| Summary: | Amplitude Variation with Offset (AVO) is a technique that has been widely used as an <br />
<br />
<br />
<br />
<br />
indicator of the presence of hydrocarbons in seismic data. This technique mathematically <br />
<br />
<br />
<br />
<br />
uses an approach to the Zoeppritz equation to identify changes in amplitude as a function of <br />
<br />
<br />
<br />
<br />
the incident angle and relate it to the rock properties and fluid content. In this study, a new <br />
<br />
<br />
<br />
<br />
attribute, Energy-weighted AVO, was used to identify the presence of hydrocarbons in the <br />
<br />
<br />
<br />
<br />
Penobscot field, Canada. The main principle of this attribute is to improve the anomaly <br />
<br />
<br />
<br />
<br />
response associated with hydrocarbons as well as to attenuate the background seismic <br />
<br />
<br />
<br />
<br />
around the anomaly. The advantage of this attribute is to distinguish the hydrocarbon <br />
<br />
<br />
<br />
<br />
anomaly response to other anomalies caused by lithology such as coal. In addition, this <br />
<br />
<br />
<br />
<br />
attribute is applicable to both pre-stack and post-stack seismic data. |
