Hydrocarbon Geochemical Characteristics and Depositional Environment of Tertiary Tar Sand from Ondo, SW Nigeria.

Evaluation of background geochemical speciation of heavy metals in overburden topsoil of bituminous sand deposit area, Ondo state, Nigeria

Metals are ubiquitous within the earth crust. However, the exceptional high-level concentration of heavy metals in the soil due to natural or anthropogenic activities and the chemical forms in which they exist determine the level of risk they portend to the environment. This work was aimed at determining the background level of the presence of seven priority toxic metals (Cr, Ni, Pb, As, Cd, Cu...

Relationship Between Depositional Facies and Reservoir Characteristics of the Oligo-Miocene Asmari Formation, Aghajari Oilfield, SW Iran

The present study focuses on facies analysis and the reservoir characteristics of the Asmari Formation in the Aghajari oilfield (located in the Zagros fold-thrust belt, southwest Iran), and how they are linked to depositional environments and reservoir characteristics. This formation consists of about 380 m carbonates with some siliciclastic intercalations. Based on the integration of 1200 m of...

Depositional History of Miocene-Age Sediments from the Weddell Sea, Antarctica, Using Sedimentological and Geochemical Proxies

Understanding the stability of Antarctic Ice Sheets is a key to understanding past climates and the response of ice-sheets to warming. In this thesis, I examined the middle through upper Miocene marine sedimentological and geochemical record in the Weddell Sea. Sediments were recovered at Ocean Drilling Program (ODP) Site 694 located in 4653 m of water in the northern Weddell Sea Abyssal Plain,...

Geochemical Characteristics and Hydrocarbon Generation Modelling of Early Triassic to Late Cretaceous Formations within Ogaden Basin, Ethiopia

The major goal of this study is the evaluation of the source rock of Ogaden Basin using Rock-Eval Pyrolysis, Vitrinite reflectance (%Ro), and well log data of the Permo-Triassic and the Mesozoic sequences including Karro, Hamanlei, and Urandab Formations. Burial history and level of thermal maturity of the Bodle-1 well, the Calub-1 well and the Hilala-2 well were modeled based on the calibratio...
