... be used for azimuthal imaging. The results of the study shows that extra information extracted from the azimuthal imaging may reduce the exploration risks without acquiring a new seismic data over the prospective area. The main motivation of applying Common Reflection Angle Migration (CRAM) to 3D seismic...

... after starting PANGEA, CPU time for a WATS Reverse-Time-Migration (RTM) in a deep offshore field in Angola was reduced from one month to 54hr, and a Kirchhoff PSDM in Gabon pre-salt prospect ran in 3.5hr instead of 48hr before. Such time-saving power also allows running processes at levels thought...

.... The historical exploration drilling success rate is approximately 40%; the main exploration risk elements for a given prospect on the block are reservoir and trap geometry. Source and hydrocarbon migration risk are low. The challenge in Block 0 is to make a step change improvement in seismic data quality...

... and history of the basins. Alteration of oils occurs by the dominant scheme. The system of hydrocarbon solutions is a synergy system. It is suggested that the top horizons accumulate a total geochemical "memory based on the character of hydrocarbon migration. Using a technique of petroleum component balance...

... in an exploration phase it is important to develop 3D basin modeling tools that can utilize these data in a cost effective way. INTRODUCTION The term "Basin Modeling" is today mostly associated with the simulation of the thermal history of a basin, the generation and expulsion of hydrocarbons and the migration...

... work were to establish the causes of the CVE and to investigate methods to reduce or eliminate its effects. As a first step, a review of all available laboratory and field data was undertaken to identify the most likely causes of the CVE. It was hypothesized that reservoir fines migration was the most...

... the depositional, thermal, and fluid flow history of an evolving sedimentary basin. The basin-scale simulator can model multi-phase, multi-component, fluid flow, including hydrocarbon generation, expulsion and migration. The 3D input data sets can be tedious to construct. Output data sets are unwieldy...

.... Mini- misation with respect to the intercept and slope leads to two five-fold integral equations. Application of multi-dimensional stationary phase approximation reduces these integral equations to manageable algebraic form. The final algorithm amounts to performing two localised migrations, one...

The increased use of 3D seismic data in exploration is a trend that will continue and bring with it opportunities to use new geophysical developments in prestack depth migration, amplitude versus offset lithology...

... Abstract. The Probases system of 2-D basin simulation and evaluation is a multi-functional and integrated system in basin simulation. Its process for modelling couples the basinal processes including fault growth, sedimentary compaction, fluid flow, hydrocarbon generation and migration...

... with the increase in computational power has spurred the recent developments of economical prestack depth migration algorithms. Central to the success of any depth imaging technology is the construction of quality velocity models. Advances in velocity estimation techniques, improved data base interfaces...
