Nitrogen lifting is a common technique used to initiate production on a well following workover or overbalanced completion. A coiled tubing string is generally used to apply the treatment, which involves running to depth while pumping high-pressure nitrogen gas.
Nitrogen purging is an industry standard technique for the replacement of a hazardous or undesirable atmosphere with an inert dry atmosphere. The two most common methods of purging are displacement and dilution. The geometry of the process system determines which method is used.
Pumping fluids or sometimes slurries, by mechanical truck mounted pumps can be classified into three major groups according to the method use to move the fluid: direct lift, displacement, and gravity pumps. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system.

The fluid pump is one of most vital pieces of equipment on location. No matter how complicated a piece of equipment is, remember there is always an in and an out. To the right is a cutaway of a fluid pump head that we will take a more in-depth look at.
From the bottom, this is called the suction side. This is where fluid is coming from the 400 bbls tank being pressured by the c-pump (centrifugal pump) or mission pump. When the power end rolls over, it moves the plunger to the left which lifts the valve up on the bottom filling the middle chamber with fluid. The power end will roll over closing the bottom valve and pushing up the top valve into the discharge side of the iron. There are a lot of things when deciding which fluid pump to go with. Stroke length, surface area of the plunger, all these factors will determine how fast we can pump vs. pressure. Always stay clear during pumping operations.
