Conventional Full Waveform Inversion (FWI), mostly based on diving-waves, has become a standard velocity model building tool. Using a dataset from the deep water on the Mexican side of the Gulf of Mexico (GoM), we show that FWI can be effective at resolving different ...

This paper presents leanings from the 2015 and 2016 North Sea acquisition season with regards to acquiring data with lots of seismic interference noise.

Kaskida is a large three-way reservoir underneath a complex salt body and truncated by a salt weld. Seismic imaging at the reservoir level is impacted by the inhomogeneous illumination from the complex overburden, which distorts the amplitude of reservoir reflectors and generates lots of ...

2D deconvolution is an attractive approach for short period multiple prediction as it does not require direct recording of the multiple generator and can model multiples relating to more than one multiple generator at a time. One drawback, however, relates to an inherent over ...

Make a technical workflow including rockphysics, post-stack gestatistical inversion, seismic forward research and coal constrained pre-stack geostatistical inversion for the fine reservoir predictiong under coal interbedded. This work flow achieved huge success in the new development wells drilling.

A subsurface volume that can be reliably interpreted in terms of geologically-relevant attributes is a reasonable objective for products from depth inversion workflows. Commonly the field geophysics data available are inherently non-unique and deficient (noise, aliasing, etc.), so an implementation of some type of ...

Standard reflection-based model building for land applications is challenging due to reduced data quality, near-surface heterogeneities, and the low-fold of reflection data at shallow depths. Broadband and large offset data acquisitions have been developed with the aim of investigating full waveform inversion (FWI) as ...

In this paper, we discuss the deblending result of a penta-source marine towed streamer data. The small dithering time renders the cross-talk noise to be semi-coherent in all domains, making this dataset challenging for existing deblending techniques. To tackle this data, we propose a ...

3D elastic modelling was performed to compare two acquisition designs . Blind full processing sequence was applied to ensure unbiased conclusions and final quality. Final quality on stack sections are similar in quality for both flat and highly structured sub-surface. some major advantages of ...
