Schlumberger has acquired five VSP surveys on behalf of EnCana in Alberta. The primary goal of the VSP surveys is to study the azimuthal variations in the AVO response of the coals of the Mannville Formation. The zero-offset VSP survey was processed using vista through to corridor stack and shows high reflection quality.
