“…Specialized literature exists on the criteria and key decision factors to be considered during the identification of the best host for a given offshore field development, see for example (Reid, 2013), (Dekker, 2014), or (D'Souza, 2011: this crucial decision is typically made during the Concept Selection stage of a project and is then confirmed through Pre-front end engineering design (Pre-FEED) and FEED work.…”

Subsea processing (SP) technologies and host facilities are distinct building blocks in offshore oil and gas field development; they can be regarded as complements or alternates depending on the given scenario. This paper will present a unique insight into these scenarios including applicable interactions. It will highlight the key parameters in this rarely investigated correlation which influence concept selection and full field development (FFD). The paper will also shed some light on key FFD drivers such as reservoir size and (qualitative) economics.This paper is based on thoroughly conducted secondary research covering 72 past, present, and potential-future related projects around the world. A multidisciplinary approach leveraging expertise in field development, topsides and subsea processing was developed to highlight the trends and possible future applications.The study reveals a direct correlation between subsea processing systems and host selection which plays a vital role in concept feasibility studies and full field development. Numerous subsea processing parameters have been considered during this study and a few have shown significant effects on host selection -reservoir size, water depth, field typology, etc. The generated trends reveal interesting winners and losers for various technical configurations, including a slight technology limitation dependence on geographical region. Although it may be possible to predict future applications of subsea processing technology and optimize designs based on the host's interaction with the subsea processing system, the market uncertainties still remain high; nevertheless, recommended areas of focus are presented in this paper based on identified gaps. There are not many publications on this subject; therefore some of the observations presented in this paper are novel. 2OTC-25675-MS

“…Oil and gas exploration and exploitation require a large amount of economical resources mainly in offshore environments thus, field development planning has the main objective of maximizing the revenue for a given investment, this is maximizing the utility index (UI) defined as UI = NPV/NPI, where NPV is the net present value and NPI is the net present investment value. Scenarios with the greatest median (P 50 ) NPV and lowest spread between P 10 and P 90 NPV will be selected [1]. Economical evaluation becomes complicated since for example date of initial production and price of hydrocarbons vary randomly.…”

Two methodologies to rank exploitation scenarios for hydrocarbon fields during screening and concept selection stages are described and compared. First a selection based on net present value valuation is introduced and an explanation on its limitations for field planning are given thus, a second selection based on a multiattribute decision model where other technical factors not directly associated to economics such as operability and reliability are considered. A comparison of net present value and the multiattribute decision model on a concept selection study case shows differences on the scenario selection for exploitation. Sources of the different outcomes between the two methodologies are identified. A stochastic analysis for the multiattribute decision model is performed to have a complete view of the possible outcomes since the factors in the multiattribute decision model are measured qualitatively and their values can vary depending on experts’ knowledge and experience. Recommendations obtained from the methodologies studied for screening and concept selection are given

The development of petroleum production systems has become more and more sophisticated due to the complexity of deepwater oilfields. Selection of a field development option in early phase will significantly affect overall project economics, schedule and risk. Important factors that drive the selection of a deepwater field development and production system that including subsea production, floating platform, flowline and riser system and export system are identified in this paper. The screening starts with a fair number of potential alternatives. Invalid or obviously inferior combinations were eliminated and this yields a “long list”. Considering the factors reservoir, fluid characteristic, wells, regions and so on, a “short list” was resulted. Finally, it presents a model for decision-making that takes into account the main goals of a company, through the use of fuzzy mathematics. A case study results suggest that the best alternative is not always the one existing the best economic indicators.
