In prior posts (see: What Oil Producers can learn from the Oklahoma Cowboy’s football stadium), we demonstrated how heat from the sun (ie “heat transfer”) is the single largest modifier of measured oil sales.

Essentially, when selling oil, the number of barrels is computed, then the temperature correction factor is applied…

Now, if the oil is cold, this factor will increase the number of barrels shown as sold. And, if the oil temperature is above the temperature at the quoted price, the number of barrels computed as sold will be reduced.

So, how do we get an accurate reading of the temperature of the tank’s contents?

Enter the gauger’s Scoop Master tank thermometer

The Scoop Master tank thermometer is an accurately computed device that contains a holding pocket to reduce temperature changes while it is being read. The thermometer is attached to the gauger’s tray by a cord which allows it to be lowered into the middle of the tank of oil to obtain the temperature of the tank’s contents…

Besides the sun, can you think of any other sources of “heat” at the well site?

Let’s direct our attention toward the burner in the heater-treater…

Heater/treaters are used extensively to heat and treat crude oil. Heat is applied to the crude oil by both the sun and by burners in heater/treaters.

Every so often, operators make the mistake of installing their tank’s hatch near the inlet where heated oil enters the tank after being processed by the heater-treater.

When the purchaser drops his thermometer through the hatch, the close proximity to the inlet line causes the thermometer to read at much higher temperatures than the actual average temperature of the oil in the tank.

For example, if a thermometer records a temperature of 125 degrees (but the average temperature of the oil is closer to 100 degrees), the seller will lose 12 barrels out of every 1000 barrels sold.

There may have been a day when warming up the thermometer on a light bulb worked to convince your mother or the school nurse of just how sick you really were…

But today, the joke may be on you!

Potential Savings: 12 barrels of every 1000 barrels produced.
