By perforating the casing both below and above the packer, as shown in figure 2-1, a lease operator can produce natural gas from two different…
“Mendoza, this meter is broken”, I complained. “Every time we increase the compressors speed to pull-down the wellhead pressure, the recorded gas flow drops. I…
One of the more puzzling phenomenon I have observed in gas field production happened during my tenure as an operator of wellhead compressors. One would…
Rapidly opening the wellhead valves on a high pressure well flowing into a low pressure collection system is a good way to ruin a well…
Equation 5 implies that the lower the density of the liquid accumulating in the tubing, the lower the entrainment velocity. This means that less gas…
The valve trim on the intermitter should be at least twice the diameter of the choke. When the intermitter valve opens it should not restrict…
Mr. Howlaway eyed my equations suspiciously, “I can see that you have developed a method to predict the combination of the gas production rate and…
When I first started troubleshooting partially depleted natural gas wells, I often wondered why so many of the hundred odd wells I visited were averaging…
A well that produces 100,000 SCFD of gas as a minimum, but periodically reaches a peak production rate of 300,000 SCFD once a day, is…
Although we have been talking about wellhead pressure (both shut-in and flowing tube), the wellhead pressure is just an indirect indication of the really important…
