Dans la phase marneuse, la vitesse de propagation des ondes acoustiques est quasiment constante, mais dans les phases calcaires les vitesses sont fluctuantes.

Alternatively, you can download the file locally and open with any standalone PDF reader: Le sommet est essentiellement argileux. Morphometric Characterization of Parasite Varroa Sp. 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.
Skip to main content. Scanning electron microscopy allowed to highlight the depositional environment of the stone-line. This publication supercedes Geological Survey of Canada; Schlumberger – Log interpretation.
PETROCI – HOLDING : Activités.
The installation of these sediments was carried out in an oxidizing environment. Generally the velocity is still low in impermeable and little porous clay. Benin basson Western Nigeria Offshore Basins: 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.
The petrographic correlative analyzes of the solid material in stone-line allowed to determine their origin. Triassic strata belong to a platformal succession of mixed siliciclastic, carbonate, and evaporite sediments deposited along the western portions of the basin. H – Cement geochemistry of photozoan carbonate strata upper carboniferous-lower PermianFinmark carbonate platformBarents Sea.
Triassic strata continue to offer attractive exploration targets, as shown by recent activity at Valhalla, Spirit River and Grande Prairie. 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. It reveals that two deposits phases occurred during the carbonate sedimentation. 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.
The limestone is fractured, so more porous than clay and marl.
Oh no, there’s been an error
Selon Pothin et al. The Triassic succession contains a total discovered in-place volume of x m3 raw gas reserves in 10 mature and 2 immature plays. 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. 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 sedimentsire adopted for this basin was a mixed variant of various Southern Nigerian basins nomenclatures.
Les couches argileuses ont une vitesse sedmientaire faible.
Contribution de Sonatrach, Division Exploration: This publication is a translation of 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 bassih variations rocks were studied.
Statistical analysis of the mature plays indicates that a total of 13 plays are likely to exist.
The sonic log fluctuations in the limestone stage reflect the heterogeneity of deposits. There are more or less dolomitised layers alternating with more homogeneous chemical baesin benches, biogenic limestone debris of organisms and past clay. By against certain layers are poorly penetrable and show the presence of fluid.
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.
Three of these plays are predicted to contain over one half of the remaining gas potential: 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. This is a preview of a remote PDF: 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 marine, deep marine with restrictive sedkmentaire circulation and ends with open deep marine conditions.
The first phase of sedimentation is at the origin of the deposit of the extra formational sediments and the second phase is responsible for seimentaire deposition of intraformational sediments. The gamma ray log varies significantly in limestone phases reflecting the heterogeneity of deposits.

Schlumberger Educational Service, Houston Texas: E – Formation evaluation: The thickest deposits, and most of the oil and gas, occur in the westward thickening and deepening depocentre called the Peace River Embayment.
