Detection Of Hydrocarbon Seeps Using Remote Sensing Technique In The Rufiji Onshore Basin

ABSTRACT Hydrocarbon seeps cause chemical and mineralogical alterations at the surface, which can be identified geologically but also detected by remote sensing techniques. This work aimed at detecting mineral alteration induced by hydrocarbon seeps in a sandstone formation in Rufiji basin (Wingayongo), South Coast Tanzania. For this study, rock samples collected during fieldwork were petrographically analysed and the multispectral ASTER data was downloaded and utilized to characterize ...

Sedimentologic And Paleocurrent Analysis Of The Early Triassic Strata In The Ruhuhu Basin, Tanzania

ABSTRACTRuhuhu basin has eight informal lithostratigraphic units, termed the K1 to K8.This research was conducted at Lifua Member (formally K8). The beds are of Early Triassic and are the youngest stratigraphic unit of the Karoo strata in the RuhuhuBasin. This research applies sedimentology and paleocurrent analysisof the early Triassic strata in interpreting provenance, shape and orientation andreconstructing paleogeography of this unit.It involved description, measurements and sampling of t...

Characterization Of The Accommodation Zones Along Restraining And Releasing Bends From Analogue Modeling Simulating The Seagap Fault, Off-Shore Tanzania

ABSTRACTThere is poor understanding of geometry and evolution of the accommodation zonesalong the restraining and releasing bends in strike slip systems. This dissertationfocused on characterize the accommodation zones between restraining and releasingbends, with special focus on the influences of syn-kinematic sedimentation and thebasement pre-existing structuration by simulating the Seagap fault , Off-shoreTanzania.A set of three scaled sand models were performed, using a asement o set. m m...

Comparative Evaluation Of Sandstones Properties In Parts Of The Anambra Basin, Southeastern Nigeria

ABSTRACT The evaluation of sandstone properties in parts of the Anambra Basin was undertaken to identify the spatial distribution of textural, petrophysical and mineralogical properties of sandstone bodies in the area in order to assess their potentials to host hydrocarbons. Sandstone units from Nkporo Formation, Mamu Formation, Ajali Sandstone and Umuna Sandstone were subjected to textural analysis using sediment granulometry, thin-section petrography and geochemical analysis. Following...

Characterization And Depositional Environments Of Upper Cretaceous Sediments Exposed At Ikpankwu Quarry And Km 75, Port Hacourt- Enugu Road, Okigwe

ABSTRACT The study is on the characterization and depositional environment of upper Cretaceous sediments exposed at the Ihube-Ikpankwu Axis, Okigwe. The results of field and laboratory studies on selected samples of the study area show that the sediments in the study area are fine to medium grained, with an average mean size of 1.808Φ. The standard deviation (dispersion sorting) values range from 1.38 – 2.48 i.e. poorly to moderately sorted with an average value of 1.805Φ. The studie...
