... Abstract Seismic imaging in the Gulf of Suez is severely affected by salt plays, strong multiple contamination and raypath distortion etc. Consequently, geophysicists face challenges while interpreting the existing surface seismic and planning new wells, both in time as well as depth domain...

... of the higher frequencies, different frequency bandwidth from surface seismic and lack of direct shear wavefield content. This paper discusses key features of a newly developed downhole seismic source (Z-TracTM) that helps address the challenges stated above. This magnetically clamped source is intended...

... objectives. VSP techniques have obtained partial success in parameter estimation, high precision imaging and reservoir characterization, but obtained dataset is range limited and imaging still need to be improved. In order to broaden the range of survey and expand the advantages of VSP to surface seismic...

... been written about seismic imaging in coal seam gas development over the past few years, yet conventional techniques of surface seismic and vertical seismic profiling have not met the resolution requirements to help in making more informed development decisions. Crosswell seismic is a proven technique...

... Abstract Much has written about seismic interpretation and characterisation of the subsurface and until recently, this topic has focused on the traditional techniques such as surface seismic and vertical seismic profiling (VSP). One critical limitation in combining these with well based...

... was on station ahead of time. The checkshot data agreed well with the predicted model and provided a useful verification of its validity. The recorded waveforms produced an image with higher resolution than the surface seismic below the well path for reservoir delineation. Also, seismic phase and time matching...

... checkshots for pore-pressure constraint and geostopping above a key formation top to set casing. Both the wireline and LWD VIVSP showed minor faults that were not apparent on the 3D surface seismic; these faults explain the unusual kick encountered. This high-resolution image was used to decide the sidetrack...

... a case study relating to the 3D high resolution seismic acquisition currently in progress over the Dukhan Field in Qatar. Presented is how 3D VSP and surface seismic are being simultaneously acquired so as to use the VSP data to enhance the surface seismic project in: processing, interpretation...

One method that is becoming more prevalent, 4C OBC seismic, can benefit from logging formations from surface continuously down to the reservoir. In preparation for the processing and interpretation of a major acquisition of 4C surface seismic run to illuminate...
