Technical and Environmental Study of Acid Gas Reinjection into SEEPAGE bed in an Oil & Gas Field of Erbil Governorate
Sour gases are nowadays becoming a focusing issue for environmental agencies consideration in oil and gas projects. As these gases mainly consist of H2S and CO2 and are part of the solution gas within the hydrocarbon reservoirs naturally. These two gases are also killer gases, that is why usually in the past or at the begging of petroleum and gas industry, flaring process was relied on to release from them and this called conventional method, but this method is bringing more concerns and issues to the environment, because flaring cannot make these gasses to be environmentally friendly.
In Kurdistan region, the technology of extracting oil and gas from the subsurface is just been constructed and in almost all the fields this conventional method is followed to release from gases. This paper presents the new technology available in some developed countries to reinject the sour gas into a formation that can seal the injected gas in a way that not allow to emit into the atmosphere and/or underground water. This new technology simply compressing the sour gas and then reinjecting into the pre-studied and selected zone.
In Kurdistan region, some zones are compatible for performing the same technology, for example, in this paper the FSP field is been studied and according to the geological data and description Seepage bed can be a good candidate zone for reinjecting the sour gas into it.
Additionally, in this paper, an intensive environmental and economic analysis is made for a field due to confidentiality it is named here as FSP Field, where calculation is made on the amount of gas been flared from the begging and the effect of this flaring on environment. At the same time, a zone is geologically studied and chosen for reinjecting the sour gas.
Finally, persuasive recommendations are launched to generalize this new technology in this region through a scientific way to avoid more poisoning the clean atmosphere.
