“…The juxtaposition of marine rocks (Notikewin) above the Falher indicates the presence of a transgression surface, and Schmidt and Pemberton (2003) showed that a transgressive systems tract, bounded below and above by a transgression surface and a maximum flooding surface respectively, can be mapped using core and logs in an area immediately west of our study area. We identified their stratigraphic units in our data.…”

Characterization of stratigraphic sequences (T-R cycles or sequences) included outcrop studies, well log analysis and seismic reflection interpretation. These studies were performed by researchers at the University of Alabama, Wichita State University and McGill University. The outcrop, well log and seismic characterization studies were used to develop a depositional sequence model, a T-R cycle (sequence) model, and a sequence stratigraphy predictive model.The sequence stratigraphy predictive model developed in this study is based primarily on the modified T-R cycle (sequence) model. The T-R cycle (sequence) model using transgressive and regressive systems tracts and aggrading, backstepping, and infilling intervals or sections was found to be the most appropriate sequence stratigraphy model for the strata in the onshore interior salt basins of the Gulf of Mexico to improve petroleum stratigraphic trap and specific reservoir facies imaging, detection and delineation.The known petroleum reservoirs of the Mississippi Interior and North Louisiana Salt Basins were classified using T-R cycle (sequence) terminology. The transgressive backstepping reservoirs have been the most productive of oil, and the transgressive backstepping and regressive infilling reservoirs have been the most productive of gas.Exploration strategies were formulated using the sequence stratigraphy predictive model and the classification of the known petroleum reservoirs utilizing T-R cycle (sequence) terminology. The well log signatures and seismic reflector patterns were determined to be distinctive for the aggrading, backstepping and infilling sections of the T-R iv cycle (sequence) and as such, well log and seismic data are useful for recognizing and defining potential reservoir facies.The use of the sequence stratigraphy predictive model, in combination with the knowledge of how the distinctive characteristics of the T-R system tracts and their subdivisions are expressed in well log patterns and seismic reflection configurations and terminations, improves the ability to identify and define the limits of potential stratigraphic traps and the stratigraphic component of combination stratigraphic and structural traps and the associated continental, coastal plain and marine potential reservoir facies.

“…The Notikewin Member had previously been described as a barrier island complex that had prograded as much as 150 km, although modern barrier islands generally form in transgressive environments. Schmidt & Pemberton's (2004) work demonstrated, however, that the barrier deposits formed in Notikewin time did not prograde a great distance as a barrier island/lagoon complex; instead sandstones and conglomerates of limited lateral extent were deposited in an orientation that was approximately parallel to the shoreline. The most prolific Notikewin Member wells occur in a narrow east -west trend through Township 67 from ranges 8 to 13W6.…”

“…Notikewin Member Schmidt & Pemberton (2004) state that the Notikewin Member is the youngest member of the Spirit River Formation, and is underlain by the Falher and Wilrich Members, respectively. During deposition, the Western Canada Foreland Basin was inundated by the Boreal Sea, resulting in the formation of a shallow epeiric seaway.…”

“…The most prolific Notikewin Member wells occur in a narrow east -west trend through Township 67 from ranges 8 to 13W6. In this trend Schmidt & Pemberton (2004) defined a barrier spit that was formed as sediments were introduced into a shoreline as a result of channel avulsion. This barrier had little progradational extent, instead growing longshore, creating a large estuarine/lagoonal complex.…”

Enormous volumes of gas (.30 Tcf ) are contained within the deepest portions of the Western Canada Foreland Basin, where tight gas-saturated Cretaceous sandstones grade updip into porous water-saturated sandstones. Production has occurred from coarse-grained shoreline sands both near the updip gas-water interface, such as those found in the Elmworth Field, and from low-porosity-permeability reservoirs found deeper in the basin. These basin-centred gas (BCG) reservoirs are characterized by regionally pervasive gas-saturated lithologies, abnormal pressures and no downdip water contact, and occur in low-permeability reservoirs. The keys to Shell's exploration success were an understanding of the stratigraphy, sedimentology and rock properties of the basin, the development of structural, petrophysical and geomechanical models, development of an understanding of the desiccation or dewatering process, the distribution of water within the basin and how the pressure regime evolved, interpretation of 3D seismic, and an aggressive land strategy. The evaluation of structural leads was aided when seismic and geomechanical modelling were combined, thereby aiding in the prediction of zones with a higher probability of encountering favourable reservoir producibility characteristics, that is, areas where a well developed, well connected open fracture network is expected. This multidisciplinary approach has resulted in economic success in regions once thought to be non-productive, and where it was once said, 'People go broke chasing the Nikanassin'.

“…Simultaneously, conglomerate reservoirs have become increasingly important and gaining more attention worldwide (Arnott, 2003;Hart and Plint, 2003;Hong et al, 2007;Liang et al, 2000;Rogers, 2007;Ş en et al, 2009;Wang et al, 2006;Zhu et al, 2003aZhu et al, , 2003bZonneveld and Moslow, 2004). For example, the lower Cretaceous Falher Member shoreface conglomerates, that are the most prolific natural gas reservoirs of the Alberta and British Columbia Deep Basin in Western Canada, have been studied for aspects of sequence stratigraphy, sedimentology, outcrop and palaeontology (Arnott, 2003;Clifton, 2003;Hart and Plint, 2003;Maceachern and Hobbs, 2004;Moslow and Zonneveld, 2004;Schmidt and Pemberton, 2004;Zonneveld and Moslow, 2004). The Garfield conglomerate pool in central Kansas (USA) was studied to develop a new reservoir model (Rogers, 2007).…”
