To further complicate the adjustment of a field compressor, one needs to be aware of certain transient effects that the well imposed on the compressor.…
If a compressor has an excessively high second-stage (crankend) discharge temperature and a low first-stage (head-end) discharge temperature, one should proceed as follows: • Reduce…
As the wellhead pressure falls, the differential pressure that the field compressor must deliver increases. This is because the collection header into which the compressor…
There are three fundamental limits to which all field compressors are subject: • Compressor rod loading • Speed • Engine horsepower In addition to calculating…
The easiest, but least cost effective method, to operate a field compressor is the crank-end mode. When only the Crank-end (i.e. second stage) is in…
This incident illustrates the importance of adjusting field compressor operation to maintain a minimum velocity in the production tubing. The velocity must be sufficient to…
Figure 4-1 illustrates a typical two-stage compressor. Machines of this type range from 30 to 300 horsepower. They are driven by a gas engine; fueled…
For each barrel of natural gasoline condensate collected in storage, roughly 1,300,000 BTU’s worth of gas is flashed-off from the low pressure three phase separator.…
Permitting a wellhead meter to read high robs your employer. The royalty and severance tax payments made by the lease operator are based on the…
If the interface level controller on the low pressure, three phase separator malfunctions, a well’s entire production of natural gasoline may wind up in an…
