Two-phase flow is common in petroleum, process, petrochemical, power, and refrigeration industries (Godbole et al., 2011). There are two types of two-phase flow modelling in the literature (Godbole et al., 2011). In the first category, defined as boiling or thermal non-equilibrium, two ...
This method is also capable of creating high-precision, micro-scale 2D-TMDCs heterostructures by two-step direct laser writing. Results and discussion This method can be envisioned as localised laser-printing of TMDCs. The processing steps are schematically illustrated in Fig. 1a, namely: substrate...
1 and S4–5). In addition, ML trees of trimmed alignments, from which we removed compositionally biased sites to increase tree accuracy for distantly related sequences prior to concatenation, using BMGE85 or Divvier86, were evaluated with the same method (Figs. S6–7)....
Although the above-described sealing elements can be used at any time during the drilling or production of a wellbore, these sealing elements are most often incorporated in downhole tools, such as plugs or packers, placed within a wellbore to isolate production fluid or to manage production fluid...
In January 1901, at 1020 feet, almost precisely the depth predicted by Higgins Wild Gas, the well-roared and suddenly ejected mud and six tons of drilling pipe out of the ground, terrifying those present.1901年1月,在1020英尺深的地方,几乎与希金斯Wild Gas预测的深度完全一致,井喷轰鸣着,突然从地...
(ii) To overcome the shortcomings of the surface parameter detection method, the downhole detection method while drilling was proposed, such as PWD (Pressure-While-Drilling), MWD (Measurement-While-Drilling), intelligent drill pipe, etc (Ward and Andreassen, 1998; Bryant et al., 2004; Bansal ...
and crater wear. For the delamination analysis caused by drilling, two types of delamination are identified (type I and II), and their values were quantified through the equivalent delamination factor (Fed). The results showed that, in general, the process used to apply the coating to the too...
The evaluation of the total absorbed dose for the two analyzed samples was obtained according to the fine-grain technique and the added dose method was used. A list of all examined samples and the techniques employed are summarized inTable 1. ...
This might come as a shock… But we don’t drill oil & gas wells because people we agree with support it or because oil & gas fuel our economy. We drill oil & gas wells to make money. When we start drilling CCS wells, we’ll be doing it for the same reason. ...
