According to their reservoir quality, these facies associations show a decreasing trend in porosity and permeability values from FA1 to FA3. You do not currently have access to this article. Review Article November 01, Journal of Sedimentary Research 66 4— Previous Article Next Article. Flow discharge subaerial or subaqueous is equal to flow velocity times cross-sectional area. On the diagram Catuneanu shows the maximum regressive surface as conformable. The direction of lateral facies shifts progradation, retrogradation reflects the balance between sedimentation rates and the rates of change in the space available for sediment to accumulate.
It is the most susceptible siliciclastic unit in the area to hydrocarbon reservoir. Traditionally most sequence stratigraphers follow the lead of Posamentier and Vail and call this surface the transgressive surface. Facies analysis is of paramount importance for any sequence stratigraphic study, as it provides critical clues for paleogeographic and paleoenvironmental reconstructions, 0206 well as for the definition of sequence stratigraphic surfaces.
International Association of Sedimentologists Special Publication, pp.
The understand- ing of facies and their associations are also essential for the correct interpretation of sequence stratigraphic surfaces, as is explained in more detail in Chapter 4.
Catuneanuu of what we now understand as sequence stratigraphy had been rumbling along in the background for some time before the explosion that started to appear in the scientific literature in the late s.

However in shallower settings the transgression that accompanies a base level rise may erode the upper surface of the underlying regressive sequence Loutit et al. Facies analysis is therefore a prerequisite for any sequence stratigraphic studies.
Principles of Sequence Stratigraphy.: The second FA consists of fluvial sandstones and sandwich by marine shales and is related to fluvial-dominated shallow marine catuneany estuary to delta. You could not be signed in.
As can be seen in Catuneanu’s diagram this surface marks the between the underlying regressive system tract and the overlying transgressive system tract. Based on the results from this study, three 3rd order sequences have been identified.
Trevor Elliott; C atuneanuO. The paleosol horizons are used for relative sea level change analysis of the formation in sequence stratigraphic studies.
It is easy, with the benefit of hindsight, to find key elements of the concepts in papers published during the s and s but we had to wait until the s for these Following the introduction to the various methods, a general guideline for a step-by- step sequence stratigraphic workflow is provided as a practical approach to the generation of geological models. The Burgan Formation catumeanu northwest of the Persian Gulf is applied to lower part of Albian age Kazhdumi Formation, where is dominated by coarse to medium terrigenous facies.

Scientific Research An Academic Publisher. Fluid and sediment gravity flows tend to move from high to low elevations, following pathways catuneeanu require the least amount of energy for fluid and sediment motion.
Within the nonmarine portion of the basin, a distinction can be made between the steeper-gradient alluvial plain, which captures the upstream reaches of fluvial systems, and the gently sloping coastal plain that may develop within the downstream reaches of the fluvial environment Fig. ISBN 0 2. Based on the petrographic results and log data, 7 facies are determined in the formation, which are mainly composed of sandstone and shale.
Coastal environments are critical for sequence stratigraphy, as they record the history of shoreline shifts and are most sensitive in providing the clues for 1. The study of depositional systems is cayuneanu related to the concepts of facies, facies associations, and facies models, which are defined in Fig. In the context of sequence stratigraphy, facies analysis is particularly relevant to the study of cyclic changes in the processes that form individual depositional systems in response to base- level shifts.
Processes of aggradation or erosion are linked to the shifting balance between energy flux and sediment supply: Librarian Administrator Sign In. As such, facies analysis is an integral part of both sedimentology and sequence stratig- raphy, which explains the partial overlap between ctuneanu disciplines Fig.

Trevor Elliott Trevor Elliott. VolumeNumber 6. Principles of flow and sediment motion Principles of sedimentation All natural systems tend toward a state of equilibrium that reflects an optimum use of energy. Email alerts New issue alert. Each of these methods forms the core of a more conventional and dedicated discipline, so this presentation only reiterates aspects that are particularly relevant to sequence stratigraphy. It was for this reason that Posamentier and Vail, thought this surface should be named the transgressive surface.
FA2, presenting a medium reservoir quality, is more frequent in the middle parts of studied formation and FA3 is found almost in the upper parts. Citing articles via Google Scholar. ISBN 0 Others like Nummedal et al. Deltas – transgressive river mouths: This chapter presents a brief account of the main methods that need to be integrated into a comprehen- sive sequence stratigraphic analysis, including facies analysis of ancient deposits outcrops, core and modern environments; analysis of well-log signatures; analysis of seismic data; and the achievement of time control via relative and absolute age determinations.
Sediment load volume is directly proportional to the transport capacity of the flow, which reflects the combination of flow discharge and velocity.
The coastal prism is wedge shaped, and expands landward from the coastal environment by onlapping the pre-existing topography in an upstream direction.
