Use of the time-temperature arrhenius index in evaluation the maturity of the organic matter in Siluric and upper Paleozoic rocks in the central and eastern parts of the Aleppo Plateau

considering the importance of temperature and time factors in maturation and conversion the organic materials ,and the facts, that the sum of the effects of these factors is effected by the sedimentary burial history and changes with the changing of the kerogen types,and for consummation the aim of this study in isolating the Siluric and upper Paleozoic rock formations in which temperature and time had allowed to their included organic material to realise its potential in conversion to hydrocarbonic materials, paleotictonic and geotemperature diagrams for these formations were drawn depending on real data from 12 selected drilled wells in the study area, then the values of timetemperature Arrhenius index and the percent of the realised potential in conversion to hydrocarbonic materials were calculated for each main kerogen type (Ia,b,c, II,a,b,c,d, III) which may undergo to the same time-temperature history of the studied formations.

Study of the temperature effect, pressure and geological times on the sedimentry rock in the Palmyrian folding zone the isolation and posipole hydrocarbonic formations

Considering the importance of the Palmyrian folding zone as one of the promising zones, and the scientific and practical importance of the isolation of the matrix formation in any sedimentary basin or in any part of it, and that the sedimentary rocks, which have sufficient quantity and quality of organic materials cannot become matrixes until they undergo convnient conditions of temperature, pressure and geological time, the aim of this work is to study the effect of these factors on the sedimentary rocks of the investigated ones and to isolate the formations, which may be matrixes. According to the results of this study,the formations which may play the main role as matrix are these which have Middle Triassic age or Paleozoicin the northern Palmyrian subzone, and older than Permian age in the southern Palmyrian subzone .

The use of sonic method in the detection of petroleum reservoirs in Syrian oilfields ( Jubiseh)

The use of sonic method to detect reservoirs with secondary porosity (fissures and cavities) was due to the high effect of this porosity on the elastic waves. The generalization of the experimental results helped to construct a diagram to be used in detecting reservoirs with secondary porosity in the wells. A joint analysis of the data of the sonic method and other well logging methods, such as boreborehole diameter log, natural radioactivity log, natural log and micro and deep resistivity log...etc, was achieved. The wave spectrum was analysed for a relatively long period so that it included Lambi waves. The detection of these reservoirs was achieved by using the correlation between all available results, which led to the determination of the presence of the secondary porosity and the suggestion of a new calculation method. In addition to the secondary porosity some other factors which affect the sonic measurements were mentioned.
