receiver array-filtered seismic data are investigated: (1) point receiver inversion where array effects are neglected; (2) preprocessing of the data with an inverse array filter, followed by point receiver inversion; (3) array inversion, where the array effects are included in the forward ...
Northern latitude and eastern longitude figures are reported in the frame; circles point at ENI/Agip wells (well names in italics). B) Simplified seismic section along the N-S trace in A) (redrawn after Pieri & Groppi 1981): Pg = Paleogene; Mi1-2 = Lower to Middle Miocene; Mi3 = ...
Amplification of in-plane seismic ground motion by underground group cavities in layered half-space is studied both in frequency domain and time domain by using indirect boundary element method (IBEM), and the effect of cavity interval and spectrum of incident waves on the amplification are studied...
where Δω denotes the small interval around a mean frequency ω¯(Δω/ω¯≪1) for which aω differs appreciably from zero. Let k¯=n(ω¯)ω¯/c be the corresponding wave number. Then (43) may be expressed in the form (44)V(z,t)=A(z,t)e−i(ω¯t−k¯t...

Groundwater and process rainfall are, respectively, expressed by E1 and E2, and the maximum seismic intensity and human factor are, respectively, expressed by F1 and F2. The analytic hierarchy structure of the stability evaluation of the anchorage slope is shown in Fig. 2 below: Figure 2 ...
(such as GIT) • Seismic/oil and gas • Media asset or HIPAA archives • File streaming workflows (such as video surveillance) • Unstructured NAS data (such as home directories) • Big data and data lakes (Hadoop with the NetApp NFS connector) • Virtualized workloads (ONTAP 9.8...
porosity logs and resistivity logs of the 65 wells of the sixth,seventh and eighth interval in the work area,we optimized the logging suites which are suitable for measuring in Longdong region,then we proposed a new parameter named oil discerning index(IOD)to identify reservoir fluid properties,...
The southern Merlinleigh Sub-basin, within the onshore Carnarvon Basin, is a frontier area for petroleum exploration with limited seismic coverage and eight exploration wells, of which only two are deeper than 1000 m. For this study, the... Rp Iasky,Arthur Mory,K Ghori,... 被引量: 25发...
The angular unconformity at the base of the Grant Group forms a distinctive surface evident both at outcrop and in the subsurface on seismic and well logs. Detailed analysis of a 2D seismic dataset, integrated with available well data, suggests a complex suite of processes controlling the ...
