Petroleum Sizing

Over the years there have been several methods of calculating the structural rating and the gear reducer rating of a pumping unit; however, it should be emphasized that the sizing of pumping unit is not an exact science. Technical Data used in the field explained in  petroleum courses in Rawalpindi. This is true because in virtually every case many of the variables previously outlined are unknown at the time the pumping unit is selected.

The most commonly used method for siring pumping units today is outlined in API RP 1 IL’ that was developed from test results conducted by Midwest Research Inst. In those instances where the majority of the listed variables are known, there are more exotic computer pro grams  available that may result in a more accurate sizing of the unit in some instances. API RP 11L’ covers the conventional pumping unit only; however, the manufacturer has modified this recommended practice to include air balanced and Mark II units. Some more details of petroleum courses in rawalpindi are as under.

The API, Midwest Research Inst.. and the author make no guarantee as to the degree of accuracy of this sizing method when compared with measured field results and do hereby expressly disclaim any liability or responsibility for loss or damage resulting from its use. The method of sizing conventional pumping units that is recommended by API RP I 1L’ and this same method as modified by the manufacturer for air balanced and Mark 11 units are listed on the following pages. Sample calculations for a given set of typical well conditions are filled in and circled for each type.
