Wellbore Navigation, Inc. (Welnav) was formed in 1981 expressly to design and manufacture a new-improved family of Directional Survey Instrumentation and Software. Welnav's key personnel had been employed by all the major survey instrument manufacturers before forming Welnav.

    Uniquely, Welnav planned to operate as a Directional Survey Service Company and to sell the products to companies and countries who wished to enter the directional survey market.

    Welnav manufactures a complete line of Photographic and Electronic Magnetic and Gyroscopic Survey tools.

    To date, Welnav is the only company who manufactures a survey product line and sells the products as well as uses them in a competitive Directional Survey Operation.

    Some companies manufacture survey instruments for their own use. They do not sell!!

    Other companies manufacture survey instruments, for sale only. They do not operate a field service!! Therefore, they lack the necessary field experience to design competitive survey systems.

WELNAV SELLS WHAT WELNAV USES!!!!

    Of utmost importance is the need for accurate, well presented computer software to meet the customer's needs.

WELNAV'S COPYRIGHTED SOFTWARE SATISFIES THESE NEEDS!!!

    Welnav designs the total software package to insure the survey data is presented in a state of the art manner. If necessary, software changes can be made to accommodate specific customer needs.

WELNAV WROTE THE SOFTWARE, SO WELNAV CAN CHANGE THE SOFTWARE!!!!
