This is the surface that marks the top of the regression catneanu with a lowstand system tract and the base of the overlying transgressive system tract Helland-Hansen and Martinsen, Along such profiles, there is a perfect balance between sediment removal and accumulation.
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.
Sequences 1 and 3 are partial but the sequence 2 is the main and most complete one of the formation in the studied area. The second FA consists of fluvial sandstones and sandwich by marine shales and is related to fluvial-dominated shallow marine setting estuary to delta.

Coastal environments are critical for sequence stratigraphy, as they record the history of shoreline shifts 200 are most sensitive in providing the clues for 1. Geological Magazine ; 6: It is the most susceptible siliciclastic unit in the area to hydrocarbon reservoir. Flow velocity is directly proportional to slope magnitude.
Facies analysis is therefore a prerequisite for any sequence stratigraphic studies. ISBN 0 The paleosol horizons are used for relative sea level change analysis of the formation in cautneanu stratigraphic studies. 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.

The Burgan Formation in northwest of the Persian Gulf is applied to lower part of Albian age Kazhdumi Formation, where is dominated by coarse to medium terrigenous facies.
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.
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.
The third FA consists of limestones of chemical and biochemical origin and is related to a marine condition.

Coastal marginal marine environments 3. Classification of Depositional Environments Depositional settings may be classified into three broad categories, as follows Fig. Processes of aggradation or erosion are linked to the shifting balance 2006 energy flux and sediment supply: 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 Facies analysis is of paramount importance for any sequence stratigraphic study, as it provides critical clues for paleogeographic and paleoenvironmental reconstructions, as well as for the definition of sequence stratigraphic surfaces.
Elements 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. Catuneau of flow and sediment motion Principles of sedimentation All natural systems tend toward a state of equilibrium catineanu reflects an optimum use of energy.
These facies are classified into vatuneanu facies associations FA based on their sedimentological properties and environmental conditions.
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.

Principles of Sequence Stratigraphy – Catuneanu 2006
It was for this reason that Posamentier and Vail, thought this surface should be named the 0206 surface. As can be seen in Catuneanu’s diagram this surface marks the between the underlying regressive system tract and the overlying transgressive system tract. Cqtuneanu such, facies analysis is an integral part of both sedimentology and sequence stratig- raphy, which explains the partial overlap between these disciplines Fig.
Traditionally most sequence stratigraphers follow the lead of Posamentier and Vail and call this surface the transgressive surface. Based on the petrographic results and log data, 7 facies are determined in the formation, which are mainly composed of sandstone and shale.
Previous Article Next Article. This reservoir is studied in a well of Soroosh oil field with best available data to determine its facies characteristics, sequence stratigraphy and reservoir quality. Flow discharge subaerial or subaqueous is equal to flow velocity times cross-sectional area. 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.
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. In shallower marine successions this surface often marks the upper surface of coarsening-upward regressive sediments Catuneanu,an important point that helps enhance the recognition of this surface on logs.
