Abstract The ray series method may be generalized using a ray centered coordinate system for general 3D-heterogeneous media. This method is useful for Amplitude Versus Offset (AVO) seismic modeling, seismic analysis, interpretational purposes, and comparison with seismic field observations.For each central ray (constant ray parameter), the kinematic (the eikonal) and dynamic ray tracing system ...
Vve examine seismic waves scattered from anisotropic heterogeneity with laboratory data and numerical modeling in order to develop modeling techniques for the characterization of fracture p'roperties in tight gas sands from surface seismic reflection data. Laboratory models representing features of a fractured reservoir were constructed using Phenolite (the "reservoir") embedded in a Lucite bac...
In our last SEP report, we introduced an AVO dataset consisting of seismic, petrophysical and well-log information which was provided by Mobil as part of an AVO workshop (?). The prestack seismic data are heavily contaminated by free-surface and water-bottom multiple reflections, and thus represent a challenge for true-amplitude processing. We described our preliminary preprocessing work and di...
The presence of gas hydrate and associated gas in the Makran Accretionary Prism, offshore Iran, has been confirmed by various seismic indicators, including the bottom-simulating reflector (BSR), amplitude blanking, and bright spot. The pre-stack analysis and the study of amplitude-variation-with-offset (AVO) attributes are the most reliable tools for semi-quantitative study of gas hydrate and f...
In this article we investigate AVO effects of large offset P-wave data (up to ) and converted waves (up to ). In addition to conventional P-wave AVO attributes ( and ) a third term ( ) is examined. For P to S converted waves we introduce two AVO attributes and . Background trends for certain cross plots are related to rock property relationships. These new attributes are used to discriminate co...
تحلیل AVO امروزه روشی معتبر و مفید برای تشخیص هیدورکربن‌‌ها است. با استفاده از ارتباط دامنه در برابر دورافت و روابط زوپریتس و تقریب‌های آن می‌‌توان نشانگرهای متفاوتی استخراج کرد تا به کمک آنها محدوده‌‌‌های مخزنی از لحاظ شاره و سنگ‌‌شناسی تفکیک شود. در این مقاله تحلیل AVO روی مخزن ماسه‌سنگی غار در میدان ابوذر واقع در خلیج فارس صورت گرفته است. با کمک روش‌‌‌های تحلیل AVO شامل مدل‌سازی مستقیم، م...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
We are developing a large-scale model of language comprehension in ACT-R 6 for use in the creation of a synthetic teammate that can function as the Air Vehicle Operator (AVO) in a three-person simulation of an Unmanned Aerial Vehicle (UAV) team performing a reconnaissance mission. The use of ACT-R 6 to implement the core components of this system reflects the strong cognitive modeling orientati...
