System and method for positioning equipment for well logging

Abstract

A system and method for positioning equipment on a track system where the equipment may descend a wireline or a cable into a borehole for well logging. The equipment may be a drum unit for storing, deploying and retracting the cable, a winch, a dancer unit and an auxiliary power supply. The equipment may be positioned with the track system for either operations or transport. The cable may be threaded through the equipment to descend into the borehole for well logging purposes.

We claim: 
     
         1 . A method for positioning equipment on a platform for placement on a vehicle, comprising:
 placing a track system on the platform to move the equipment;   mounting the equipment on the track system wherein the equipment enables deployment of the cable; and   moving the equipment on the track system to a position to descend a cable through a borehole.   
     
     
         2 . The method of  claim 1 , comprising:
 securing a drum unit on a winch frame.   
     
     
         3 . The method of  claim 1 , comprising:
 adhering a gripping block onto a winch to abut against the cable.   
     
     
         4 . The method of  claim 1 , comprising:
 deploying the cable through a dancer unit to control a tension in the cable.   
     
     
         5 . The method of  claim 1 , comprising:
 powering the track system with a hydraulic power supply.   
     
     
         6 . The method of  claim 1 , comprising:
 controlling the equipment from an electronic control module.   
     
     
         7 . A method for deploying a cable into a borehole, comprising:
 situating equipment on the track system to deploy the cable into the borehole;   threading the cable through the equipment;   sending a signal from an electronic control module to control the equipment; and   descending the cable wherein the cable travels through the equipment into the borehole to obtain well logging data.   
     
     
         8 . The method of  claim 7 , comprising:
 reducing an increase in a tension in the cable through a compression of a shock absorber on a dancer unit.   
     
     
         9 . The method of  claim 7 , comprising:
 preventing slippage of the cable by mounting a gripping block on a winch to abut against the cable.   
     
     
         10 . The method of  claim 7 , comprising:
 deploying the cable from a dancer unit in response to an increase in tension in the cable.   
     
     
         11 . The method of  claim 7 , comprising:
 maneuvering the cable through a driven sheave in a dancer unit.   
     
     
         12 . The method of  claim 7 , comprising:
 measuring footage of the cable.   
     
     
         13 . The method of  claim 7 , comprising:
 measuring tension in the cable on a driven sheave.   
     
     
         14 . The method of  claim 7 , comprising:
 monitoring equipment performance during cable deployment.   
     
     
         15 . A system for positioning equipment on a track system mounted on a platform, comprising:
 a drum unit;   a winch;   a dancer unit that deploys cable to control an increase in a tension in the cable;   a cable threaded through the drum unit, the winch, and the dancer unit to descend into a borehole; and   a power supply that provides power to the equipment.   
     
     
         16 . The system of  claim 15 , wherein the cable being encapsulated by a carbon fiber polymer jacket. 
     
     
         17 . The system of  claim 15 , wherein the drum unit maneuvers the cable. 
     
     
         18 . The system of  claim 15 , wherein the winch rotates to pull the cable from the drum unit. 
     
     
         19 . The system of  claim 15 , comprising:
 a shock absorber on the dancer unit that compresses to reduce tension in the cable.   
     
     
         20 . The system of  claim 15 , comprising:
 an electronic control module that sends a signal to control the drum unit, the winch and the dancer unit.
