Analysis of Down hole Gas Separators In Sucker Rod Pumping
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 12
Abstract
Oil exploration phase consists of prospecting, drilling, completion and production. Initially, oil can be producedby natural elevation, using the reservoir's own energy. However, the well loses energy with the time and it becomes feasible the implantation of an artificial lift method. The sucker rod pumping is the most worldwide used method in the oil industry, especially in Brazil in onshore wells. One of the problems on the operation of this method is the presence of gas at the bottom of the well. The most commonly way to avoid this problem is to use a natural gas anchor, which employs gravity and physical properties of the fluids for an effective separation. If the amount of gas produced is greater than the capacity of the separator, the separation will not occur effectively. The excess of gas will then enter the pump, reducing its volumetric efficiency and the liquid output will also be reduced. The aim of this work is to simulate gas separationin five separators with different geometries using the Total Well Management (TWM) software provided by Echometer company. It could be observed from the results that among the five different geometries, number 4, with Pdmax = 190 BPD, is the one that most closely approximates to the setted flow rate, so it would be the most appropriated one.
