20040216886, Nov 4, 2004

Filed:

May 19, 2003

Appl. No.:

10/440903

Inventors:

Jack Rogers - Tyler TX, US

International Classification:

E21B043/00

US Classification:

166/372000, 166/105500

Abstract:

Method for operating a well installation utilizing a chamber in operative association with plunger lift to carry out deliquidfication. Injection gas may be employed for plunger lift in a manner wherein the injection channel is isolated from the primary annulus of the well adjacent the casing. Gas is produced through that primary annulus.

US Classification:

Abstract:

A method for producing a plunger lift well which optimizes production through the evaluation of the speed at which a plunger arrives at the wellhead within a fixed on-cycle interval. Time interval windows representing fast, good, and slow plunger performance are established and, based upon plunger performance with respect to these windows, afterflow time and off-cycle intervals are varied toward an achievement of plunger arrivals within the good window. A minimum off-time is established as a limit. The method may be employed with two motor valves, one performing in conjunction with a sales and the other to low pressure such as the atmospheric pressure of a tank or a low pressure sales line. In the event of failure of the plunger to arrive within the on-cycle interval, resort is made to the tank cycle. Additionally, an afterlow delay cycle is provided as well as a delay cycle intended for response to high sales line pressure conditions.
