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…
Field-pipelines leakage detection based on the negative pressure wave theory is mainly aiming to effectively process pressure sample signal in time domain. Previous methods often perform well for detecting large leakage but poorly for small leakage.…
This paper focuses on the application of steady-state operability to Model Predictive Control (MPC) of the Shell Heavy Oil Fractionator (SHOF) control problem. Operability for non-square systems is a relatively new area in the literature, and…
With the improvement of Micro-Electro-Mechanical Systems(MEMS), which include miniature structure, miniature sensor, actuator, control circuit, communication, and power supply in one or more chips, the Functionally Graded Materials (FGMs) gradually…
Monitoring oil stocks provides valuable insights on the balance between production and demand of petroleum products. The identification of oil depots is important for estimating storage capacities and measuring oil stocks. To achieve this purpose, we…
Because of complex geo-conditions, many caverns by solution mining in bedded salt rocks have different irregular shapes. To verify the feasibility of using irregular-shaped caverns for underground gas storage (UGS), four typical cavern-shapes are…
Taylor slug flow commonly occurs in crude oil pipelines, mini-/microreactors, space propulsion thrusters, heat exchangers, and nuclear reactors. The flow is an intermittent gas regime which occurs in flowing liquid inside pipelines and capillary…
With the improvement of Micro-Electro-Mechanical Systems(MEMS), which include miniature structure, miniature sensor, actuator, control circuit, communication, and power supply in one or more chips, the Functionally Graded Materials (FGMs) gradually…
Assuring the reliability of crude unit pipelines in the downstream oil and gas industry is highly essential since unexpected failures of these pipelines can result in a number of negative impacts to the business, including safety, environmental, and…
Chemical herders are a promising technique for treatment of oil spills in icy waters at high latitudes. However, obstacles on the water surface such as floating ice affects or interferes with all spill response countermeasures including chemical…
