oa Listening to the Right Thing: The Integration of Low Frequency Seismic Data with Other Geophysical Methods as a Frontier Exploration Tool in the South Rub ‘Al Khali Basin

The South Rub ‘al Khali Company Ltd is an Incorporated Joint Venture between Shell Saudi Ventures<br>Limited (50%) and Saudi Arabian Oil Company (50%) and was set up in order to explore for nonassociated<br>gas in the South Rub ‘al Khali Basin as part of the Natural Gas Initiative in the Kingdom of<br>Saudi Arabia.<br>Following an initial three well exploration drilling campaign in SRAK’s Contract Area 2 (CA2), SRAK<br>embarked on a second major phase of 2D seismic acquisition. Low frequency seismic data has been<br>acquired on all new 2D seismic lines via an embedded recording set-up. This has resulted in the largest<br>combined PSTM / LF exploration data sets acquired to date.<br>One of the key challenges facing low frequency seismic as an effective exploration tool is the lack of<br>signal depth discrimination. This presentation will focus on the combination of low frequency seismic<br>with conventional seismic products in order to constrain the depth of the low frequency signal and how<br>combining these workflows with geologic models has led to the identification of a potentially new<br>hydrocarbon play in the southern Rub ‘al Khali Basin.
