Portable memory device for mobile workover rig

Abstract

This invention provides a self-contained mobile repair unit having a universal set of hydraulic and pneumatic tooling for servicing well equipment such as an inner pipe string, a sucker rod, or a pump. One or more transducers sense and collect data indicative of one or more parameters measured by the mobile repair unit, such as hook load, engine RPM, or tongue torque. The data is collected and saved in a non-volatile memory device, which is then physically transferred from the mobile repair unit to a central office location, where the data can be compiled, analyzed, and/or posted on a network such as the Internet.

I claim:  
     
         1 . A system for monitoring operations at a well, comprising: 
 a mobile vehicle containing a data acquisition monitor and at least one tool for monitoring an operation of the well;    at least one transducer associated with each tool for providing a parameter indicative of the operation of the well, wherein each transducer provides an electronic signal to the data acquisition monitor;    a hand-held non-volatile memory device coupled to the data acquisition monitor, wherein the memory device is physically removable from the data acquisition monitor for relocation to a predetermined location.    
     
     
         2 . The system of  claim 1 , wherein the mobile vehicle further comprising a truck frame supported on a plurality of wheels.  
     
     
         3 . The system of  claim 2 , further comprising an engine selectively coupled the wheels.  
     
     
         4 . The system of  claim 3 , wherein the engine is selectively coupled to a hoist.  
     
     
         5 . The system of  claim 3 , wherein the engine drives a hydraulic pump.  
     
     
         6 . The system of  claim 5 , wherein the hydraulic pump powers a set of hydraulic tongs for use in the instillation and removal of pipe segments within the well.  
     
     
         7 . The system of  claim 5 , wherein the hydraulic pump powers a plurality of hydraulic cylinders for moving a derrick attached to the mobile repair unit.  
     
     
         8 . The system of  claim 1 , wherein the parameter is selected from the group consisting of a hydrogen sulfide gas concentration, hook load, engine RPM, and tong torque.  
     
     
         9 . The system of  claim 1 , wherein the electric signal is selected from the group consisting of analog and digital signals.
