This paper analyzes and summarizes the oil and gas market's development in 2022 and its trend in 2023.The world's proven oil and gas reserves increased slightly in 2022.The investment in oil and gas exploration and development was weak, as the amount of investment in exploration had increased when compared to 2021, but had not yet recovered to the level before the COVID-19, and the lease rounds of oil and gas exploration blocks and the M&A activities of oil and gas resource had decreased substantially.Throughout the year, oil and gas prices varied significantly, exhibiting a highs and lows alternating pattern.The global oil and gas supply capacity had weakened, particularly the natural gas supply, which had decreased this year.The global demand for oil and gas was low, and the demand for oil and gas in a number of places had decreased dramatically.Margins, refinery utilization rate and refinery throughput of the global oil refinery operations gradually increased.With the global political environment predicted to improve by 2023, it is anticipated that investments in oil and gas exploration and development will increase steadily.Oil and gas prices may decline in the short term and rise in the long term due to changes in the economy and the supply and demand balance for oil and gas.Under the influence of sanctions and anti-sanctions measures of Russia and western nations, OPEC+ production reduction agreement, etc., the oil and gas supply and demand market is likely to reach a tight balance.Under the influence of the 2022 improvement, the tension on the refining market will gradually alleviate.
