This dataset is a market activity representing the consumption market of the region. The dataset includes transport, freight of the product from the plant gate to the consumer, and the transport service is calculated according to the transportation conditions of the product in the region. This dataset represents the life cycle inventory of the product from cradle to gate. The dataset encompasses multi-technology which includes water injection drive and gas injection drive technology, where in China, the proportion of natural gas production technology is 80% water injection drive, and 20% gas injection drive. Therefore, this dataset can represent the average production mix in China. Waterflooding technology: As an important method to improve the recovery rate of oil fields, waterflooding increases formation pressure and pushes petroleum towards the wellhead by injecting water or other fluids into the oil layer. \nGas injection technology: As a gas injection process to enhance oil recovery, it involves injecting a working agent (natural gas or air) into the reservoir through a series of injection wells, thereby driving residual petroleum into surrounding production wells. \nA low-permeability oil field refers to an oil field with low permeability, low abundance, and low single-well production capacity in the reservoir. The net heating value of petroleum is 43.4 MJ/kg, and the average heating value of natural gas is 36 MJ/Sm3.
