Shooting direction and crosswell seismic data acquisition

At the Glenn Pool field in Northeastern Oklahoma, a series of crosswell seismic surveys have been acquired. The acquisition parameters and shooting geometry were careful developed using a test survey. The first full survey resulted in high quality data, but the second encountered high ambient noise. The noise levels were high enough to prohibit first-arrival picking over in much of the data. Analysis of the data from the second survey shows that tube waves are emanating from the perforated interval in the receiver well. This is interpreted to be fluid flow or circulation noise through the perforations, even though the well was not flowing fluid at the surface. Since this image plane was important for characterization of the reservoir, the survey was re-shot by reversing sources and receivers in the two wells. The resulting high-quality data indicates that shooting direction can be an important acquisition factor.
