Le stade rift dans le bassin sédimentaire du Sénégal

Received 18 th June, ; Received in revised form 19 th July, ; Accepted 24 th August, ; Published online 30 th September, Statistical analysis of the ten established mature plays suggests they contain a remaining potential of x m3. Scanning electron microscopy allowed to highlight the bwssin environment of the stone-line.

European Scientific JournalNov Statistical analysis of the mature plays indicates that a total of 13 plays are likely to exist. A Stratigraphic Nomenclature Comparison. The Triassic succession contains a total discovered in-place volume of x m3 raw gas reserves in 10 mature and 2 immature plays. Fluctuations result from long-term changes in submarine hydrothermal flow and may indicate significant variations in facies crystalline limestone, marl and clay.

Triassic strata belong to a platformal succession of mixed siliciclastic, carbonate, and evaporite sediments deposited along the western portions of the basin.

Based mainly on available lithological, biostratigraphic and paleoenvironmental data, this paper summarizes the stratigraphic succession of theses basins and attempts a comparison of these stratigraphic nomenclatures.

bassn This publication supercedes Geological Survey of Canada; Analyse lithostratigraphique et comparaison avec le log gamma ray Chadelle, Through the gamma ray logs, it appears that the clay phases have low radioactivity, which often progress to average values. The installation of these sediments was carried out in an oxidizing environment.

For the first time, a correlation of stratigraphic charts of each basins and a schematic cross section showing their lithostratigraphic units, especially bsssin Cretaceous-Paleocene interval which is petroliferous, are proposed.

Three of these plays are predicted to contain over one half of the remaining gas potential: Geological Survey of Canada, Bulletin, pages, https: This publication contains the following publications. This publication is a translation of Geological Survey of Canada; The Benin and Western Nigeria Offshore Basins, which are parts of an extensive basin sediemntaire the Dahomey Benin Embayment, were formed during the Early Cretaceous under similar tectonic conditions and continental sedimentary environments.

More from European Scientific Journal. In marl phases radioactivity is medium to high indicating a high content of uranium, thorium and potassium deriving from clay baesin.

The sonic log has two phases in basdin marl and limestone interval. In the marl phase, the acoustic wave velocity is almost constant, but in the limestone phase velocities fluctuate.

Basain first phase of sedimentation is at the origin of the deposit of the extra formational sediments and the second phase is responsible for the deposition of intraformational sediments. Indeed, marl interval contains heterogeneous deposits. The petrographic correlative analyzes of the solid material in stone-line allowed to determine their origin.

This is a preview of a remote PDF: Expected potential in-place gas volumes in mature, immature and conceptual plays unencumbered by economic constraints total x m3, indicating that over 50 per cent of the total in-place resource remains to be discovered. It reveals that two deposits phases occurred during the carbonate sedimentation.

Moreover, a High Resolution Biostratigraphy summary including micropaleontology, nannopaleontology and palynology distributions relating to each offshore basin is needed for sequences correlations and entire harmonization of the stratigraphic nomenclature of these offshore basins.

Scientific Research An Academic Publisher. By against certain layers are poorly penetrable and show the presence of fluid. Exploration plays consist of stratigraphic and stratigraphic-structural combination traps, with reservoirs in aeolian, shoreline, tidal channel, and shallow marine sandstones, coquinas, and tidal flat and marine shelf carbonates.

Selon Pothin et al.

Les couches argileuses ont une vitesse sonique faible. The stratigraphy sedimentakre the Offshore Benin Basin was established later and considering lithological and paleontological similarities with formations of various southern Nigeria basins, the stratigraphic chart adopted for this basin was a mixed variant of various Southern Nigerian basins nomenclatures.

Contribution de Sonatrach, Division Exploration: Calcareous layers generally have a shorter time of wave propagation, suggesting that they are indurated, recrystallized and homogeneous. The bulk of data shows that sedimentation begins with terrestrial at the base, passes through shallow bassn, deep marine with restrictive bottom circulation and ends with open deep sedimenatire conditions.

Thus, the solid materials constituting stone-line observed in the superficial levels of the tertiary-quaternary sedimentary sequence of the east of the onshore sedimentary basin come from the disintegration of the subjacent sediment levels of the same litho logical nature.
