Abstract :
Oil and gas energy derived from petroleum is the main material for hydrocarbon energy as well as contamination which is a pollutant for the environment. Oil drilling carried out in the área of the sanga-sanga kutai kartanegara field in East Kalimantan is one of the largest petroleum producers on the island of Kalimantan. However, the residual petroleum output tied to the drilling material becomes a contaminant that can pollute the environment. Based on this, information on the distribution of hydrocarbon contamination in the drilling material processing area is needed. The data obtained is in the form of modeling of each trajectory which is then modeled again into 3 dimensions with varying depths. It aims toobtain a picture of the distribution of resistivity values identical to the lithology of the area viewed horizontally. The results of 3-dimensional modeling show that the low resistivity value (<50 Ohm meters) is a swamp deposit in the form of clay and alluvial. The permicable layer is indicated by the presence of a resistivity value above 50 Ohm meters which is indicated in the form of a layer of sand, and is a medium for flowing groundwater and can make a hydrocarbon contamination medium. In accordance with the distribution of resistivity values, it is possible if there is hydrocarbon contamination, only on the west side of point ves (Pd-34) on track three and at point ves Pd-8, Pd-9 Pd-10 on track 4.
