Optimizing Swabbing of Marginal Wells Through Simulation Studies SPE 69515 - Dallas, Texas Society of Petroleum Engineers 2001 - Alfaro Pérez, Anthony .
Oil production through swabbing is an alternative method that becomes attractive when the production from a well is under the economic limit of any conventional system of extraction. This operation consists of running a plunger with rubber cups into the well, submerge it in the existing liquid and pulling it up, repeating the procedure until drying the well or until it is economically profitable for the service company. After some days to restore the of fluid level the procedure is repeated. The main objective of this work is to define the optimum frequency of intervention to maximize cumulative production (it is different to the maximum volume), thus resulting in maximize value. The study allows to obtain sensibility analysis to important parameters as: ; Optimum extraction of annual cumulative volume ; Optimum frequency of intervention ; Minimum levels of fluid that should be found in the wells ; Cost of each swabbing run ; Optimum annual expenses ; Maximum annual income
