This dataset is a market activity representing the consumption market of the region. The dataset includes transport, freight from the gate to the point of consumption, and transport services are calculated based on the transportation situation of the product in the region. This dataset represents the product inventory from cradle to gate. The dataset includes thickened oil and unthickened oil offshore production. In China, thickened oil accounts for 10% of petroleum production, and unthickened oil accounts for 90%. This dataset can represent the average production mix in China. thickened oil reservoirs refer to those where the viscosity of the stored petroleum exceeds 50 mPas under reservoir conditions. The petroleum in thickened oil reservoirs has high viscosity and poor fluidity, making it difficult to exploit; low-permeability oil fields have low permeability and low abundance in the oil layer reservoir, and low single-well production capacity. The net calorific value of petroleum is 43.4 MJ/kg, and the average calorific value of natural gas is 36 MJ/Sm3.
