Abstract
A method monitors pumping operations of a vehicle that pumps various fluid treatments down into a well being serviced at a well site. The method records the vehicle's engine speed and the values of one or more fluid-related variables, such as pressure, temperature, flow rate, and pump strokes per minute. The values are recorded as a function of the time of day that the variables and engine speed were sensed. In some embodiments, the recorded values are communicated over a wireless communication link from a remote well site to a central office.

A method of monitoring pumping operations at a well site, wherein the well site includes a well with a string of tubing within a string of casing to define an annulus therebetween, the method comprising:
- driving a vehicle to the well site, wherein the vehicle includes a tank, a pump, and an engine adapted to propel the vehicle;
- determining a well site identifier of the well site;
- pumping a fluid from the tank;
- sensing a variable associated with the fluid;
- determining a time of day that the fluid is being pumped;
- storing on an electrical data storage device a first digital value representative of the well site identifier, a second digital value representative of the variable associated with the fluid, and a third digital value representative of the time of day that the fluid was being pumped, thereby creating a stored data record;
- and
- communicating the stored data record to a remote location relative to the well site.
A method of monitoring pumping operations at a well site, wherein the well site includes a well with a string of tubing within a string of casing to define an annulus therebetween, the method comprising:
- driving a vehicle to the well site, wherein the vehicle includes a tank, a pump, and an engine adapted to propel the vehicle;
- pumping a fluid from the tank into the well;
- forcing the fluid through the annulus;
- sensing a variable associated with the fluid;
- monitoring a speed of the engine;
- and
- plotting as a function time a first value representative of the variable associated with the fluid and a second value representative of the speed of the engine.
A method of monitoring pumping operations at a first well site and at a second well site, wherein the first well site includes a first well with a first string of tubing within a first string of casing to define a first annulus therebetween and the second well site includes a second well with a second string of tubing within a second string of casing to define a second annulus therebetween, the method comprising:
- driving a vehicle to the first well site, wherein the vehicle includes a tank, a pump, and an engine adapted to propel the vehicle;
- determining a first well site identifier of the first well site;
- pumping a fluid from the tank and into the first well;
- sensing a variable associated with the fluid;
- determining a first time of day that the fluid is being pumped into the first well;
- storing on an electrical data storage device a first digital value representative of the first well site identifier, a second digital value representative of the variable associated with the fluid, and a third digital value representative of the first time of day that the fluid was being pumped into the first well, thereby creating a first stored data record;
- driving the vehicle from the first well site to the second well site;
- determining a second well site identifier of the second well site;
- pumping the fluid from the tank and into the second well;
- sensing a variable associated with the fluid;
- determining a second time of day that the fluid is being pumped into the second well;
- storing on the electrical data storage device a fourth digital value representative of the second well site identifier, a fifth digital value representative of the variable associated with the fluid, and a sixth digital value representative of the second time of day that the fluid was being pumped into the second well, thereby creating a second stored data record;
- and
- communicating the first stored data record and the second stored data record to a remote location relative to the first well site and the second well site.
