Geophysical
COLOG is known for more than just “logging a hole.” Our engineers often combine conventional geophysical methods with the newest technological advancements to give our clients concise and complete information.
Years of experience and creative thinking combine to yield superior logging methods. COLOG has nearly four decades of experience in every borehole environment from traditional vertical boreholes to underground horizontal and directional applications. We have performed projects at remote locations and in challenging, adverse weather conditions. There hasn’t been a project yet that COLOG can’t design a scope of services to yield valuable and cost-effective data to meet a specific goal or subsurface question.
