Evaluasi Pekerjaan Stimulasi Greenzyme Sebagai Upaya Peningkatan Produksi Sumur Minyak Di Lapangan Lenggogeni

As long as the well is produced it can experience a decline in the rate of production, this decrease was caused by the difficulty of oil produced under wet oil conditions.The decline in oil acquisition is a problem that has long been a bottleneck in the oil and gas industry. To increase the rate of production from wells, the age that experiances these problems is carried out by stimulation steps. The method used in stimulation on the Lenggogeni field is the Greenzyme. Appolo Greenzyme method a biotechnology product in the form of a liquid biological enzyme with water soluble protein properties. Biological enzyme is basically a form of catalyst that does not live with protein-based ingredients (Protein-based-non-living catalyst). This method is a field research conducted at BOB PT.BSP Pertamina Hulu. Where this stimulation can change the wettability of rocks that were originally oil wet to wet water. In this study, the stimulation of the 4 wells of (LG #43, LG #68, LG #36 and LG #87). Of the 4 wells, 2 wells (LG #43 and LG #68) that were successful. This can be see from the Qmax and PI. Qmax stimulation was carried out, on well LG #43 was 721,86 Bopd with PI score 4,083. While after stimulation the value of Qmax to 2288,96 Bopd and PI by 12,94. For LG #36 and LG #87 wells it was stated that this failure can be see from the collection of Qmax and PI values from each of the slum cell wells carried out. The as value of LG #36 wells is 1172,49 Bopd and PI is 3,62. After stimulation, the Qmax arrangement was 120,21 Bopd and PI was 0,37
