Abstract

As part of a permanent down-hole seismic system project, a wireline multi-offset, vertical seismic profile (VSP) was acquired in a well at Halliburton’s Carrolton, Dallas, Texas, test facility. A vibratory source was used to acquire four offset VSP profiles, one walk-away (five-source positions) and a zero-offset VSP. The zero-offset VSP was also acquired with an air-gun source. The down hole threecomponent receiver arrangement consisted of a wireline multi-station tool with eight levels at 50-ft separation and with a hydraulic clamping system. The tool was run up from 2900 to 1000 feet using the vibrator and from 2050 to 900 feet using the air-gun source.
