Benefits of Slow-Speed Pumping
by: Paul Bommer, David Shrauner — Added 9/20/2009 12:00:00 AMSWPSC - Beam Pump Practices


This paper presents the practical and the theoretical benefits of running a sucker rod - beam lift system as slowly as possible. The slowest speed possible is defined as the speed required to pump all the liquid the reservoir will flow into the well on a continuous basis. Operational changes to create any desired speed are shown and several field examples are used to illustrate the point. The potential savings using these methods are a greatly expanded run time, the system does the minimum amount of work and requires the minimum amount of power, the reservoir is allowed to produce at maximum rates with a minimum of down time for repairs to the rods, tubing, and pump.

Improving Rod Pumping Operations in a Mature Field: A Case Study
by: Gabor Takacs — Added 9/20/2009 12:00:00 AMSWPSC - Beam Pump Practices


For maximum profits in rod pumping operations the efficiency of the pumping system must be maximized, this can only be achieved by finding the optimum pumping mode for the required liquid production rate. These principles are used in the paper by presenting a case study on improving rod pumping operations.
The project reported was conducted in a mature onshore field with 70-plus rod pumped wells. An extensive measurement program involving more than 50% of the wells was set up and pumping parameters were measured with a portable computerized system. The detailed evaluation of measurement data facilitated the detection of general and specific problems. With the aim of improving the field-wide profitability of pumping operations, an optimization of each well’s pumping parameters was made. Calculation results showed that a field-wide power saving of about 17% can be anticipated if all wells operate at their most economic pumping modes.

The profitability of rod pumping operations is a direct function of the energy requirements of pumping. For maximum profits the efficiency of the pumping system must be maximized, this can only be achieved by finding the optimum pumping mode for the required liquid production rate. These principles are used in the paper by presenting a case study on improving rod pumping operations.
The project reported was conducted in a mature onshore field with 70-plus rod pumped wells. An extensive measurement program involving more than 50% of the wells was set up and pumping parameters were measured with a portable computerized system. The detailed evaluation of measurement data facilitated the detection of general and specific problems in the design and operation of the pumping installations. With the aim of improving the field-wide profitability of pumping operations, an optimization of each well’s pumping parameters was made. Calculation results showed that a field-wide power saving of about
