Chemical Compositions in Modified Salinity Waterflooding of Carbonate Reservoirs -- Experiment [PDF]

open access: yes, 2021
Modified or low-salinity waterflooding of carbonate oil reservoirs is of considerable economic interest because of potentially inexpensive incremental oilproduction.

The formation of the ocean’s anthropogenic carbon reservoir [PDF]

open access: yesScientific Reports, 2016
AbstractThe shallow overturning circulation of the oceans transports heat from the tropics to the mid-latitudes. This overturning also influences the uptake and storage of anthropogenic carbon (Cant). We demonstrate this by quantifying the relative importance of ocean thermodynamics, circulation and biogeochemistry in a global biochemistry and ...

Control of paleogeographic pattern on sedimentary differentiation of evaporite-carbonate symbiotic system: A case study of the sixth sub-member of Ordovician Majiagou Formation M5 Member in central-eastern Ordos Basin, NW China

open access: yesPetroleum Exploration and Development, 2022
The relationship between paleogeographic pattern and sedimentary differentiation of evaporite-carbonate symbiotic system is examined based on logging, core and thin section data, by taking the sixth sub-member of fifth member of Ordovician Majiagou ...

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

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

Lithostratigraphy and depositional episodes of the Oligocene carbonate-rich Tikorangi Formation, Taranaki Basin, New Zealand [PDF]

open access: yes, 2003
The subsurface Oligocene Tikorangi Formation is a unique and important oil producer in the onshore Waihapa-Ngaere Field, Taranaki Basin, being the only carbonate and fracture-producing reservoir within the basin. Core sample data from seven onshore wells

Chemical Compositions in Salinity Waterflooding of Carbonate Reservoirs: Theory [PDF]

open access: yes, 2020
Higher oil recovery after waterflood in carbonate reservoirs is attributed to increasing water wettability of the rock that in turn relies on complicated surface chemistry.

Reservoir characteristics and genesis of the Ordovician M54−1a in the central and eastern parts of the Ordos Basin, China

open access: yesJournal of Natural Gas Geoscience, 2020
M54−1a is a new natural gas exploration target of the Ordovician in the Ordos Basin and is expected to have large-scale reserves and a production increasing area after M51 and M52 weathering crust gas reservoir.

Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: A synthesis and review [PDF]

open access: yes, 1996
The stable oxygen isotope composition (δ18O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (δ13C) reflects the source of CO2 for ...

The adsorption and inhibition mechanism of 1-Phenyltetrazole-5-thiol for X70 steel corrosion in H2SO4 medium

open access: yesInternational Journal of Electrochemical Science, 2021
This work aimed to develop a high-efficiency and reliable alternative for conventional and toxic corrosion inhibitor. A novel tetrazole derivative (1-Phenyltetrazole-5-thiol, PTT) that possessed excellent anti-corrosion capacity was exploited for the ...
