Abstract Borehole measurement systems are used for measuring parameters in borehole exploration facilities. Measuring methods include the use of various sophisticated tools that are descended into boreholes. Various parameters are monitored in order to avoid damaging expensive equipment. These parameters include tool velocity, depth, cable tension, MMD - magnetic marker detector, CCL- casing collar locator and differential tension. During logging in horizontal wells critical parameters must be displayed to the drilling operator. This paper presents a hardware realization of devices for monitoring critical well logging parameters, which satisfies the requirements for monitoring and displaying these parameters on the borehole site.
