Systematic laboratory approach to produce Mg-rich carbonates at low temperature
(
Royal Society of Chemistry
, 2021 , Article)
Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate minerals necessary to form ...
Variability of blue carbon storage in arid evaporitic environment of two coastal Sabkhas or mudflats
(
Nature Research
, 2023 , Article)
Coastal Sabkhas are mudflats found in arid coastal regions that are located within the supratidal zone when high rates of evaporation lead to high salinity. While evaporitic minerals often accumulate underneath the surface, ...
Oil-polluted groundwater in central and west Iraq as indicator of potential new hydrocarbon plays
(
Taylor and Francis Ltd.
, 2023 , Article)
The old land of Iraq is characterized by the presence of many oil seepages that date back to the Babylonian time. During the last few years, the country has witnessed an accelerating pattern of earthquakes that may have ...
Geochemical characterization and origin of the Cretaceous Sa’di, Khasib, Mishrif, and Nahr Umr Crude Oils in Halfaya Oilfield, Southern Mesopotamian Basin, Iraq
(
Taylor and Francis Ltd.
, 2021 , Article)
A suite of crude oil samples from the Cretaceous reservoirs in Halfaya Oilfield, Southern Iraq were analyzed using organic geochemistry analysis to study their geochemical characterization and origin. High sulfur content ...
Microbially influenced formation of anhydrite at low temperature
(
Elsevier B.V.
, 2023 , Article)
Calcium sulfate minerals are abundant in nature – on Earth and on Mars – and important in several fields of material sciences. With respect to gypsum and bassanite, anhydrite represents the anhydrous crystalline phase in ...
Seismic detection and characterization of a man-made karst analog - A feasibility study
(
Society of Exploration Geophysicists
, 2021 , Article)
At the site of a water drainage shaft on the campus of Qatar University that serves as a man-made karst analog, two seismic imaging techniques were adapted to use resonant scattered waves recorded during active-source ...
The importance of microbial mats for dolomite formation in the Dohat Faishakh sabkha, Qatar
(
Springer Verlag
, 2015 , Article)
The Dohat Faishakh sabkha in Qatar is one of the rare modern environments where it is possible to study the formation of dolomite, a mineral whose origin has been long debated. In previous studies, dolomite formation in ...
Raman spectroscopy of the Dukhan sabkha: identification of geological and biogeological molecules in an extreme environment
(
The Royal Society
, 2010 , Article)
The characterization of minerals and biogeological deposits in a terrestrial Arabian sabkha has a direct relevance for the exploration of Mars since the discovery by the NASA rovers Spirit and Opportunity of evaporate ...
Raman Spectroscopic and Microbial Study of Biofilms Hosted Gypsum Deposits in the Hypersaline Wetlands: Astrobiological Perspective
(
Mary Ann Liebert Inc.
, 2023 , Article)
Gypsum (CaSO4.2H2O) has been identified at the surface of Mars, by both orbiters and rovers. Because gypsum mostly forms in the presence of liquid water as an essential element for sustaining microbial life and has a low ...
Novel methodology to couple decline curve analysis with CFD reservoir simulations for complex shale gas reservoirs
(
John Wiley and Sons Inc
, 2024 , Article)
Shale reservoirs are highly complex and are difficult to study using conventional reservoir simulation tools. This study introduces a novel methodology for estimating production from complex shale gas reservoirs by coupling ...
