In recent years, polymer flooding has become a mature technology to improve the reservoir recovery rate and has been successfully implemented in many oil fields. Because of high operating costs of a polymer flooding project and the impact to the…
The deep-water gas field in the South China Sea has been officially put into operation, but due to the strong energy of the bottom water in the offshore gas field, the production well is prone to water flooding, resulting in a serious decline in gas…
This paper proposes a novel approach based on deep learning to improve oil reservoirs' history matching problem. Deep autoencoders are widely used to solve the oil industry problems. However, as the input data increases, the autoencoder parameters…
Temperature and pressure variations have important significance in environmental protection and safety operation of oil reservoir in salt caverns. Shrinkage of salt caverns, effect of permeability and fluid thermal pressurization rate were discussed…
The determination of gas well productivity is the basis of scientific and reasonable development of gas fields and has important guiding significance for gas well production allocation. According to the change of gas-water two-phase seepage law, the…
Titian gas field has about 100m3/d gas condensate that is require to be transported to Pinghu integrated platform, then transported to Daishan terminal through Pinghu-daishan 16" oil sea tube. The platform is without storage means, Pinghu-daishan 16"…
To fully utilize the abandoned salt cavern resources and to increase the total amount of the fossil energy reserve of China, reconstructing some of these salt caverns for underground gas storage (UGS) or strategic petroleum reserve (SPR) would be an…
In-site permeability test was carried out in order to find the permeability coefficient in the ground of the 7 companies (Research Institute of Petroleum Industry, Oil Exploration Operations Company, Commercial Storage, Iranol Company, Distribution…
Natural gas purification is a challenging task due to the existing number of contaminants in the mixture. Sour natural gas, in particular, presents an even higher challenge due to the presence of the highly toxic hydrogen sulfide (H2S) gas. These…
For developing unconventional oil and gas resources, it is necessary to quantify the heterogeneity embodied in both pore-size distribution (PSD) and pore spatial distribution, on the basis of which the relationship between the seepage characteristics…
Salt rock is a potential medium for the underground storage of hydrocarbons and nuclear waste. In China, salt deposits are typically composed of layered rocks, usually sandwiched by insoluble interlayers. These salt rock–gypsum interlayers…
The study reports obtaining, characterization and evaluation of the preservation efficacy of nano-Ag-graphene-TiO2-polylactic acid (PLA) film during the storage of the curd cheese. The reusability of the active package was also evaluated. The…
In this paper, the impact of CO2-carbonate interactions on hydrocarbon recovery from three initially oil-saturated heterogeneous carbonate core samples (with low and mid permeabilities) were investigated. Alternate injection of carbon dioxide (CO2)…
This paper examines the usefulness of using reactive powder concrete (RPC) as a better option for constructing crude oil tanks. The effect of 2 types of crude oil products (kerosene and gas oil) on the structural behavior of RPC and normal strength…
In this study, a series of laboratory tests were performed to investigate the interaction between crude oil, clay minerals, and sand particles in contaminated soils and the effect of crude oil on the engineering properties of sand-kaolinite mixtures…
