This paper presents a detailed case history of the evolution of fracture technology in the Hanoi Trough, Vietnam. The target formations are stacked fluvial channel deposits that occur at depths of 10,000 to 12,000 ft with permeability ranging from to 1 mD. The first three wells drilled in 1996-97 were fracture stimulated, but only one of the three treatments was successful. Three more wells were drilled in 1999 and significant improvements in completion and hydraulic fracture technology were implemented. This paper presents a comprehensive data set, which includes the evaluation and integration of pre-& post-fracture well tests and log data with detailed fracture modeling analyses to understand and improve fracture performance in this complex environment.
