Characteristics of Longwangmiao reservoirs in Penglai gas area and comparison with those in Moxi-Gaoshiti area, central Sichuan Basin

Shiyou shiyan dizhi
The Lower Cambrian Longwangmiao Formation in the Penglai gas area has promising carbonate reservoirs and exhibit strong gas indications, making itself a pivotal exploration zone following the Anyue gas field in the central Sichuan region.

Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Application of mapping and dating techniques in the study of ancient carbonate reservoirs: A case study of Sinian Qigebrak Formation in northwestern Tarim Basin, NW China

Petroleum Exploration and Development, 2020
Ancient marine carbonates experienced complex modifications, making it difficult to identify reservoir genesis and effective porosity before hydrocarbon migration.

Oxygen isotope thermometry and composition of aqueous fluids within the parent body of asteroid (101955) Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...

Episodic dolomitization of Paleozoic limestones in the Kinta Valley, Malaysia: Implications on porosity evolution and reservoir properties

Energy Geoscience, 2021
Carbonates undergo a variety of physical, mineralogical, chemical changes during depositional and post-depositional stages that are of interest to exploration geologists and sedimentologists.

Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

Meteoritics &Planetary Science, EarlyView.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

Applciation of UVA oblique photogrammetry in multi-scale characterization of Yunhuatan shoal reservoir in the Maokou Formation, central Sichuan Basin: A case study on the Hongyan outcrop section, Huaying

Carsologica Sinica
In recent years, guided by the concept of facies-controlled reservoirs, high-quality porous dolomite reservoirs of platform margin facies in Member 2 of the Maokou Formation (Mao-2 Member) have been discovered on the northern slope of Central Sichuan and

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Carbonate facies, diagenesis and sequence stratigraphy of an eocene nummulitic seservoir interval (jdeir formation), offshore NW Libya [PDF]

, 2006
This study investigates the sedimentology, petrology and depositional environments of a major Early Eocene nummulitic reservoir unit: the Jdeir Formation, from offshore NW Libya in the Mediterranean Sea. This formation is a prolific hydrocarbon-producing
