Types of Fluid Alteration and Developing Mechanism of Deep Marine Carbonate Reservoirs

Geofluids, Volume 2019, Issue 1, 2019., 2019
Accurate recognition of the types of alteration fluid and the development mechanisms are important concerns in studying deep marine carbonate reservoirs. Major fluid types, such as seawater, meteoric water, deep burial formation water, hydrothermal fluid, and thermochemical sulfate reduction‐ (TSR‐) derived fluid, were identified based on carbon ...

Replication data for: Paleokarst reservoir modelling - A concept-driven approach

, 2021
Paleokarst reservoir model of the Agios Georgios cave system in northern Greece. A cave survey of the cave system is used to simulate collapse and infill processes and to generate paleokarst reservoir analogues.

Geological Composition and Structure of the Filling Zone and Its Water‐Resisting Property Evaluation on the Top of Ordovician Limestone

Geofluids, Volume 2019, Issue 1, 2019., 2019
With the gradual increase in mining depth of coal fields in North China, the threat posed by karstic Ordovician limestone water to the safe stoping of mines is becoming increasingly prominent. Investigating the water‐resisting property of the filling zone on the top of the Ordovician limestone provides the key to safe mining under pressure.

Multiphase Calcite Cementation and Fluids Evolution of a Deeply Buried Carbonate Reservoir in the Upper Ordovician Lianglitag Formation, Tahe Oilfield, Tarim Basin, NW China

Geofluids, Volume 2017, Issue 1, 2017., 2017
Oil and gas have been found in the Upper Ordovician Lianglitag Formation carbonates in the Tahe Oilfield, Tarim Basin, NW China. This study documents the origin of diagenetic fluids by using a combination of petrology, SIMS, fluid inclusion, and radiogenic isotope analysis. Six stages of calcite cements were revealed.

Geocellular rendering of cave surveys in paleokarst reservoir models [PDF]

, 2020
Infilled and collapsed cave systems are an important component of many paleokarst reservoirs. Incorporating these features into industrial reservoir models commonly relies on geostatistical modelling methods that often fail to capture key aspects of ...

Distribution of Upper Paleozoic Coal Seams in the Southeastern Ordos Basin

Energies, 2022
The Ordos Basin contains abundant coal resources in the Upper Paleozoic strata. They are shallowly buried or exposed in the periphery of the basin, forming recoverable coal mines and coalbed methane resources.

Seismic Characterization of Hypogenic Karst Systems Associated with Deep Hydrothermal Fluids in the Middle‐Lower Ordovician Yingshan Formation of the Shunnan Area, Tarim Basin, NW China

Geofluids, Volume 2017, Issue 1, 2017., 2017
Two fundamental forms of hypogenic karst systems (lateral stratiform hypogenic and cross‐formational fault‐vein hypogenic karst system) are distinguished mainly by differential effects of preexisting faults. In seismic cross sections, hypogenic karst systems are expressed as complex string-beads‐like seismic reflections associated with faults.

Les grottes du massif des Calanques (Marseilleveyre - Puget - Riou, France) : géologie, géomorphologie, sédimentologie

Physio-Géo, 2012
Description and speleogenesis of some caves in the calcareous formations of the "Massif des Calanques" in relation with lithology and tectonic environments: faults, Sormiou anticline, submersion coast in the "Calanques" valleys, karstic landscapes until ...

Ancient karst at the eastern slope of the Middle Urals and the Early-Middle Carboniferous boundary

Литосфера, 2016
The paleokarst occurrences associated with Lower Carboniferous limestones in the east of the Middle Urals are considered. We analyse the nature of the Early-Middle Carboniferous boundary.

Differences of carbon and oxygen isotopes in coarse-grained calcite from the Permian Maokou Formation in different regions of Sichuan Basin and their significance in paleokarst environment

Carsologica Sinica
Oil and gas fields in karst carbonate reservoirs are widely distributed in China. A number of karst fracture-vuggy reservoirs have been found in the Tarim Basin, the Ordos Basin and the Sichuan Basin.
