high-temperature high-pressure stability and a long service life. It can increase the rock-breaking capacity of PDC bits and relieve thetorsional vibrationor strings and the slippage of bits. In Well YB10-2H, domestic PDC bits & screw rods were used in the Upper Shaximiao Fm to the upper...
2.2. Sulphate in granitoid groundwaters In deep crystalline rock groundwaters, sodium-chloride salinity increases with depth, and water-rock interaction elevates the Ca/Na ratio (Bucher and Stober, 2010; Bottomley et al., 1994; Stober and Bucher, 1999; Brady et al., 2019). The sulphate cont...
The migration system, as the primary medium linking source rocks and traps, plays a vital role in studying hydrocarbon migration, accumulation, and reservoir formation. This study focuses on Late Paleozoic source rock (mudstone and coal rock) and sandstone samples from the Ordos Basin. By analyzing...
West Nile virions are ~50 nm in diameter with icosahedral symmetry and consist of a spherical nucleocapsid surrounded by an envelope [2]. WNV was first isolated in 1937 from a woman in the West Nile district in Uganda [3]. In the 77 years since its discovery, the virus has expanded to...
The Zhijing-Ansai area is located in the south central part of the Ordos Basin, mainly including Wuqi County, Zhidan County and Ansai District. Tight sandstone reservoirs with low porosity and permeability are mainly what has developed in the study area [1,2,3,4,5]. In recent years, ...
[28], until it became part of the Freiberg Mining District Water Balance (FMDWB) network in 1882 [29]. The entire area around the BSP is characterised by a flat relief and the former mining industries of both the Freiberg and the Brand mining districts [27,30]. Mining explorations ...
For our analysis, we clipped the dataset to regions where more than 0.02 GJ/m2/a are needed and combined them into a 1000 × 1000 m area resulting in a minimum heating grid capacity of ~5 GWh/a, as this is assumed to be a suitable size for modern district heating systems. As can ...
