Research on the waste energy and emission has been quite intensive recently. The formation, venting and flared the Boil-off gas (BOG) considered as one of the contribution to the Greenhouse Gas (GHG) emission nowadays. The current model or method appearing in the literature is unable to analyze the real behavior of the vapor inside Liquefied Natural Gas (LNG) tank and unable to accurately estimate the amount of boil-off gas formation. In this paper, evaporation model is used to estimate LNG Boil-Off rate (BOR) inside LNG tank. Using User Define Function (UDF) hooked to the software ANSYS Fluent. The application enable drag law and alternative heat transfer coefficient to be included. Three dimensional membrane type LNG cargos are simulated with selected boundary condition located in the United States Gulf Coast based on average weather conditions. The result shows that the value of BOR agrees well with the previous study done with another model and with International Marine organization (IMO) standard which is less than 0.15% weight per day. The results also enable us to visualize the LNG evaporation behaviors inside LNG tanks.

Natural gas resource of Es1 layer in Yangxin subsag is very abundant. Natural gas formation, enrichment conditions and regularity are analyzed in this paper. Geochemistry analysis shows that natural gas resource of Es1 layer in Yangxin subsag belongs to biological origin gas. The sedimentary environment, ground temperature, gas source rock and preservation condition of the study area is advantageous, which provide a guarantee for natural gas generation and preservation. Research shows that natural gas enrichment in the lower part of Es1 layer because of limestone reservoir development, and on the horizontal direction natural gas is mainly enrichment in the eastern nose structure zone and southern slope zone. The both zones are the preferred zone for natural gas exploration in the study area.
