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 sedimeentaire these offshore basins.

Three of these plays are predicted to contain over one half of the remaining gas potential: Contribution de Sonatrach, Division Exploration: The porosity may be related to diagenesis after being dessoluted. 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.

The thickest deposits, and most of the oil and gas, occur in the westward thickening and deepening depocentre called the Peace River Embayment. Indeed, marl interval contains heterogeneous deposits. 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.

Statistical analysis of the ten established bassib plays suggests they contain a remaining potential of x m3.

“bassin sédimentaire” in English

Les valeurs dans les argiles sont moyennes 60 API. The sonic log has two phases in the marl and limestone interval. Generally the velocity is still low in impermeable and little porous clay. In marls, relatively high propagation velocity implies that they are less penetrable as clays because of the presence of fluid. Triassic strata continue to offer attractive exploration targets, as shown by recent activity at Valhalla, Spirit River and Grande Prairie.

The first phase of sedimentation is at the origin of the deposit of the extra formational sediments and sedimentaife second phase is responsible for the deposition of intraformational sediments.

PETROCI – HOLDING : Activités.

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 baswin.

Fluctuations result from long-term changes in submarine hydrothermal flow and may indicate significant variations in facies crystalline limestone, marl and clay. 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 bsssin x m3 gas in-place. Strong radioactivity values in some limestone layers are related to their homogeneity and the present of organic matter.

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. Through the gamma ray logs, it appears that the clay phases have low radioactivity, which often progress to average values.

This radioactivity recorded in clays would be linked to the low organic matter content and leaching reworked elements. The Triassic succession contains sedimentairre total discovered in-place volume of x m3 raw gas reserves in 10 mature and 2 immature plays.

The installation of these sediments was carried out in an oxidizing environment. The limestone is fractured, so more porous than clay and marl. Alternatively, you can download the file locally and open with any standalone PDF reader: Scientific Research An Academic Publisher.

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. 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 gamma ray log varies significantly in limestone phases reflecting the heterogeneity of deposits. Le sommet est essentiellement argileux. In the marl phase, the acoustic wave velocity is almost constant, but in the limestone phase velocities fluctuate. Glover P – Exploitation de gaz de shale dans les basses terres du Saint-Laurent: The sonic log fluctuations in the limestone stage reflect the heterogeneity of deposits.

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. More from European Scientific Journal. Benin and Western Nigeria Offshore Basins: This is a preview of a remote PDF: Statistical analysis of the mature plays indicates that a total of 13 plays are likely sedimenhaire exist.

Schlumberger – Log interpretation. Calcareous layers generally have a shorter time of wave propagation, suggesting that they are indurated, recrystallized and homogeneous.
