As mentioned previously, a stratigraphical attribute like acoustic impedance may indicate rock porosity that is known to be important for good production within a reservoir. The link between these types of seismic attributes to well, completion, and production data is crucial to this characterization. Most plays have both structural and stratigraphical elements that need to be understood properly to characterize a reservoir. Examples include frequency, amplitude, phase, porosity, etc. Physical Attributes (Stratigraphical) вЂ“ Attributes that enhance the lithological properties inherit in seismic data.Examples include dip, azimuth, continuity, etc. Geometrical Attributes (Structural) вЂ“ Attributes that enhance the visibility of the geometrical characteristics within seismic data.Understanding this data reveals key factors that hopefully lead to the success of a play.ДЄ myriad of seismic attributes can be derived from the seismic data (figure 2) but all of these seismic attributes can be broken down into two categories: An illustration showing the importance of using available information in seismic interpretation, such as well data and initial 2D seismic data. This knowledge can influence future seismic survey design and the processing parameters chosen, so that the eventual interpretations are tailored for the target reservoir (figure 1). Understanding vertical resolution limitations of seismic data leads to the identification of which rock properties can be appropriately utilized (Hunt et al, 2012). Well logs can be up-scaled to seismic frequencies as well as synthetically modeled to overcome this resolution disparity. However, there is a large resolution difference between well logs and seismic data.

For instance, if a key play driver were porosity, an acoustic impedance and porosity well crossplot could direct one towards an acoustic impedance inversion if there was a reliable correlation. Well logs are important for geophysical work as we can cross-plot measured and/or derived properties that are achievable through seismic methods and manipulations. Various log curves help identify components of a reservoir such as the stratigraphy, structure, and rock properties inherent in the subsurface (Hunt et al, 2012). One of these ways is to use and analyze log responses from previously drilled wells. As geoscientists, the integration of our conditioned geological and geophysical data in regards to reservoir engineering, drilling, and completions need to be done in a meaningful way. Correct interpretation of these measurements is important to the overall economic success of an Exploration and Production companyвЂ™s endeavors. For any given reservoir or resource play, there are geological and geophysical measurements that impact the exploitation of in-situ hydrocarbons.
