WATER SHUTOFF OPERATIONS IN OIL AND GAS WELLS AND THEIR SOLUTIONS OIL AND GAS

Excessive water production causes numerous economic problems for oil production companies such as affecting the performance of the production wells, shortening their life period, increasing the operating cost, enhancing the presence of scales, corrosion, and degradation in the field facilities. It is very important to distinguish necessary water from unwanted water production since any attempt to reduce good water leads directly to reduction in the oil production. Certain physical and chemical techniques are used as a solution for the elimination and the prevention of water into the wells of different completion type. These methods can be used individually or in combination. Completion types should be considered when designing a water shut-off project. Sprache: Englisch Gewicht in Gramm: 107.
