  • Well optimization through downhole water control

    B. Schwanitz and P. L. Jørgensen

    One of the biggest problems facing the oil and gas industry today is that water will eventually encroach on most producing wells and dominate the production. It is estimated that 250 million bbl of water is produced worldwide each day.1 Water production increases as wells mature, so that mature wells (>10 yrs) produce on average, about 9.5 bbl of water for every bbl of oil. During the last decade, global watercut has increased to 75% from about 70%-and this figure is still rising due to maturing fields. Optimizing existing reservoir management methods and introducing new fields may bring the number down. When most of the world’s oil and gas production comes from fields that are more than 30-yr old,2 new solutions are in high demand. The growth in mature fields has led to growth in oil recovery techniques to ensure stable production.
