Wellbore surveying is all we do, and we wake up each morning asking ourselves how we can be an even better survey provider to our customers, with extraordinary customer service, more innovative technology, stronger local presence, and faster and more accurate final results. As the largest independent wellbore surveyor in the United States, with a growing international presence, we are ready to work alongside our customers and committed to always recommending what’s best for them.

We are there for our customers, to do every job—from the most challenging to the most routine—accurately, when they want it, and how they want it. We never stop until our customers are satisfied.


We measure our success by how much we can help to maximize our customers’ drilling efficiency. Through a combination of our local presence, a broad array of fast, pre-calibrated, and field-friendly survey technologies, and the experience of our survey engineers, we seek to get our customers the quickest survey results with the least amount of disruption to their drilling operations.

Our People

Wellbore surveying is our sole focus and our passion. Our team of dedicated survey engineers brings years of experience in delivering extraordinary personal service and working with our R&D centers to jointly develop customer-focused surveying technology.


We start by recruiting skilled field engineers and a corporate and technology team dedicated to exceeding customer expectations.


Our survey engineers are trained in-house with processes to ensure speed, reliability, and quality in every survey.

Our Capabilities

We are wellbore survey specialists, dedicated to providing complete, flexible, fast, and highly accurate survey services. Our surveying engineers can work in every mode:

VES wireline

We conduct many surveys using our own fleet of new model, impeccably maintained, highly reliable wireline trucks. We also work on third-party wireline.

Drop and memory modes

Our survey engineers can also run tools in free fall drop mode and memory modes using slickline.

Gyro steering services

With robust solid state sensor technology, we are now able to provide seated gyro while drilling services for orientation and kick off applications, where MWD cannot be used.

Other services

With our own fleet of wireline trucks and our highly skilled survey engineers, VES offers wellbore temperature and gamma logging services alongside our core innovative wellbore surveying services.
