Oil and gas are strategic, non-renewable natural resources and are vital commodities. It is explained that upstream business activities are business activities that are cored or rely on exploration and exploitation. While downstream business activities are business activities whose core are in processing, transportation, storage and/or commercial business activities. At present, 68% of the world's energy needs are derived from fossil fuels. Fossil fuels that are often used include coal, petroleum and natural gas. The results of the 2007 Intergovernmental Panel on Climate Change (IPCC) study showed that the concentration of CO2 gas in the pre-industrial period amounted to 278 ppm, while in 2005 it was 379 ppm. The consequences of this change are rising global temperatures by 0.74C, and there has also been a sea-level rise of 0.17 m, then there has also been a 7% reduction in snow cover in the northern hemisphere and rivers experience slower freeze. The contribution of greenhouse gas emissions from the oil and gas sector is expected to increase from 122 metric tons (Mt) of CO2 in 2005 to 137 metric tons (Mt) of CO2 in 2030. Emissions produced by crude oil exploration in 2015 amounted to 48,947.35 tonnes of CO2e and increased in 2016 amounting to 232,950.30 CO2e. Therefore, an LCA study is needed as a solution to reduce the emissions of greenhouse gases CO2, CH4, N2O, NOx and SOx at a company in East Java. The purpose of this study is to determine the environmental impacts generated by crude oil exploration. The emission data of CO2, CH4, N2O, NOx and SOx, mass balance, the amount of raw materials, fuels used and emissions produced in each of the main process units and supporting units, as well as data on the amount of products produced from petroleum production activities in one company in East Java, are used to determine the impact on the environment that would arise through the stages of LCA analysis using the Eco Indicator 99 method in the SimaPro 8.5.2 software. The results obtained from this study revealed that the process which has the highest impact value on the environment is the process of producing oil in the PV-9900 separator unit, with an impact value of 12620 MPt and the value of each category of damage was 4,76 1011 MJ surplus for the "resources"category, 0,00118 DALY for the "human health"category and 0,0847 PDFm2year for "ecosystem quality"category.
