Characterizing the near surface with VSP and well logs

Soo-Kyung Miong, Robert R. Stewart and Joe Wong

ABSTRACT

Well logs and VSP data were acquired in the Rothney well (05-13-022-03W5), to a depth of 130 m, near Priddis, Alberta to test their feasibility in characterizing subsurface features. According to qualitative and quantitative analysis of well logs, five porous zones were identified and their porosities range from 0.34 to 0.58. The processed VSP corridor stack resolved these porous zones and correlated reasonably with the 1-D synthetic seismogram and other well logs. The quality of various well logs and VSP data provide considerable promise for the technique's use in near-surface characterization.
