... changes such as depositional break, parallel unconformity and coal beds. In this paper, a case of suppression for interbed mutilples caused by coal beds in Junggar basin was presented. The extended SRME method was used to predict the interbed multiple models and then the multiples were subtracted from...

... ABSTRACT Coal is one of the important resource rocks in Malay Basin. It dominants from Group E to Group I which are the main hydrocarbon reservoirs in Malay Basin. A coal bed is a good indicator in structural interpretation, however the existence of coal interferes the interpretation...

... of the stratum of one basin south china. There are several faults, fractures and collapse columns in this physical model, but this paper just focuses on the shielding effect of coal seams on seismic imaging underlying layers which can cause the of the reflection events beneath the coal beds. The design...

... Summary In highly cyclic sedimentation with large impedance contrasts, such as coal beds, peg-leg multiples make seismic ties with primary-only synthetics difficult (Qi and Hilterman, 2013b). A processing technique based on time-varying matched filters is presented for removing the effects...

... convolution replicates the effects of interbed multiples in the output trace. These include significant time delays of the primary energy (Stewart et al., 1984) and high frequency loss for the transmitted wavelets for highly cyclic sequences such as coal beds (O’Doherty and Anstey, 1971). Because each column...

... Summary Due to coal beds existing in the middle of higher velocity wall rocks, seismic wave interferencing with each other generates guide wave propagating within coal beds and surrounding wall rocks (Liu,1994). Three dimensional channel wave propagating within homogeneous isotropic...

... Summary Methods of measuring seismic azimuthal anisotropy are being used increasingly to detect fractures in reservoirs. Coal beds contain cleats, which are fractures in the coal that allow fluids, particularly methane, to flow through this type of reservoir. This suggests that estimates...
