The Cretaceous pelagic carbonate succession, i.e., Goru Formation was studied in the Chutair Section, Sulaiman Range, representing part of eastern Tethys for paleoenvironment and bio-sequence stratigraphy. Eight planktonic foraminiferal biozones are identified which include: 1. Muricohedbergella planispira Interval Zone; 2. Ticinella primula 3. Biticinella breggiensis 4. Rotalipora appenninica ...

the asmari formation is a thick carbonate sequence in zagros foreland basin. it was deposited during oligocene – early miocene ages. in order to interpret the depositional environment and sequence stratigraphy, firuzabad section were compared with 4 sections of asmari formation in the zagros basin. four different sub environments were identified in the asmari formation based on microfacies anal...

The distribution characteristics of single sand body are mainly used to identify the underground with geological techniques. With help core data and well logging data, sedimentary microfacies studied in detail, so as study plane vertical. This paper studies tight reservoir a area actively discusses its development potential, aiming at obtaining more scientific reasonable research results, provi...

The objective area is a complex fault-block reservoir, and is provided by China Petroleum Engineering Design Competition(CPEDC). Reservoir characteristics, including stratigraphic features, vertical changes and section properties (thickness, percentage sand and percentage amalgamation) are documented. Based on comprehensive analysis on structural architecture and reservoir characteristics, a th...

The Neogene Guantao Formation Reservoir in the PLOilfield is a unconsolidated sandstone with high porosity and permeability. reservoir diagenesis weak dominated by compaction diagenesis. At present, insufficient research into relationship between pore characteristics sedimentary microfacies of shallow delta reservoirs restricts prediction favorable distribution. This article takes as object ana...

Coralline red algae are highly abunadant and well diversified in the well exposed carbonate deposits of the Lower Pliocene Shagra Formation at Wadi Wizer, Red Sea coast, Egypt. Lithostratigraphically, the Shagra Formation unconformably overlies the Late Miocene Marsa Alam Formation and underlies the Quaternary deposits. This carbonate facies is dominated by different assemblage of coralline red...

The sediments of the Hartha Formation were deposited during Upper Campanian- Maastrichtian cycle. Due to importance this sequence in terms stratification and economics oil industry, it has been focused on study. present study includes three fields central Iraq within Mesopotaminan Zone, East Baghdad, Balad Kifl fields. This was accomplished by describing 190 thin sections interpreting response ...
