Optimization of Waste Pit Treatment Using The TAPIR Method in Tanjung Field, South Kalimantan

Abstract

Pertamina EP Tanjung Field is engaged in the upstream oil and gas sector with oil and gas exploration and production activities where there is produced water that arises from these activities. The produced water is pumped to the WIP (Water Injection Plant) facility, then all produced water is injected into the well. injection as pressure maintenance (zero discharge program). The need for clean water for injection water is an average of 89,632 barrels in 2020 so that quite a lot of water is needed from the Clean Water Treatment Plant (WTP) facility owned by PEP Tanjung Field. In addition, there are fluids from outside the process of existing production facilities such as cellars, rig activities, workshops and other supporting activities that enter the fluid separation facility and then the separated water is discharged into the environment. The fluid separation activity from outside the process of the existing production facility has not been maximized so that the amount of B3 waste resulting from the separation process is quite large.

One of the efforts that can be done to overcome this problem is to use the TAPIR Method (Accommodate, Sediment, Separate, Transfer) where with this method modifications are made to the fluid separation process and also the waste pit building. Discharged into the environment and can be useful in increasing the volume of water that can be injected into the injection well facility because it already uses a zero discharge system by modifying the Waste Pit facility minor. This method has proven to be effective and useful to help with the problem of injection water requirements and reduce the production waste.
