Oil well servicing system
First Claim
1. A well servicing system for a plurality of well sites being serviced by a service vehicle that is adapted to perform a first service operation at a first well site of said plurality of well sites and perform a second service operation at a second well site of said plurality of well sites, said first service operation and said second service operation being measurable by monitoring a parameter that varies in response to at least one of said first service operation and said second service operation being performed, said well servicing system comprising:
- a transducer adapted to be kept resident with said service vehicle even as said service vehicle becomes relocated between said first well site and said second well site, said transducer being adapted to sense said parameter at said first well site and provide a first analog feedback signal that varies as a function of said parameter at said first well site, said transducer being adapted to sense said parameter at said second well site and provide a second analog feedback signal that varies as a function of said parameter at said second well site;
an analog to digital converter adapted to convert said first analog feedback signal and said second analog signal to a first digital feedback signal and a second digital signal respectively;
a first well site identifier at said first well site and being associated with a first digital well site value;
a second well site identifier at said second well site and being associated with a second digital well site value that is distinguishable from said first digital well site value;
a memory being adapted to store said first digital feedback signal and said first digital well site value in reference to each other and being adapted to store said second digital feedback signal and said second digital well site value in reference to each other; and
a communication link that communicates at least one of said first digital feedback signal, said second digital feedback signal, said first digital well site value and said second digital well site to said memory, whereby said first service operation performed at said first well site can be distinguished from said second service operation performed at said second well site.

Abstract
A well servicing system includes a vehicle that travels to perform a service operation at several well sites while monitoring and recording data that reflects the performance of the operation at each site, and then associates that data with unique well site identifiers. The information is stored and secured against tampering to provide a reliable record of what work was done at each particular well site.

19. A well servicing system for a plurality of well sites being serviced by a service vehicle that is adapted to perform a first service operation at a first well site of said plurality of well sites and perform a second service operation at a second well site of said plurality of well sites, said first service operation and said second service operation being measurable by monitoring a parameter that varies in response to at least one of said first service operation and said second service operation being performed, said well servicing system comprising:
-
a transducer adapted to be kept resident with said service vehicle even as said service vehicle becomes relocated between said first well site and said second well site, said transducer being adapted to sense said parameter at said first well site and provide a first analog feedback signal that varies as a function of said parameter at said first well site, said transducer being adapted to sense said parameter at said second well site and provide a second analog feedback signal that varies as a function of said parameter at said second well site, said parameter being at least one of a pressure, a temperature, a force, a rotational speed, and a rate of flow;
an analog to digital converter adapted to convert said first analog feedback signal and said second analog signal to a first digital feedback signal and a second digital signal respectively;
a first well site identifier at said first well site and being associated with a first digital well site value, said first well site identifier including at least one of a first bar code and a first electromagnetic element;
a second well site identifier at said second well site and being associated with a second digital well site value that is distinguishable from said first digital well site value, said second well site identifier including at least one of a second bar code and a second electromagnetic element;
a memory being adapted to store said first digital feedback signal and said first digital well site value in reference to each other and being adapted to store said second digital feedback signal and said second digital well site value in reference to each other; and
a communication link that includes at least one of a bar code scanner and an electromagnetic detector, said communication link communicating at least one of said first digital feedback signal, said second digital feedback signal, said first digital well site value and said second digital well site to said memory, whereby said first service operation performed at said first well site can be distinguished from said second service operation performed at said second well site. - View Dependent Claims (20)
