Isotopic characteristics of carbon and oxygen within ordovician carbonate paleokarst in the tazhong region and their paleoenvironmental significance

Frontiers in Earth Science, 2023
The Tazhong region is a key area for oil and gas exploration and development within the Tarim basin. In this region, development of Ordovician carbonate paleokarsts has been found to be extremely heterogeneous.

Sedimentary environment and petrological features of organic-rich fine sediments in shallow water overlapping deposits: A case study of Cambrian Yuertus Formation in northwestern Tarim Basin, NW China

Petroleum Exploration and Development, 2020
: Taking the Cambrian Yuertus Formation outcrop profiles in the Aksu-Keping-Wushi areas of northwestern Tarim Basin as examples, the depositional environments of organic rich fine sediment were analyzed by examining the outcrop profiles macroscopically ...

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 ...

An Impressive Impact on Well Productivity by Hydrochloric Acidizing of Vuggy Carbonate Reservoir: A Case Study [PDF]

Iranian Journal of Oil & Gas Science and Technology, 2017
Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after ...

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 ...

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.

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 ...

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.
