Well completion issues for underground gas storage in oil and gas reservoirs in China

Journal of Petroleum Science and Engineering, 2018
Abstract Underground Gas Storage (UGS) is considered a strategic method to balance the supply-demand chain of the energy required throughout a year and shave the peak demands during the winter time. This paper highlights international UGS distributions including ongoing UGS facilities in China, followed by a review of integrity issues such as fault ...

Study on the Characteristics of Well Completion Technology in Deepwater Oil and Gas Field Development

International Journal of Power and Energy Engineering, 2021
In recent years, China has made certain achievements in shallow sea petroleum geological exploration and development, but the exploration of deep water areas is still in the initial stage, and the water depth in the South China Sea is generally 500 to 2000 meters, which is a deep water operation area.

Selection Criteria for Repurposing Oil And Gas Well to Geothermal Heat Extraction

Day 3 Wed, October 18, 2023, 2023
Oil and gas wells are generally plugged and abandoned when they reach the end of their economic life. Thus repurposing these wells to harness the geothermal energy was supported as a way to reduce the abandonment expenses for the operators and cheaper ...

Some Rock-Mechanical Aspects of Oil and Gas Well Completions

Society of Petroleum Engineers Journal, 1985
Abstract Elementary borehole- and perforation-stability problems in friable clastic formations for unrestricted fluid flow between reservoir rock and underground opening are treated on the basis of linear poroelastic theory. Thermal stress effects caused by a temperature difference between reservoir and borehole fluids can be predicted ...

Concentric Completions of Oil and Gas Wells

Journal of Petroleum Technology, 1959
Introduction This paper discusses the use of 1 ¼-in. tubing placed concentrically inside the normal flow string in both oil and gas wells. The use of this extra string provides an annular space which can be employed to perform a number of functions. The Union Oil Co.

Industrial Implementation of Emulsion-Suspension System with Nanoparticles for Oil and Gas Wells Completion and Maintenance

Abu Dhabi International Petroleum Exhibition & Conference, 2020
Abstract An article presents comparative results of pilot of an innovative blocking pack for well-killing operation – emulsion-suspension system with supercharged nanoparticles (ESS). The ESS is characterized by the following competitive advantages: unlimited compatibility with petroleum reservoir fluids, gases, rocks and well-killing ...
