ItemA geological and stratigraphic study report of Kibuku area, Semliki Basin, Albertine Graben( 2018-05-28) Odong, AnthonyThe Semliki Basin is covered by sediments that represent the Middle Miocene to recent, which are described from outcrop and well data, underlain by possible Jurassic or Permo-Triassic to Early Tertiary sediments which rest unconformable on Basement, describes from seismic data. Sediments in Semliki Basin are predominantly composed of sandstones, siltstones and claystones while the basement rocks consist of high grade metamorphic and igneous rocks such as granite, granite gneiss, amphibolite and quartz veins and the study has allowed a better understanding of the stratigraphic relationship of the different rock units that are exposed on out crop, those encountered in the wells, a section interpreted from seismic data. The depositional environment of the sediments in the Semliki Basin is fluvial-lacustrine/deltaic showing significant variations in gamma ray character, which reflect the water-level changes and river interactions through the depositional period and the influence of rifting tectonics on sediment deposition through time and space. The surface manifestation of Sempaya Hotspring is evident for the early maturation of the organic matter to expel Oil in the young sediments of Albertine Graben. The sediments in the Semliki Basin represents petroleum play for hydrocarbon accumulations, in which the necessary elements of a valid petroleum systems were identified. These include excellent or good potential for reservoir and seal as well as circumstantial evidence of regionally mature source rocks, possible seals, traps and hydrocarbon-migration pathways.

ItemA report on a field study of Kibuku Area in the South and East of the L. Albert Basin in Ntoroko District, Western Uganda(Makerere University, 2019-06-20) Davis, TushabomweThis report entails information pertaining a field study that was carried from 10 th June 2018to 23rd June 2018 to the Albertine Graben area, South and East of the Lake Albert Basin. The respective target areas were Kichwamba and Kibuku in the Semliki basin. The topics of interest in this study were; the East African Rift System, drainage and drainage reversal, braided river systems, geophysical and etrophysical data interpretation, depositional environments, and facies analysis. The study involved a number of drives to the study area, group and individual exercises, lithologic logging as well as group presentations and discussions.
