Abstract

Formation water that is produced from inside the reservoir, must be treated first before being injected back into the reservoir. Utilization of unprocessed produced water that still contains ionic compounds can cause problems in injection wells. Proper treatment will make the produced water can be utilized properly. One way to treat formation water is to use the activated carbon of cassava skin biomass. Making activated carbon from cassava skin biomass is in 3 stages, the dehydration process, the activation process with a variable concentration of 40% HNO3, 50% HNO3 and 60% HNO3 and the carbonization process carried out at 600˚C for 2 hours. Testing of activated carbon for formation water treatment is by immersing activated carbon into formation water samples for 16 hours, 20 hours and 24 hours. The results of activated carbon characterization on the surface morphology of activated carbon using a digital microscope showed that the higher concentration of HNO3 can make the surface area of the pores of activated carbon increase. Activated carbon with a concentration of 60% HNO3 is activated carbon with the best results compared to activated carbon with a concentration of 40% and 50% HNO3. Activated carbon 60% HNO3 produces large surface area and pores so that it is able to become an adsorbent media. Formation water that has been treated using 60% HNO3 activated carbon for 24 hours produces water that is clearer and odorless compared to the treatment time of 16 hours and 20 hours. This shows that the longer the formation water treatment time, the ion compound content and conductivity value will decrease. Then the 24 hour treatment time is the best result of formation water treatment to be reinjected.
