Seismic Data Acquisition and Previous HitProcessingNext Hit in the Midway-Sunset Oil Field

C. R. Willingham, A. S. Wylie Jr., D. J. Underwood


In 1991 and 1993 two seismic surveys were acquired across and in the vicinity of the Midway-Sunset Oil Field. High Previous HitqualityNext Hit imaging has been difficult to obtain due to noise from the thousands of pumping wells, and steamflood operations associated with the field. Complex subsurface structure has also contributed to the problem.

This paper discusses the acquisition and Previous HitprocessingNext Hit history of these surveys and the numerous methods applied to analyze and to reduce the effects of “production” noise. Also, discussed is the application of a mini-3D Previous HitprocessingNext Hit technique on one test line. This technique has provided results indicating that imaging Previous HitqualityNext Hit of a 3D survey may be substantially su- perior to that of comparable 2D data.
