DynaPump Green Solution
 Virtually
undetectable from a distance, DynaPump’s small footprint, vertically slow stroke
and reduced noise features blend well into any landscape. Superior electrical
efficiency, variable frequency drive, soft start feature, and adjustable stroke
speed allow DynaPump to operate with less consumed energy than any other comparable
artificial lift product. A long stroke and unique features significantly reduce
downhole failures resulting in far less well intervention — helping to preserve
the natural environment.
ADJUSTABLE AUTOMATIC FLOW CONTROL
The built-in electronic controller on the DynaPump includes functions, which
act as a pump-off controller, but without intermittently shutting down the unit.
As part of its standard instrumentation, the DynaPump obtains a dynamometer card
on each stroke. One of the adjustable load set points can detect when the well
is in a pumped-off condition. When a pump-off condition is detected, the unit
automatically adjusts to a slower speed. It will periodically return to it’s
original pumping speed to check whether or not there is sufficient fluid to support
the higher pumping speed.
LIGHT/PORTABLE
The DynaPump is lighter, and more portable than conventional beam units. For
example, a Model 5 is capable of 750 BFPD from 3,000 ft. deep. A C-456- 305-120
beam unit is required to produce the equivalent volume. The Model 5 wellhead
unit has an assembled weight of 5000 pounds and the power unit a weight of 600
pounds. The C-456 has a bare weight of 18,440 pounds (without counter- balance),
and with maximum counterbalance weighs 43,420 pounds.
LOWER TRANSPORTATION COST
The lower weight and compact size of the units can result in lower transportation
costs, particularly if several units are shipped simultaneously. Savings of 25%
were estimated by the operator for an application in Utah based on using a DynaPump
Model 5 rather than a C-456 beam unit.
LOWER INSTALLATION COST
The low weight, compact size and ability to ship DynaPump wellhead units fully
assembled result in reduced installation costs. The small footprint of the wellhead
unit and lack of massive rotating counterbalance weights results in less massive
foundations. The light weight requires smaller lifting equipment, reducing costs.
Since the wellhead unit is shipped fully assembled, only one lift is required
for placement. A second lift to unload the power unit completes the operation.
This reduces the time required for field installation, further reducing costs.
In one example, a reduction of greater than 40% was estimated by the operator
for foundation and crane work compared to a beam unit.
LOW INSTALLED POWER
When designed to take optimum advantage of the high polished
rod load capabilities of DynaPump units (i.e., large diameter pump, and long
stroke), DynaPump installations have significantly reduced installed horsepower
requirements compared to conventional pumping units.
LOWER POWER CONSUMPTION
An electrical power consumption survey of 8 DynaPump
wells and more than 50 beam pumped wells showed that mean power consumption of
the DynaPump’s was more than 30% less than conventional units.
