چکیده مقاله:

The field of rock physics represents the link between qualitative geologic parameters and quantitative geophysical measurements. Increasingly over the last decade, rock physics has become an integral part of quantitative seismic interpretation and stands out as a key technology in petroleum geophysics. Ultimately, the application of rock physics tools can reduce exploration risk and improve reservoir forecasting in the petroleum industry. This paper covers basic rock physics principles and practical recipes that can be applied in the field. The importance and benefit of linking rock physics to geological processes, including depositional and compactional trends, is demonstrated. It is further documented that lithology substitution can be of equal importance to fluid substitution during seismic reservoir prediction. It is essential in exploration and appraisal to be able to extrapolate away from existing wells, taking into account how the depositional environment changes, together with burial depth trends. In this way rock physics can better constrain the geophysical inversion and classification problem in underexplored marginal fields, surrounding satellite areas, or in new frontiers. A methodology is presented where rock physics models are used to screen for reservoir sandstones and hydrocarbon pore-fill from seismic inversion data. Most seismic attributes are based on empirical relationships between reservoir properties and seismic observables. In this study, we honor the physical properties of the rocks by defining attributes that comply with calibrated rock physics models. The attributes include the fluid impedance (CPEI) and the rock impedance (PEIL). We demonstrate the use of these attributes on well log and seismic inversion data from the Norwegian Sea, and successfully screen out reservoir rocks filled with hydrocarbons.
