WebThe benefits provided by broadband seismic can be demonstrated by means of some modeling and then with case studies in various geological settings: from frontier to more mature areas without well control and with much reduced well control. The 2D wedge-model shown in Figure 1 provides more insight into the benefits of broadband seismic data. WebThe wedge model runs from 80 feet to zero thickness with the associated densities and velocities indicated in Figure 1. Displayed below the wedge model is an amplitude display with an Ormsby 5-10-60-90 wavelet applied. grilled chicken orzo saladWebthermal structure of the wedge depends upon a number of dynamic and rheological factors [Kincaid and Sacks, 1997]. Seismic attenuation (described by a quality factor, Q) provides one tool for imaging temperature. At mantle conditions the attenuation of seismic waves occurs through a variety of temperature-dependent grain-scale processes fifo jobs for women western australia
