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 ...

In offshore prospective areas, oil slicks at the sea surface are often seen as being the visible expression of a working petroleum system at depth. Synthetic Aperture Radar (SAR) has proven to be an effective tool for identifying these oil slicks by virtue of ...

This paper presents recent advances in the area of seismic interference (SI) attenuation. We show how high amplitude and broadside SI noise can be nearly perfectly attenuated as long as the interfering noise is shot-to-shot incoherent. Furthermore, we present a new algorithm that also ...

In this paper we present a new marine seismic acquisition technique initially developed to meet imaging challenges of the Loppa High in the Norwegian Barents Sea. Two seismic vessels operate in tandem; one streamer vessel towing a spread of deep, densely spaced streamers, and ...

Survey design comparison regarding seismic reservoir characterization objectives: a case study from South Tunisia L. Michou, L. Michel, P. Herrmann, T. Coleou, P.Feugere, J.L. Formento The objective of this onshore survey designs’ comparison case study is to highlight the impact of the acquisition trace ...
