Revival of idle wells through adding perforation in matured field
Over 70% of the present world oil production is from brownfield. Nearly 50% of the oil reserves are from 30 giant matured field. With the hard to find huge new oil field in South East Asia, it is exceptionally challenge for this region to keep up its oil production. Consequently, improvement of this...

| Summary: | Over 70% of the present world oil production is from brownfield. Nearly 50% of the oil reserves are from 30 giant matured field. With the hard to find huge new oil field in South East Asia, it is exceptionally challenge for this region to keep up its oil production. Consequently, improvement of this develop field has been, and will progressively be, an alluring subject. Develop field advancement practices can be isolated into two noteworthy group (1) well engineering and (2) reservoir engineering. Well intervention activity has turned into the primary action to guarantee production sustainability and guaranteeing persistent reservoir management strategy is properly captured especially for the low reserves field which endeavouring to reduce the production rate. This study focuses on the well engineering where it will address and discuss the planning and evaluating the work flow applied in bring back life to the wells through adding perforation. Several aspects are taken into consideration including reserves associated with the string; well integrity assessment; Possibility of success; and cost estimation. Consequently, adding perforation in is the most efficient technique in improving production of matured field. This includes the production gain and cost value analysis. In a nutshell, the workflow serves as a guideline and this case serves as reference for future add perforation job in the region. |
