which is known as the Upper Yeoman, is strongly mottled, sufficiently porous and permeable to form good quality reservoirs (Kendall, 1976; Kreis and Kent, 2000; Pu et al., 2003). Furthermore, the thin, commonly laminated, organic-rich interbeds (kerogenite or kukersite) within the Upper Yeoman are identified as the main source of petroleum in Red River reservoirs throughout the Williston Basin (Derby and Kilpatrick, 1985).…”

This paper presents a new approach, called optimized fuzzy Preference Ranking Organization METHod for Enrichment Evaluation (PROMETHEE), based on combining fuzzy logic, an outranking method and the cuckoo search optimization algorithm to assess petroleum potential in a spatial framework. The approach brings together flexibility and simplicity to solve petroleum exploration problem under uncertainty using experts’ knowledge and the information associated with the discovered oil pools simultaneously. The characteristics of the essential elements of the petroleum system are used as key criteria in the model. To exemplify the approach, a case study was undertaken in the Red River petroleum system of the Canadian portion of the Williston Basin. Eight datasets related to the selected criteria were integrated by the optimized fuzzy PROMETHEE to create a map that makes it possible to identify the areas of highest petroleum potential. All discovered oil pools in the Red River petroleum system were used in the verification process. The results indicated that the proposed approach can deal effectively with incomplete data and imprecise information, and can be efficiently used in petroleum exploration, thereby reducing the cost and risk of exploration.

“…The uppermost third of the Yeoman Formation or Upper Yeoman is strongly mottled, commonly porous, and permeable. These have resulted in relatively good reservoir properties [43,44]. The Upper Yeoman also contains widely distributed, commonly laminated, relatively thin organic-rich interbeds, which are known as kukersites.…”

An inevitable aspect of modern petroleum exploration is the simultaneous consideration of large, complex, and disparate spatial data sets. In this context, the present article proposes the optimized fuzzy ELECTRE (OFE) approach based on combining the artificial bee colony (ABC) optimization algorithm, fuzzy logic, and an outranking method to assess petroleum potential at the petroleum system level in a spatial framework using experts’ knowledge and the information available in the discovered petroleum accumulations simultaneously. It uses the characteristics of the essential elements of a petroleum system as key criteria. To demonstrate the approach, a case study was conducted on the Red River petroleum system of the Williston Basin. Having completed the assorted preprocessing steps, eight spatial data sets associated with the criteria were integrated using the OFE to produce a map that makes it possible to delineate the areas with the highest petroleum potential and the lowest risk for further exploratory investigations. The success and prediction rate curves were used to measure the performance of the model. Both success and prediction accuracies lie in the range of 80–90%, indicating an excellent model performance. Considering the five-class petroleum potential, the proposed approach outperforms the spatial models used in the previous studies. In addition, comparing the results of the FE and OFE indicated that the optimization of the weights by the ABC algorithm has improved accuracy by approximately 15%, namely, a relatively higher success rate and lower risk in petroleum exploration.
