Introduction: Deciphering the stratigraphy of the Martian North Polar Layered Deposits (NPLD) may provide critical insight into climatic processes on Mars. Detailed layering is exposed within NPLD troughs, the stratigraphy of which can either simply appear straightlying or manifest in a more complex offset pattern (Fig. 1). Here we examine small-scale variations in the stratigraphy of offset tr...

the aitamir formation (albian- cenomanian) in the kopet- dagh basin consists of fine to medium grained sandstone, siltstone, shale and limestone. its lower contact with the sanganeh formation is gradual and its upper contact with the abderaz formation is unconformable. field and petrographic studies of the aitamir formation in artenj and ghorghoreh sections, located in bazangan area- east of ko...

The Oligo-miocene Asmari formation is one of the most important hydrocarbon reservoirs in the southwest of Iran. In order to evaluate reservoir quality and the factors controlling reservoir properties, detailed geological and petrophysical studies were carried out on 242 m of core samples from Asmari reservoir. This study is a part of a larger project that examines depositional history and rese...

The Anthropocene, an informal term used to signal the impact of collective human activity on biological, physical and chemical processes on the Earth system, is assessed using stratigraphic criteria. It is complex in time, space and process, and may be considered in terms of the scale, relative timing, duration and novelty of its various phenomena. The lithostratigraphic signal includes both di...

Beginning with this issue, the Journal of Paleontology will be publishing an occasional section entitled ‘‘View from the Field’’. ‘‘View from the Field’’ will provide a forum for concise commentary on current issues in paleontology, including but not limited to discussion of methods, important new discoveries, and major conceptual advances. Contributions should be brief (no more than 12 double-...

Stratigraphy is the science that studies the strata, or beds, of (mainly) sedimentary rocks in order to extract from them the history of the earth’s surface. By grouping the bed successions in stratigraphic units and by studying their geometrical relationships with some simple rules, it creates the fundamental temporal relative framework necessary to understand the origin of the rock units them...

RESULTS Drilled four wells based on the model, successfully predicting the type and thickness of reservoir facies, enabling the operator to pursue optimal field development strategies with higher confidence in the distribution and connectivity of critical flow units. Modeling reservoir architecture with limited data After successfully developing Cretaceous reservoirs in several northern Kuwait ...

For a more accurate reservoir prediction of braided delta front, the method High Resolution Sequence Stratigraphy was adopted in Moxizhuang Oil Field with assistance Comprehensive Prediction Error Filter Analysis. J 1s2 divided into 2 fifth-order base-level cycles, 5 sixth-order turnaround surfaces rise to fall, and time-equal correlation shallow front achieved. Through study microfacies frame,...
