... Abstract Supercritical carbon dioxide fracturing technology, as the main representative of water free fracturing technology, has unique advantages and broad application prospects in the development of shale oil and gas reservoirs. Supercritical carbon dioxide fracturing technology has low...

... the technology to be underdeveloped. Our work suggests that careful implementation of flue gas injection can help accelerate carbon sequestration deployment. This study focuses on the disparity in solubility among flue gas components. As CO 2 dissolves into reservoir brines at higher rates than N2 or O2...

... area between the wellbore and reservoir. Therefore, the field tests of horizontal well re-fracturing were carried out in Jimsar shale oil reservoir. However, it varied in effect. In this paper, based on the engineering parameters of primary fracturing, a fuzzy evaluation model was established firstly...

... Abstract Low-porosity, extra-low-permeability tight sandstone oil and gas reservoirs have become an important research area for hydraulic fracturing. Sand-mud interlayer is often developed in this type of reservoir in the longitudinal direction. The heterogeneous distribution of oil layers...

... ABSTRACT: The fractured-vuggy carbonate reservoirs are widely distributed in North American and west of China. According to statistics, there have more than 70 fractured-vuggy reservoirs in the world. The logging data shows that the diameters of vugs are between 0.15-15 meters, several times...

... ABSTRACT: In order to optimize the strategy of water injection before re-fracturing of Mahu glutenite reservoir in Junggar Basin, a series of numerical model are established by commercial reservoir simulation software based on field data. A production history match is completed, confirming...

Pressure buildup from injecting 1 million tons per year (Mtpa) of CO 2 through one well versus injecting 5 Mtpa CO 2 -N 2 through five wells drilled in a two-one-two well pattern is compared. Pressure throughout the reservoir...
