Wide Line Seismic Acquisition Technique in a Hilly Terrain of Onshore Myanmar

Abstract

Myanmar's onshore block EP-2 is a small exploration concession with high potential structures located on the eastern side of the Irrawaddy River. One of the major anticlinal structures can be mapped based on surface geological survey, but the recent 2D seismic data has extremely poor quality due to a severe static and strong side scattered noise. Although the size of this prospect is attractive, the subsurface uncertainties are considered too risky for further drilling operation. An alternative acquisition technique called "2D-wide line" was firstly implemented in Myanmar. Its results provide better stack sections, more reliable velocity function and higher geological probability of success.
