Résumé : |
The South East Constantine basin looks like a geologically complex area but seemed to important and promising oil potential for oil exploration. This basin was the subject of several studies and research related to several geological topical in the image of tectonics, sedimentology, stratigraphy and including oil interests. However, studies conducted previously also require more expertise can lead a better geological understanding of the above-cited basin.
In our case, study one of the missions to be considered regarding the tectonicsedimentary investigation in the SE Constantine basin with a focus on Coniacien levels Santonian (Upper Cretaceous) and their potential H-C.
The completion of this study required several investigations tools with subsurface data that have been an important contribution.
Several approaches especially sedimentological and tectonic stratigraphic oil interest were discussed. Additional support has been completed from surface investigation.
This investigation was based primarily on geological surveys conducted in the region.
Among the results characterizing the basin SE Constantine and stratigraphically, one could discern that the formations constituting the filling of this basin are training for carbonated dominance with marl alternations. These types of training including characterize Coniacien levels Santonian. This typical lithological dominance was seconded by the geological section of land made in the region (Tamarin - El Kantara) especially in formations of Santonian Coniacien South flank Dj Metlili.
Sedimentary perspective and according to the facies description, this study allowed begun to highlight several types of facies. These facies were determined on the petrographic map: ranging from mudstone to reach the grainstone with typical fauna revealing contents varying energy levels. The Synsedimentary analysis showed the
presence of major sequences optionally composed of Mésoséquence and together may constitute an opening megasequence.
The interpretation sedimentological and faunal content of these facies mainly foraminifera, echinoderms, inoceramids, ostracods and bivalves may be indicative platform sedimentation whose type is ramp.
The lithostratigraphic framework based on drilling wells correlations and data unveiled a relative homogeneity as to the lithological distribution of these constituent formations. According to these correlations, we could see a thickening trend of these levels to the South East Constantine basin center.
On the oil front and a potential evaluation of the rock and its contents, a geochemical database study was introduced. It has been found that in the SE Constantine basin, possibly among the levels of C-H generator, the Late Cretaceous remains promising.
Several rock levels are present with particular geochemical characteristics and also lithological variables. The data obtained was based TOC assessment, maturity, and quality of the rock, revealed a possible generation and accumulation of hydrocarbon potential (oil window) favorable. These H-C were characterized by a find of organic
matter with a type II C.O.T varying between 0.4% and 2.8% with a variable geothermal gradient. The conditions for generating the H-C were changing from one rock to another and from one area to another. These diversifications are related to the conditions of maturity that are particularly pressure and particularly temperaturerelated impacts phenomenal burial and uplift (tectonic-sedimentary effect) that affected the study area.
In the tank, essentially Coniacien level Santonian, its characterization in the South East Constantine basin was established primarily has based logging records drilling data and the description of cores from the study area. Among the findings was contracted as reservoir quality, these reservoirs levels (Coniacien Santonian) with
relatively low petrophysical characteristics: permeability not exceeding 50md and a porosity of up to a maximum of 10%. Similar features can classify ConiacienSantonian reservoir levels as a moderate of up to type (tight). Diagenetic sedimentary effect and also were important impacts in the evolution of these reservoir levels.
