Sohag – Ammar Abdel Wahid:
Today, Saturday, a committee of professors from the Faculty of Science, Sohag University, inspected the site of the water well, which continued to burn for about 40 hours in the desert area in the village of Beit Kahfil in the district of Gerga, south of the governorate, to inspect and prepare a detailed report.
The report stated that the area in which the well is located contains two types of rock formations ranging in age from the “Eocene III era”. This sequence consists of the Dunka area in Asyut and consists of fossil limestone rocks, which are sediments of marine origin and are composed of thick calcareous deposits containing many Of cracks and fractures, and its thickness ranges between 130 and 200 meters.
The report explained that it also consists of the “Fourth Pleistocene Fourth Time” sequence, consisting of fine siliceous fragments (sand, silt, clay), intertwined with medium to coarse-grained sand deposits that increase in thickness to the bottom, and topped with a cover of chemical limestone (travertine) ), Which are sediments that were formed in shallow lakes during the stages of the Nile River formation, and their thickness ranges between 100 and 200 meters.
The committee’s report indicated that a study was conducted in 2001 on the West Sohag region, from Al Kamil in the north to Awlad Salama in the south, by a team from the Geology Department, and this study showed the possibility of petroleum reservoirs due to the presence of a deep sedimentary basin, and the thickness of the sedimentary cover ranges between 1200 to 1500 meters, as well as the existence of subsurface geological structures such as normal faults and convex folds, which are considered among the most important petroleum fisheries.
The committee stated that it was found that the fire ignited a gas that was under pressure with quantities of water surrounding it.
The committee also clarified that there are two possibilities for the presence of this gas:
The first possibility:
It is a gas leakage from hydrocarbon reservoirs, the possibility of its presence in the oily clay rocks that follow the Dakhla Formation of the upper Cretaceous time, which is located at a depth of approximately 600 to 800 meters, and the leakage occurs upward through the cracks and breaks in the rocks above it and collects in the sandstone layers of the fourth time Until it reached the aforementioned site, which is therefore a gas of petroleum origin and must consist of natural petroleum gases.
The second possibility:
It is a gas produced by the decomposition of plant materials and trees that were buried millions of years at a depth of about 200 meters under the surface of the earth. It is methane “CH4” gas associated with coal deposits, which is a highly flammable gas, and when the auger was digging, the temperature reached more than 50 degrees Celsius, In addition to the heat resulting from friction, this gas exploded, as happens in coal mines, which led to the expulsion of the water present with it as soon as the drilling hole reaches it, and this gas is not a natural petroleum gas.
The committee composed of professors of geology and chemistry at the Faculty of Science, Sohag University, recommended by Dr. Khaled Abdel Ghaffar, Minister of Higher Education and Scientific Research, to quickly drill two test wells toward the parallel south and west toward the plateau from the indicated well, in order to accurately describe the core rock samples and monitor the potential presence of gas And the work of deep reflective seismic surveys through oil companies to accurately study the stratigraphic sequence, as well as the subsurface geological structures and the possibility of the presence of hydrocarbons in it.
It is worth noting that the committee included Dr. Ahmed Aziz Abdel Moneim, Professor of Ground Water, Department of Geology, and University President, Dr. Kamal Muhammad Al-Sayed Khalil, Professor of Inorganic Chemistry, Department of Chemistry and Dean of the College of Science, Dr. Abdel-Basit Muhammad Abu Deif, Professor of Geophysics, Department of Geology, and Vice Dean for Community Service Affairs. Environmental Development, Dr. Farouk Abdel Rahman Mahmoud, Emeritus Professor of Geophysics, Department of Geology, and Dr. Tawfiq Muhammad Mahran, Professor of Sedimentology, Department of Geology.
Last Thursday, the desert area in the village of Beit Khellaf, the department of the Gerga police station, south of Sohag governorate, witnessed a fire in a water well, and the flames escalated at a height of about 7 meters, and they continued to burn for about 40 hours, after which the Civil Protection Forces succeeded in extinguishing them.
