Multi-Stage Limited-Entry Gas Separator - Limited-Entry Explained and Test and Results

A new gas separation technology was released last year with the goal of creating a substantially increased volume capacity and therefore significantly improved separation quality through application of a process known as limited-entry.  This process is more commonly applied to well fracturing and other stimulation procedures wherein the principle is applied to create an equal distribution of fluids to be pumped into an expansive length of producing formation.  

This paper will explain the process of limited-entry as it applies to gas separation design and how the resultant MSLE separator functions differ in regards to other commonly applied separators.  Further, a notable series of MSLE separator tests will be reviewed to illustrate lessons learned, design improvements implemented, and overall performance achieved in a variety of well conditions.
