Description

Visoka oilfield was explored in 1963 through the well G-622. In this oilfield had been drilled more than 170 production wells. Through all this years of its exploitation, mainly because of the outdated technology, the environmental pollution reached really dramatic values. The pollution extends on the Visoka village, affecting so the life for the entire community. The oil spills, the gas emissions and the formation water affected and polluted and ―k illed‖ the Gjanica River, its delta and the Adriatic coast in the Semani beach. Due to the technology and the completely wrong policies, used in the past, the wells had been equipped with a pit, whose actually are filled with oil, water and solid wastes. Now these mixtures are more similar with TAR‘s. This is the main evidence which proves that, the area had never been cleaned up properly. Actually the reservoir had been given in use to a foreigner company, based in a petroleum agreement. The concessionary has already preparing the rehabilitation plan. Based on the best international experience the cleaning up ways will be based on the oil spill treatment, mainly through dispersants, the water treatment through dispersants, filtrations processes and reinjection and the emissions cleaning up mainly through reinjection. The polluted soil will be treated through thermal methods, or will be deposited in a closed landfill. Evaluations, calculations and spatial distribution of the oil spills of the Gjanica River and Adriatic Sea are presented in this paper.

The Surface Distribution of Oil Spills, the Environmental Status of the Visoka Oilfield, Its Rehabilitation Ways: Case Study

Prishtina, Kosovo

Visoka oilfield was explored in 1963 through the well G-622. In this oilfield had been drilled more than 170 production wells. Through all this years of its exploitation, mainly because of the outdated technology, the environmental pollution reached really dramatic values. The pollution extends on the Visoka village, affecting so the life for the entire community. The oil spills, the gas emissions and the formation water affected and polluted and ―k illed‖ the Gjanica River, its delta and the Adriatic coast in the Semani beach. Due to the technology and the completely wrong policies, used in the past, the wells had been equipped with a pit, whose actually are filled with oil, water and solid wastes. Now these mixtures are more similar with TAR‘s. This is the main evidence which proves that, the area had never been cleaned up properly. Actually the reservoir had been given in use to a foreigner company, based in a petroleum agreement. The concessionary has already preparing the rehabilitation plan. Based on the best international experience the cleaning up ways will be based on the oil spill treatment, mainly through dispersants, the water treatment through dispersants, filtrations processes and reinjection and the emissions cleaning up mainly through reinjection. The polluted soil will be treated through thermal methods, or will be deposited in a closed landfill. Evaluations, calculations and spatial distribution of the oil spills of the Gjanica River and Adriatic Sea are presented in this paper.
