“…The main contributors to an integrated reservoir management are: well design and management, reservoir characterization, reservoir modeling, surface facilities design, and economics. The integration of these items enables one to propose and design efficient and economic ways of producing reservoirs, adding value to companies' assets [3].…”

Well prioritization rules on integrated production models are required for the interaction between reservoirs and restricted production systems, thus predicting the behavior of multiple reservoir sharing facilities. This study verified the impact of well management with an economic evaluation based on the distinct prioritizations by reservoir with different fluids. We described the impact of the well management method in a field development project using a consolidated methodology for production strategy optimization. We used a benchmark case based on two offshore fields, a light oil carbonate and a black-oil sandstone, with gas production constraint in the platform. The independent reservoir models were tested on three different approaches for platform production sharing: (Approach 1) fixed apportionment of platform production and injection, (Approach 2) dynamic flow-based apportionment, and (Approach 3) dynamic flow-based apportionment, including economic differences using weights for each reservoir. Approach 1 provided the intermediate NPV compared with the other approaches. On the other hand, it provided the lowest oil recovery. We observed that the exclusion of several wells in the light oil field led to a good valuation of the project, despite these wells producing a fluid with higher value. Approach 2 provided the lower NPV performance and intermediate oil recovery. We found that the well prioritization based on flow failed to capture the effects related to the different valuation of the fluids produced by the two reservoirs. Approach 3, which handled the type of fluids similarly to Approach 1, provided a greater NPV and oil recovery than the other approaches. The weight for each reservoir applied to well prioritization better captured the gains related to different valuation of the fluids produced by the two reservoirs. Dynamic prioritization with weights performed better results than fixed apportionment to shared platform capacities. We obtained different improvements in the project development optimization due to the anticipation of financial returns and CAPEX changes, due mainly from adequate well apportionment by different management algorithm. Well management algorithms implemented in traditional simulators are not developed to prioritize different reservoir wells separately, especially if there are different economic conditions exemplified here by a different valuation of produced fluids. This valuation should be taken into account in the short term optimization for wells.

Sound reservoir management practice aims to maximize economic recovery while smartly reducing capital investments and operational costs, optimizing the utilization of technology and talent. Nevertheless, such a conceptual approach, seemingly linear and focused, is challenging in large corporations, for the numerous reservoirs that are produced at different stages of maturity, by a variety of teams. This is the case of Kuwait Oil Company, the main oil operator of the upstream sector in the State of Kuwait. After more than 67 years of commercial oil production, the company has evolved into a large and complex organization composed by assets and support groups. Incrementally, the need of standard practices of Reservoir Management (RM) is evident, to maximize the optimization efforts at corporate scale. As an unprecedented initiative, Kuwait Oil Company (KOC) engaged in a journey of standardization of its RM practices, to manage with top standards its more than 142 oil and gas fields on the inland territory of Kuwait. The initiative comprises a two-fold effort: A formal project led by KOC's RM Team, to identify and assess the status of RM Practices in KOC;A Steering Committee of executive level, charged with the implementation of standards policies, guidelines, and workflows for RM. All Assets in KOC are already benefitting from this approach, as the initial results from the assessment of the current status of Reservoir Management Practices, have established the good practices, as well as the tools and techniques to be massified. At the same time, the identification of existing gaps in Reservoir Management Practices was completed, establishing a clear plan to minimize them. The acceleration of the uplifting of KOC's Reservoir Management (RM) processes, will need a sound governance model for the implementation of the RM policies, grounded on the findings established and customized to the corporate organization and goals of KOC. The achievement of short- and mid-term goals has started, with the PIP (Process Implementation Projects), aimed to enable important improvements of RM in all oil and gas Assets of KOC.
