Multicomponent seismic recording (4C) is becoming more common in several offshore seismic applications. Faithfully recording all Cartesian components of seafloor particle motion is essential in the ultimate application of new 4C methods. In addition to 'perfecting' the acquisition and processing technology, however, we must ensure that the end users and interpreters gain a complete understanding of just how to use the new technology in a practical and expedient manner. This will require both the education of the end user and the development of truly predictive interpretive models by the technology developers for each new technology application.Multicomponent recorded is essential if we are to incorporate seismic shear-wave data into interpretations. Since shear waves do not propagate in fluids, including sea water, recording them requires sea bottom instrumentation that is coupled to the sea bottom and can faithfully record the full vector seismic response. Since seismic shear waves and the more conventionally applied P-waves respond differently to solids and fluids, simultaneous interpretation of two types of data can significantly improve our estimates of subsurface reservoir and fluid properties.Actual applications of multicomponent seismic methods include imaging through the distortions caused by shallow gas, direct detection (and estimation) of hydrocarbons (gas), estimation and discrimination of lithology and detection of reservoir sands that have a poor response to conventional seismic reflection methods. All of these techniques have been accepted-to varying degrees-by the und users of seismic methods. All are applicable in both the land and offshore environments and thus case histories of land examples may be used to evaluate their potential to offshore applications.Observations of seismic anisotropy have been made in land shear-wave data and applied to estimation of fracture parameters (orientation and intensity). Such applications have exploited the controlled polarization of the shear-wave seismic source, which is not available in the offshore environment. Research is currently progressing to address extension of these particular applications to the offshore setting.

“…and later Macrides and Kelamis (2000) estimated Vp/Vs ratios for lithology discrimination, estimated from time-thickness data. They proposed average Vp/Vs ratios of 1.6 for clean sandstones, 2.0 for limestones and 2.4 for silty or shaly sands.…”

The monitoring of a SAGD heavy oil reservoir is commonly executed through time-lapse 3D seismic surveying, focused on identifying areas of steam stimulation by tracking the movement of a steam front, and identifying areas of bypassed reserves. In this thesis, we processed and interpreted a 4D -3C seismic dataset, identified time-lapse amplitude anomalies and isochron time-delays associated with the injection of high volumes of steam into a McMurray Formation reservoir. Through processing, and the application of a novel calibration procedure, non-production related differences between the baseline and monitor seismic surveys were minimized. Production-related differences were analyzed through a variety of geophysical techniques, and were projected into a map display to delineate the spatial position of the reservoir steam zones. It was interpreted that the observed amplitude anomalies corresponded to steam injection, while concurrent time-delays represent reservoir heating above pre-injection ambient temperatures.

“…The seismic source may contribute to the data boom as well. On land, shear vibrators can be added to the conventional vertical ones, accumulating up to 9‐component data sets (Macrides and Kelamis 2000). Although such surveys are uncommon, the related technology has been validated and commercially available for years.…”

A B S T R A C TSeismic tomography has been developed and applied for decades in seismological applications and for basic research purposes. During the last decade, large-scale applications in the oil and gas industry became standard as tomostatics and velocity modelling for pre-stack depth migration. In this paper, I take a snapshot of some current industrial applications, quantifying practical aspects by yardsticks such as data and model size and I try to draw a road map for the current decade.
