Shallow Waterflow Detection Using Prestack Inversion

N-37 SHALLOW WATERFLOW DETECTION USING PRESTACK INVERSION Summary Highly porous sands prone to flowing when drilled (shallow waterflow sands) pose a serious risk and have cost the oil industry hundreds of millions of dollars to date. Detection of these shallow waterflow prone sands is important for reducing environmental risks and commercial losses. The use of standard seismic data for detection has been explored and found successful at the Ursa site in the Mississippi Canyon area of the Gulf of Mexico. Although the data quality of the selected set is at or below average reprocessing at 2 ms yielded sufficient quality
