| Summary: | In 2016, Indonesia along with 170 other countries signed the Paris Agreement on
Climate Change with a focus on greenhouse gas (GHG) emissions mitigation and
adaptation. PT X (Ltd) is one of the companies engaged in oil and gas exploration
and production in Indonesia. In its mission, PT X (Ltd) stated that oil and gas
discovery, development, and production activities are carried out in safe and
environmentally friendly operations. Action that can be taken to fulfill the mission
and support Indonesia to achieve the Paris Agreement targets is to conduct an
inventory of GHG emissions. In this study, PT X (Ltd)'s GHG emission inventory
is carried out for Field Y where the natural gas exploration and production take
place. The inventory focuses on calculating the emissions of carbon dioxide
(CO2), methane (CH4), and nitrogen oxides (N2O) from three different source
categories. Generally, the sources of GHG emissions in the oil and gas industry
consist of combustion sources, process emission and vented sources, and fugitive
sources. The inventory methodology refers to the American Petroleum Institute
(API) Compendium 2009. The activity data used are secondary data from PT X
(Ltd) and assumption based on global references. The emission factor used refers
to several references from the API, United State Environmental Protection
Agency (US EPA), and others. The results of the inventory are CO2, CH4, and
N2O emissions from each category of emission sources in January-June 2021. It
was found that the largest GHG generated by exploration and production of
natural gas in Field Y is CO2 with the majority coming from the combustion
sources, followed by CH4, and the least is N2O. Mitigation that can be done is the
application of an automatic air/fuel ratio system for gas machine of compressor
and utilization of flare gas until zero routine flaring (ZRF) is achieved. |
