Long‐term fracture conductivity in tight reservoirs

  •  1 March 2024

Graphical Abstract

Description unavailable

The fracture conductivity decreases with the increase of displacement time under the displacement of formation water and fracturing fluid, and the decrease of fracture conductivity under the displacement of fracturing fluid with time is greater than that of formation water displacement. The conductivity increases with the increase of sand concentration, proppant particle size, and elastic modulus, and decreases with the increase of closure pressure.

Gas desorption law of coal particles and calculation method of gas loss during fixed‐point closed sampling

  •  28 February 2024

Graphical Abstract

Description unavailable

In this study, gas desorption during the fixed-point closed sampling (FPCS) was analyzed. The gas desorption law during FPCS was compared with that under atmospheric pressure. The results show that Sun's formula can effectively characterize the gas desorption law during FPCS. A method for calculating gas loss during FPCS by using Sun's formula was proposed. The research findings are expected to provide a theoretical basis for the accurate measurement of coal seam gas content by means of FPCS.

Study on open‐hole extended‐reach limit in horizontal drilling with wavy wellbore trajectory

  •  27 February 2024

Graphical Abstract

Description unavailable

Drilling a series of wavy wellbore trajectories has emerged as a promising operation, offering significant advantages in enhancing reservoir contact. Extending the length of these wavy trajectories requires careful consideration in terms of safe drilling practices, as the pressure management associated with these intricate trajectories has been seldom explored.

The influence of blade curvature radius on the internal unsteady characteristics of a centrifugal pump

  •  27 February 2024

Graphical Abstract

Description unavailable

On the basis of the hydraulic design of IS 80-65-160 centrifugal pump, the whole flow channel numerical simulation of the centrifugal pump is carried out. The influence of different blade curvature radii on vibration and noise of the centrifugal pump is studied. The proposed optimisation method based on the blade curvature radius to improve the internal characteristics of centrifugal pumps can effectively improve the pump efficiency and reduce the flow-induced vibration noise.

How green is blue hydrogen?

  •  1676-1687
  •  12 August 2021

Graphical Abstract

Description unavailable

Blue hydrogen is the production of hydrogen from natural gas combined with carbon capture and storage. Commercial production so far is limited to just two facilities, but blue hydrogen is increasingly being promoted as a green, “low emissions” fuel. Here, we provide the first full lifecycle assessment of emissions from the production of blue hydrogen, including fugitive upstream methane emissions from the natural gas that is used. Far from being low carbon, we find quite large emissions that give blue hydrogen a larger greenhouse gas footprint than any fossil fuel.

Solar power technology for electricity generation: A critical review

  •  340-361
  •  28 September 2018

Graphical Abstract

Description unavailable

In this paper, both methods of electricity generation are reviewed and compared. Based on published studies, PV-based systems are more suitable for small-scale power generation. They are also capable of generating more electricity in a specific area in comparison with CSP-based systems. However, based on economic considerations, CSP plants are better in economic return.

Current status, challenges, and policy suggestions for coalbed methane industry development in China: A review

  •  1059-1074
  •  17 May 2019

Graphical Abstract

Description unavailable

In this paper, the main problems hindering CBM development in China are discussed to provide management suggestions for the government. These key problems include exploration and development techniques, the overlap of mining rights, management, financial supporting policy, investment environment, regulations, and market conditions.
