The difference between the declinations of the two formation-mean directions is 39.4° ± 10.6°, indicating ~40° of clockwise rotation in the Mizunami area between deposition of the Akeyo Formation (18.1 17.5 Ma Chronn C5Dr) and deposition of the Oidawara Formation (15.8 15.7 Ma). Figure 9 shows a rotation versus age plot (data are listed in Table 3).
Or not: the oldest parts of the SWCC likely predate Siletzia, and the nature and location of the contact between these two formations is unknown.
The contact between these two formations is characterized by parallel bedding planes in both, ferruginous alteration at the top of the Ongeluk Formation, and the absence of a basal conglomerate.
Based on the nonlinear model, neural network algorithm is used to identify the relationship between the wave impedance and the three formation pressures (pore pressure, fracture pressure and collapse pressure).
Based on that, the drilling direction can be determined in time according to the polarization angles whether appear on the amplitude ratios and the phase difference curves corresponding to the interface between two formations, then the geosteering drilling information can be accurately provided by resistivity LWD tool.
Generally, we can provide timely geosteering drilling information according to the polarization angles whether appearing on the amplitude ratio curves or the phase difference curves corresponding to the interface between two formations.
The profiles of the four species in both the mainstream and sidestream smoke streams were inter-related during and around the 2-s puff periods, a feature demonstrating the intricate connection between the two smoke formation processes.
Since the 2013 Africa Cup of Nations and throughout the qualifiers, Lamouchi has switched between two formations, sometimes deploying a 4-4-2, more often using a 4-3-3 so as to field as many of his talented forwards as possible.
A number of propagation characteristics have been compared between two formations of hexagonal cladding of our proposed PCF structure.
