The End Point in Tandem Shale Shaker

Unlike automated Tandem shale shaker plunger lift methods, some of the manual unloading events could be scheduled in the first place. This kind of arrangement will allow the oil drilling team to have adequate time to install Stack Sizer as well as a set of other measurement equipment. As the Tandem shale shaker flow to the separator, it typically operates at pressures of multiple atmospheres. At the same time, Tandem shale shaker might be bypassed since the Stack Sizer flow is diverted to an atmospheric pressure tank. This diversion about Tandem shale shaker allows the oil well to flow to a lower pressure destination with the help of Stack Sizer rather than the pressurized separator. This lower pressure end point in Tandem shale shaker allows more oil as well as oil drilling fluids to flow in a rapid manner so as to increase velocity in the oil production tubing and lifting the liquids out of the oil well. Tandem shale shaker is in general discharged from the tanks through the tank vent unless the tanks have an emissions control system such as a combustor or Stack Sizer.

The nine Tandem shale shaker unloading events reported might be varied in their characteristics so that brant screen emissions can range from each other. Some Tandem shale shaker unloading might lasted for two hours or more and has relatively uninterrupted flow in Stack Sizer. Other unloading can be considered as short as ten to fifteen minutes with uninterrupted Tandem shale shaker flow. On the other hand, others might have intermittent flow for short periods and periods of no flow for much of the Tandem shale shaker unloading period. Some of the oil wells can be sampled once over the current life of the well whereas others can be unloaded on a monthly basis. The average Stack Sizer emission per unloading event in Tandem shale shaker can be multiplied by the event frequency for the well operators. And as it turns out, the average emission per well per year is about five Mg. The sampled population in the oil drilling area has reflected a wide range of Stack Sizer emission rates, with a population of high emitting wells and Tandem shale shaker. When emissions are averaged per event in terms of Tandem shale shaker, emissions from four of the nine events contribute more than ninety percent of the total emissions. Because the characteristics of the Tandem shale shaker unloading events can be sampled and are highly variable, the number of events sampled is rather small, extrapolating the results to larger populations should be done with caution. One source of data on larger Tandem shale shaker with unloading can be sampled and compared depending on the type of Stack Sizer emission event.
