T This study was conducted on 11 producing wells in the pas field, consisting of five electric submersible pump (esp) wells and six hydraulic pumping unit (hpu) wells. the evaluation was performed based on reservoir efficiency and lifting efficiency to determine the condition and optimization recommendations for each well using the quadrant method. inflow performance relationship (ipr) curves were developed using the vogel method to determine the absolute open flow potential (aofp), while the optimum flow rate was defined as 80% of the aofp. reservoir efficiency was calculated as the ratio of the actual flow rate to the optimum flow rate, while lifting efficiency was calculated as the ratio of the actual flow rate to the esp pump capacity or hpu pump displacement. both efficiency values were plotted on the evaluation and optimization quadrant with a classification threshold of 70%. the evaluation results showed that wells asb-039, asb-065, asb-067, pa-439, pa-445, and pa-458 were located in quadrant i and were considered to be operating optimally. wells pa-460 and pa-473 were located in quadrant ii, well pa-450 in quadrant iii, while wells pa-385 and pa-454 were located in quadrant iv. the five suboptimal wells were subsequently modeled using pipesim, followed by a matching process. optimization of well pa-385 was performed by replacing the td-460 pump with a td-300 pump at an operating frequency of 75 hz and 103 stages, resulting in a production rate of 297.5 stb/day, with reservoir and lifting efficiencies of 95.2% and 99.2%, respectively. well pa-450 was optimized by increasing the operating frequency from 41.5 hz to 100 hz while maintaining 110 stages, resulting in a production rate of 426.4 stb/day, with reservoir and lifting efficiencies of 92.5% and 92.7%, respectively. well pa-454 was optimized by replacing the td-460 pump with a td-300 pump at an operating frequency of 80 hz and 140 stages, resulting in a production rate of 280.3 stb/day, with reservoir and lifting efficiencies of 99.6% and 93.4%, respectively. for wells pa-460 and pa-473, optimization was performed by increasing pump displacement through an increase in pumping speed from 4 to 16 spm and from 2 to 4 spm, respectively. the optimized production rates reached 921.7 stb/day and 184.7 stb/day, with reservoir efficiencies of 91.8% and 92.6% and lifting efficiencies of 97.6% and 97.8%, respectively. the results indicate that the quadrant method can be used to identify wells requiring optimization and determine appropriate optimization actions, while modeling and optimization using pipesim can increase production rates and achieve reservoir and lifting efficiencies above 70%.
