ESTIMATION OF CARBON SINK IN SURFACE CARBONATE ROCKS OF GUANGXI PROVINCE BY USING REMOTE SENSING IMAGES
Dissolution test method Carbonate rocks Miss carbon sink ArcGIS
2018/5/14
Studies of the imbalance of source sinks in the carbon cycle show that CO2 absorbed during rock weathering is part of the "miss carbon" of the global carbon cycle. The carbon sink contribution of carb...
Oil charging history and pathways of the Ordovician carbonate reservoir in the Tuoputai region, Tarim Basin, NW China
Oil population Oil charging events Fluid inclusion 1D numerical modeling Oil filling pathway
2018/4/2
Geochemical analysis of 64 oils sampled from an Ordovician carbonate reservoir in the Tuoputai region was undertaken to study the composition of molecular markers. All the oils have similar geochemica...
Review of surfactant-assisted chemical enhanced oil recovery for carbonate reservoirs: challenges and future perspectives
Oil reserves Original oil in place Carbonate formations Surfactants Chemical enhanced oil recovery
2018/4/2
A significant fraction of the conventional oil reserves globally is in carbonate formations which contain a substantial amount of residual oil. Since primary and secondary recovery methods fail to yie...
Impact of animal manure addition on the weathering of agricultural lime in acidic soils: The agent of carbonate weathering
Carbonate weathering Soil/atmospheric CO2 CO2 source/sink
2018/3/23
Fertilization and aglime (agricultural lime) application, as important agricultural activities in acid soil, exert an influence on the fluxes of carbon both between and within ecosystems. Animal manur...
EAGE Workshop on Petroleum Geochemistry in Operations & Production A Tale of Fluids in Carbonate Res

2016/7/26
This workshop targets operational petroleum geochemistry in carbonate reservoirs. The goal is to provide a perspective on how established and emerging geochemical tools can help to have a comprehensiv...
Micron-scale d13C determination by NanoSIMS in a Juina diamond with a carbonate inclusion
sub-lithospheric diamonds Juina carbonate lower mantle peridotite eclogite
2017/4/10
Juina diamonds present a wide spectrum of mineral inclusions, covering both peridotitic and eclogitic composition.
Among the most rare inclusions, carbonates are interpreted as an evidence of deep re...
Growth and subsidence of carbonate platforms: numerical modelling and application to the Dolomites, Italy
lithospheric flexure differential compaction Triassic
2015/9/15
The phenomenon of subsidence induced by the growth of carbonate platforms has been investigated with the aid of numerical modelling. The research aimed to quantify the relative contribution of this pr...
