As evidence, coal-gas outbursts occurred in the coals from the Tao’er mine in Hebei ,province,, China, and the Xiayukou mine ,in Shanxi province,, China, in 2007 and 2011, respectively. These coals were both formed in the Carboniferous-Permian period, with both having low tensile strength and a low performance index .

Results indicate that the ,fracturing fluid, filtration has a great impact on the ,flowback, performance and later gas prodn. Results suggest that increasing the filter cake thickness decreases the gas prodn. peak value, and delays the time showing the peak of gas prodn., and further reduces the cumulative gas prodn.

In addition, the fracturing ,fluid, of 10 ml was sampled during the experiments at 24 h, 48 h, and 72 h, which were used for measuring the pH value. After reaction, the shale samples were taken out of the fracturing ,fluid,, cleaned using ultrapure deionized water, and then dried at the condition of 50°C for 12 hours in the oven.

18/5/2020, · In this section, the proposed mathematical tool was applied to match the CBM production data from a vertical well in the south of Shanxi Province, China (Ma et al. 2017). Initially, approximately 320 m 3 of pressurised water was injected into the coal seam for hydraulic fracturing to improve the connectivity to the well and increase the permeability of the reservoir.

Toward this end, this paper presents a case study in Ningqiang County, ,Shanxi Province,, China. Slope units were selected as the basic mapping units. A traditional statistical certainty factor model (CF), a machine learning support vector machine model (SVM) and random forest model (RF), along with a hybrid CF-SVM model and a CF-RF model were applied to analyze landslide susceptibility.

Measures taken to process these ,flowback, fluids include 1. reinjecting them underground using re-injection wells; 2. reusing them for hydraulic stimulations after simple treatment; 3. treating them into fresh water. The abundant chemical additives make the processing of ,flowback fluid, difficult and costly.

This winter and spring, the reservoir was the capital’s lifeline. No rain or snow fell in Beijing between October 23rd 2017 and March 17th 2018—by far the longest drought on record. Yet the city suffered no supply disruptions, unlike ,Shanxi province, to the west, where local governments rationed water.
