Deblending shallow water OBC data can be challenging. High blending fold, strong early arrivals, shear wave energy, and background noise all add to the complexity of the problem. Using an offshore Trinidad OBC survey, including dual and triple sources, we demonstrate the effectiveness of ...

The oil-bearing fractured granite basement rocks form a very important and complicated hydrocarbon reservoir in Cuu Long basin offshore Vietnam. However, the poor fractured basement imaging in the conventional tow streamer data makes it hard for detailed interpretation and future well placement. To improve ...

The Wolfcamp reservoir of the Permian Basin has recently generated interest for its potentially vast oil and gas reserves. Imaging this reservoir using seismic data is challenging despite the uncomplicated geology at reservoir depth, because the near-surface in this region is complex. In this ...

Complex overburdens often distort reservoir images in terms of structural positioning, stratigraphic resolution, and amplitude fidelity. One prime example of a complex overburden is in the deepwater Gulf of Mexico, where thick and irregular layers of remobilized (i.e., allochthonous) salt are situated above prospective ...

This study is based on work performed on horizontal wells in the Cleveland Sandstone Formation. Previous work describes the technique of using automated, quantitative mineralogy (RoqScan) to analyse drill cuttings and derive rock property and elastic pseudo-logs to customize completion designs. We expand on ...

Deterministic seismic inversion methods have been successfully used in many exploration and production projects in the petroleum industry. Some of the benefits of these methods are: the inverted impedances are rock properties tightly calibrated with well data; the seismic inversion process itself attenuates the ...

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 ...
