Examples of Paleokarst in Mesozoic Carbonate Formations in the Carpathian Foreland Area

Energies
A paleokarst system developed in the Upper Jurassic–Lower Cretaceous carbonate complex has been recognized in the Carpathian Foreland area. Well logs testing and core data as well as an acoustic imager, a microresistivity scanner and six-arm dipmeter ...

Structure and Filling Characteristics of Paleokarst Reservoirs in the Northern Tarim Basin, Revealed by Outcrop, Core and Borehole Images

Open Geosciences, 2017
The Ordovician paleokarst reservoirs in the Tahe oilfield, with burial depths of over 5300 m, experienced multiple phases of geologic processes and exhibit strong heterogeneity. Core testing can be used to analyse the characteristics of typical points at

A framework for assessing the role of karst conduit morphology, hydrology, and evolution in the transport and storage of carbon and associated sediments

Acta Carsologica, 2013
Karst aquifers and conduits form by dissolution of carbonate minerals and the slow release of inorganic carbon to the surface environment. As conduits evolve in size, morphology, and position within the aquifer, their function and capacity change ...

Study on the development model of deep carbonate paleokarst reservoirs in the Tarim Basin

Carsologica Sinica
As a critical hydrocarbon-bearing basin in China, the Tarim Basin contains exceptionally abundant oil and gas resources within its Paleozoic marine carbonate formations, particularly in the deep subsurface where it exhibits significant exploration ...

Rock Magnetic‐Based Cyclic Expression in Late Visean Ramp Carbonates and an Astrochronology for the Late Asbian From Northwest England

Paleoceanography and Paleoclimatology, Volume 39, Issue 3, March 2024.
Abstract The late Asbian appears to mark the initial, well‐documented, onset of far‐field glacio‐eustatic changes in equatorial Mississippian strata. This work unravels the nature of cyclicity in upper Asbian shallow marine carbonates, using a combination of petrographic study, rock magnetic proxies and astrochronological testing on samples from the ...

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 ...
