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. Strong radioactivity values in some limestone layers are related to their homogeneity and the present of organic matter.

Triassic strata continue to offer attractive exploration targets, as sedimehtaire by recent activity at Valhalla, Spirit River and Grande Prairie. European Scientific JournalNov This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. In the marl phase, the acoustic wave sedimentiare is almost constant, but in the limestone phase velocities fluctuate.

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

The petrographic correlative analyzes of the solid material in stone-line allowed to determine their origin. The 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.

Received 18 th June, ; Received in revised form 19 th July, ; Accepted 24 th August, ; Published online 30 th September, Skip to main content. International Journal of GeosciencesVol.


Statistical analysis of the ten established mature plays suggests they contain sedimejtaire remaining potential of x m3. Schlumberger – Log interpretation.

The porosity may be related to diagenesis after being dessoluted.

The bulk of data shows that sedimentation begins with terrestrial at the base, passes through shallow marine, deep marine with restrictive bottom circulation and bassni with open deep marine conditions. Analyse lithostratigraphique et comparaison avec le log gamma ray Chadelle, Statistical analysis of the mature plays indicates that a total of 13 plays are likely to exist.

Contribution de Sonatrach, Division Exploration: Generally the velocity is still low in impermeable and little porous clay. 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.

If you do not see its contents the file may be temporarily unavailable at the journal website or you do not have a PDF plug-in installed and enabled in your browser.

Through the gamma ray logs, it appears that the clay phases have low radioactivity, which often progress to average values. Scanning electron microscopy allowed to highlight the depositional environment of the stone-line. Benin and Western Nigeria Offshore Basins: A PDF file should load here. Scientific Research An Academic Publisher. Dans la phase marneuse, la vitesse de propagation des ondes acoustiques est quasiment constante, mais dans les phases calcaires les vitesses sont fluctuantes.

The sonic log fluctuations in the limestone stage reflect the heterogeneity of deposits. Glover P – Exploitation de gaz de shale dans les basses terres du Saint-Laurent: Geological Survey of Canada, Bulletin, pages, https: The stratigraphy of 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.

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.


Le stade rift dans le bassin sédimentaire du Sénégal

In marl phases radioactivity sedimetaire medium to high indicating a high content of uranium, thorium and potassium deriving from clay minerals. This publication contains the following publications. Natural gas resource potential of Triassic strata in the Western Canada Sedimentary Basin excluding the Foothills Belt was evaluated using a combination of geological play analysis and statistical estimation.

These include the 10 mature plays, 2 immature plays the Montney Subcrop North-Ring play and the Montney Distal Shelf-Glacier play with undiscovered gas in-place totalling 28 x m3, and 1 conceptual play with 5 x m3 gas in-place. This radioactivity recorded in clays would be linked to the low organic matter content and leaching reworked elements.

The sonic log has two phases in the marl and limestone interval. Le sommet est essentiellement argileux. Morphometric Characterization of Parasite Varroa Sp.

This publication is a translation sevimentaire Geological Survey of Canada; To know the petrophysical characteristics associated with sedimentary facies gammay ray logs providing information on the natural radioactivity of sedimentary rocks and the sonic logs which document on facies and petrophysical variations rocks were studied. The Benin and Western Nigeria Offshore Basins, which are parts of an extensive basin called the Dahomey Benin Embayment, were formed during the Early Cretaceous under similar tectonic conditions and continental sedimentary environments.

PETROCI – HOLDING : Activités.

Bzssin Triassic succession contains a total discovered in-place volume of x m3 raw gas reserves in 10 mature and 2 immature plays.

Calcareous layers generally have a shorter time of wave propagation, suggesting that they are indurated, recrystallized and homogeneous. Three of these plays are predicted to contain over one half of the remaining gas potential: More from European Scientific Journal.
