Samarang Integrated Operations (IO) - Reusability and Repeatability Process for Scaling up to Multiple Assets Implementation
Samarang is an oil field located offshore Sabah, Malaysia. The field was developed in 1975 and comprises wellhead, production and gas compression platforms, as well as personnel living quarters. The majority of the platforms have fully pneumatic instrumentation / control and shutdown systems, with no provision for remote monitoring/control. The field is undergoing a major redevelopment project that consists of two phases: Phase 1: revisit two drilling platforms with the scope of drilling five new dual completion wells from SMDP-B and SMJT-F platforms.Phase 2: implement EOR phase, GASWAG (Gravity Assisted Simultaneous Water And Gas injection) in two of the three main reservoirs as well as waterflood in the third reservoir and reactivate existing wells. As part of the redevelopment plan, Samarang was the first field selected for an end-to-end asset management Integrated Operations (IO) project. Its implementation deliver objective and focus at the whole of the asset operation optimization through increased level of monitoring and surveillance, diagnosis, optimization and operations transformation in a way that fits PETRONAS Carigali Sdn Bhd (PCSB) current IO state as well as future expansion plans. The IO program aims to help Samarang to address growth, organization and environmental challenges by integrating new transformational technologies with streamlined work processes, enabling: an effective working environmentstreamlined and automated work processesthe availability & accessibility of quality information across the organizationcollaboration of expertise across multiple locations, teams and domainsintelligent alarms and alerts for continuous asset awarenessan increased in hydrocarbon production and recovery. Since commissioning of the project, we have reported the lesson learned and early benefits in various SPE conferences. A summary of reported benefits are as follows An innovative parallel design process was invented to improve the efficiency and integrity of the design processAn IO model was described and defined for framing, planning, design and execution of the projectHeightened monitoring and surveillance through installation and retrofitting of measurements and control devices, telemetry and telecommunication infrastructure, HMI (human-machine-interface) and surveillance systemIntroduction of “Functional Base with Asset Mindset” collaborative working environment across multiple locations, team and domainsTotal asset optimization hybrid of steady-state and transient-state flow simulation technologiesQuality and efficiency improvement in terms of decision making cycle from months to a dailyWork efficiency improvement by more than 80% of staff time savingConsistent value creation with production impact more than 10,000 bopd since Phase I commissioning Being the first field selected for IO implementation means that best practices, lessons learned; processes and procedures, frameworks and operating philosophy garnered during this IO implementation will serve as invaluable references for IO implementation in other assets. This paper describes the reusability and repeatability of the Samarang IO process and its procedures, the inventorization of deliverables and how these could be leveraged and scaled up for application to other assets (or a larger scale implementation).

This paper aims to describe the overall EOR GASWAG concept with some of the key findings after first phase execution and some of the measures taken to maintain the project within the planned OPEX to remain economic. Secondly, to describe a comprehensive reservoir management plan which includes a fit for purpose data acquisition plan and more importantly how the remaining challenges are addressed through the RMP optimization to maximize recovery. Finally, this paper outlines the main key challenges to be faced once the injection phase kicks off, highlighting the surveillance and monitoring strategies to overcome them.
A Simulation coupling method for surface production system optimization is developed as part of an integrated operations (IO) project that aims to support the field rejuvenation program for a mature field. The objective is to unlock surface constraints and optimize field production via a production network-to-process facility coupling method. This method allows cross-discipline engineers to collaborate and perform comprehensive well deliverability assessment, evaluate network back-pressure and various facility constraints. Such collaboration also promotes the efficiency of optimization process. The well-pipeline production network and surface facility simulation models are coupled within a single application in which the hydraulic and thermal streams are tied for modeling consistency. These are configured at the upstream end of the separator system where common boundaries are solved sequentially. A "loop-back" approach is applied to impose facility constraints to the network and the well performance will be assessed based on its response to the system back-pressure and constraints. The coupled model is optimized by a neural-network solver where constraints are set up based on operation requirement such as flaring limit, process limits, gas lift requirement, erosional velocity limit, etc. Thorough analysis can be performed by incorporating and understanding the interactions between parameters and variables of the production system starting from the well, and progressing to the pipeline network, and to the processing facility. This allows personnel from multiple domains to collaborate and achieve the following: Restrategizing the separator pressure system to meet the production target while embarking on the vision of operating with zero gas flaring. The sensitivities of production network potential against surface capacity can be performed to identify the potential optimized operating setpoints.Reducing production deferment during prolonged operation equipment upset (i.e., when pump, compressor, or separator are shut down for maintenance). The deferment can be minimized by re-routing of production and/or re-allocating the gas lift distribution based on availability.Anticipating potential operational interruptions if operating setpoints of the production network and/or facility system are changed. These changes can be due to operational requirement or production enhancement initiatives. The coupling method provides critical insights to uncover opportunities of optimizing field production and minimizing production upset and interruption. The integrated operation improves the optimization process by promoting the collaboration of multiple domains. The outcome of the coupling method should be used as basis for further transient analysis check prior to field implementation, which is an additional key facet to its technical viability in terms of operational safety and avoidance to potential risk of production interruption.
