Gas lift optimization and design has traditionally used single-string analysis to perform optimization. This required time consuming exercises and lengthy processes that never achieved the global reach of field constraints management. In a dynamic brown field where field interruptions and process upsets are common, response time is a key performance indicator. These challenges were effectively overcame by introducing a Real Time Production Surveillance and Optimization system capable to perform dual string gas lift optimization field-wide and in real-time. The implementation was the first Real Time Production Surveillance and Optimization system in the country. The system links up real-time operational data historian system and corporate production information management system (PIMS) and is coupled with the Well-Network suite of simulation tools to provide an integrated suite of production surveillance, diagnostic and optimization application modules that increase the efficiency of daily oil and gas operations activities. The goal of this paper is to underscore the advantages and benefits that can be drawn from the utilization of Real Time Production Surveillance and Optimization System during the operational phase of production optimization process.

AbstractIn general, mature oilfields have a good portion of the remaining reserves still trapped due to inefficient drainage, production decline, increase in water cut and sand production and aging of the existing systems. This paper addresses techniques and initiatives to optimize development plans in a mature field. For Bokor Field in particular, there have been identified and implemented opportunities such as Infill drilling and workover optimization, dynamic underbalance perforation (DUP), matrix acidizing and propellant stimulation, water shut-off mechanical (WSOM), sand management, through tubing stand alone screens, deployment of electrical submersible pumps (ESP) and gas lift NOVA valves, real time surveillance (DHG, DTS and LiftWatchers*) and optimization, and microbial EOR.Before the implementation of these techniques, this field had a daily oil production equivalent to 10 MSTBD (after fields decline) and the current production is 26 MSTBD. The two main reason for this increase are:• New technologies were employed in this oil field with dramatic results incorporating new hydrocarbon reserves, via 3D seismic techniques, high resolution stratigraphy and better static and dynamic simulation models. • Multidisciplinary integrated studies to increase field ultimate recovery factors by improvements in drilling, workover, stimulations, facilities and EOR methods.
