“…This integrated asset approach ensured that the interactions among all components were correctly simulated, and the value of multiple development options or operating scenarios were compared and maximized with inclusion of economic indicators such as net present value (NPV) and investment efficiency (Perez et al 2012;Espinola et al 2014). The work presented in the next section encompasses the use of various numerical simulation software applications working together in one single simulation environment which allows logical connections, constraints and optimization routines to be implemented; sensitivity analysis on different elements of the asset and evaluation of any possible impacts among the studied elements (such as manifold choke sizing and gas lifting parameters).…”

Field development planning for an asset requires close interaction between different domains and departments, to reduce any potential uncertainties within the studied asset. Reducing uncertainties is crucial in investment preparation for a new green field development. By adopting an integrated asset approach, such cross-department interactions can be further improved by breaking down the barriers and assembling an integrated asset team with a common goal. This paper summarizes the construction of an integrated asset study for an offshore green field and compares the study against those obtained from the standalone-domain models. In this study, a reservoir simulation model was coupled to the wells and network models, which were further integrated to the processing facilities models and the asset economics evaluation model.The aim of the study was to evaluate an existing field development plan (based on the traditional standalone approach) with an integrated asset approach to identify any possible constraints and potential deviations, enabling proactive actions to be taken on the asset management for future operations. The work presented here encompasses the use of various numerical simulation software applications working together in a single simulation environment, which allowed sensitivity analysis on different elements of the asset and evaluation of any possible impacts among the studied elements, such as manifold choke sizing and gas lifting parameters.This assessment consists of a study from reservoir to economics, taking into account of wells, pipelines, surface equipment, production networks and downstream process facilities. The study demonstrated any components of the production network system and topside operating condition could impose constraints on the reservoir deliverability. Apart from evaluating various operating scenarios to best utilize the emerging capacity and to investigate back-out efforts and other challenges during the field development, it also provided guidance on how to further optimize the production system in terms of finding choke sizes over time and adjusting gas lift injection according to gas availability and operating pressure constraint. With its integrated asset approach, this study also presented a base case that could be extended with inclusion of gas lift distribution system to enable a more comprehensive analysis and asset field development study.

Reservoir to surface Integrated Asset Modeling (IAM) is a cross-functional simulation, monitoring and decision tool. It captures the complex interactions all along the production / injection system of an oil or gas development. It is a powerful tool to maximize the value of an asset from the development phase to the end of the production period. This paper describes the successful work achieved for unlocking the challenging development of Absheron deep offshore gas condensate field through an integrated asset work and modeling. The IAM has been the result of a multi-disciplinary and collaborative work where each disciplines, namely reservoir, well, network and surface process engineering, provided their inputs. A fully compositional fluid modeling was required to capture the challenges of such a long gas export production line with stringent thermal requirements due to the paraffinic content of the produced condensate, impacting at first order both plateau duration and economics. During all the pre-FEED engineering, attention was given to ensure consistency and synchronization between the IAM and the progress of the design work performed in parallel by each disciplines. Many sensitivity calculations on development parameters have been performed to quantify the impact of the geosciences uncertainties and other design parameters to define the optimum combination of production facility design, operating philosophy and monitoring strategy. The first phase has been a screening with different production network design parameters associated to the base case reservoir model, namely the pipeline insulation and the arrival pressure. The second phase has been to test the robustness of the proposed design towards reservoir base case uncertain parameters such as the well overall exchange coefficient, reservoir temperature, water break-through, fluid modeling and gas-water contact. The third phase has been to test the robustness of the proposed design towards low and high reservoir cases. All along these phases, many iterations and collaborative work between reservoir, well, network and process engineers occurred, all centered around the IAM offering the possibility to evaluate the production profiles associated to different designs assumptions while the different disciplines eventually performed more advanced "stand-alone" studies to further assess specific technical points. The work performed for Absheron development highlights the benefits of integrated asset work and modeling to enable an economic development scheme robust towards uncertainties (petrophysical, structural modeling, water break-through…) and therefore not over designed
