Piezoelectric Vertical Seismic Profile Tool (PiezoVSP) Job

October 2015, first Piezoelectric type Vertical VSP (PiezoVSP) job (one Zero-offset source and one offset-VSP source) had been finished successfully in Xinjiang, China.

PiezoVSP got satisfied data in both casing and openhole interval. No arms and 48 mm O.D. design reduces operation risk and improve efficiency.

PiezoVSP is especially used for hostile environment. It can also through pipe, even though special bit, may instead of Seismic While Drilling (SWD) sometime.
