Oil and gas production
Oil extraction services where the location of oil and its fields are determined: geologists resort to relying on seismic surveys to explore the oilfields, and geologically appropriate geological locations for the installation and formation of oil reservoirs. Of information on the geological structure of the destination area, and other methods adopted at this stage measure gravity, and measure magnetism. Drilling the wells to reach oil: This phase of the process of extraction and extraction of oil to drilling oil wells by creating a hole deep and long in the depths of the earth by a special tool called oil platform; researchers are working to install a tube made of steel in the artificial hole to complete the extraction process and an integrative assertion And the oil begins to pass through these holes after being fixed at the bottom of the well and stability in the base, and at the top of the hole is put the so-called "Christmas tree" consisting of pumps and valves connected to each other to control the process of pressure and the flow of oil from its sources. Extraction and extraction of oil: This phase includes two basic steps: Preliminary extraction: At this stage work on stimulating the oil reservoir depending on a set of natural mechanisms; where the oil is withdrawn from the well and put natural water in place, and then move to the stage of gas deployment and raise it to The peak of the tank and the transition to the phase of the diffusion of dissolved gas in crude oil and the elimination of gravity caused by the movement of oil between the upper and lower parts of the reservoir where the wells, the extraction rate at this stage between five to fifteen percent. Secondary extraction: As time progresses on the life of the oil well, the pressure factor gradually decreases until it reaches a point of decline where the force of the ground pressure is unable to move the oil and throw it towards the surface. Geologists use secondary methods of extraction by injecting oil tanks with water to lift The ability to pressure and stimulate it, and stimulate natural gas wells to increase the gas lift by injecting carbon dioxide or air at the bottom of the active gas well; it reduces the level of density of liquid material in the well, and the extraction rate to 30 percent.
