This dataset is a market activity representing the consumption market of the region. It includes transport, freight services from the factory gate to the consumer end, calculated based on the transport situation of the product in the region. This dataset represents a cradle-to-gate inventory of the product. The dataset contains multi-technology including waterflooding and steam drive, with waterflooding comprising 80% and steam drive 20% of petroleum production technology in China, which can represent China's average production mix. Waterflooding technology: As an important means to improve oil field recovery, waterflooding pushes petroleum towards the wellhead by injecting water or other fluids into the oil layer to increase formation pressure. Steam Drive Technology: This technology is primarily used for the development of thickened oil reservoirs. By injecting high-temperature steam into the oil layer, the viscosity of petroleum is reduced, thereby improving its fluidity and facilitating extraction. thickened oil reservoirs refer to reservoirs where the viscosity of stored petroleum is greater than 50mPas under reservoir conditions. The petroleum from thickened oil reservoirs has high viscosity and poor fluidity, which makes it difficult to extract. The net heating value of petroleum is 43.4MJ/kg, and the average heating value of natural gas is 36MJ/Sm3.
