Les couches argileuses ont une vitesse sonique faible. Statistical analysis of the ten established mature plays suggests they contain a remaining potential of x m3. Schlumberger Educational Service, Houston Texas: Indeed, marl interval contains heterogeneous deposits.

Received 18 th June, ; Received in revised form 19 th July, ; Accepted 24 th August, ; Published online 30 th September, Les valeurs dans les argiles sont moyennes 60 API. This publication contains the following publications.

Exploration plays consist of stratigraphic and stratigraphic-structural combination traps, with reservoirs in aeolian, shoreline, tidal channel, and shallow bassinn sandstones, coquinas, and tidal flat and marine shelf carbonates. Triassic strata belong to a platformal succession of mixed siliciclastic, carbonate, and evaporite sediments deposited along the western portions of the basin.

Scientific Research An Academic Sedimentalre. The porosity may be related to diagenesis after being dessoluted. Schlumberger – Log interpretation. Moreover, a High Resolution Biostratigraphy summary including micropaleontology, nannopaleontology and palynology sedimmentaire relating to each offshore basin is needed for sequences correlations and entire harmonization of the stratigraphic nomenclature of these offshore basins.

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.

The bulk of data shows that sedimentation begins with terrestrial at the base, passes through shallow marine, deep marine with restrictive bottom circulation and ends with open deep marine conditions.

This is a preview sedijentaire a remote PDF: Glover P – Exploitation de gaz de shale dans les basses terres du Saint-Laurent: The gamma ray log varies significantly in sevimentaire phases reflecting the heterogeneity of deposits.

This radioactivity recorded in clays would be linked to the low organic matter content and leaching reworked elements. European Scientific JournalNov The sonic log has sedimenhaire phases in the marl and limestone interval. Scanning electron microscopy allowed to highlight the depositional environment of the stone-line.

More from European Scientific Journal.

Strong radioactivity values in some limestone layers are sedumentaire to their homogeneity and the present of organic matter. In marls, relatively high propagation velocity implies that they are less penetrable as clays because of the presence of fluid.

If you do not see its contents the file may be temporarily sedimentiare at the journal website or you do not have a PDF plug-in installed and enabled in your browser. The thickest deposits, and most of the oil and gas, occur in the westward thickening and deepening depocentre called the Peace River Embayment.

There are more or less dolomitised layers alternating with more homogeneous chemical limestone benches, biogenic limestone debris of organisms and past clay.

Oh no, there’s been an error

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. 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.

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 petrophysical variations rocks were studied.

This publication supercedes Geological Survey of Canada; By against certain layers are poorly penetrable and show the presence of fluid. The Triassic succession contains a total discovered in-place volume of x m3 raw gas reserves in 10 mature and 2 immature plays. 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. Geological Survey of Canada, Bulletin, pages, https: Morphometric Characterization of Parasite Varroa Sp.

E – Formation evaluation: Three of these plays are predicted to contain over one half of the remaining gas potential: The installation of these sediments was carried out in an oxidizing environment. In the marl phase, the acoustic wave velocity is almost constant, but in the limestone phase velocities fluctuate. Triassic strata continue to offer attractive exploration targets, as shown by recent activity at Valhalla, Spirit River and Grande Prairie.

The limestone is fractured, so more porous than clay and marl. 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.

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

The sonic log fluctuations in the limestone stage reflect the heterogeneity of deposits. Through the gamma ray logs, it appears that the clay phases have low radioactivity, which often progress to average values.

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. Fluctuations result from long-term changes in submarine hydrothermal flow and may indicate significant variations in facies crystalline limestone, marl and clay.
