Sammendrag
When a company undertakes to develop an oilfield, certain activities represent the
foundation of the development, ranging from information about the metocean conditions at the
site to marketing.
The concept phase itself includes screening of concepts, selection of concept and
concept development. Use of engineering data and calculations that represents a feasibility
study of offshore oil and gas field is essentially the screening of concepts.
The selection of concept consists of finding a solution that would meet world technical,
environmental and safety demands. Despite the fact that Sakhalin Island shelf contains
enormous hydrocarbon reserves, it is also a very environmentally sensitive region. High
environmental risks and extreme weather conditions entail high capital expenditures, which
put significant burden of responsibility on the project team during the development concept
stage. This is of great importance during the early stages of concept selection.
Selecting the optimum Sakhalin Shelf development concept is the aim of my thesis.
Significance in the concept selection chain affects selection of various parameters affecting the
optimum development concept and subsequent prioritization.
Special attention is paid to challenges and peculiarities that can be faced at the Sakhalin
Region and could affect the concept of field development. My paper analysis addresses concept
screening and engineering solutions. The main driving factors of concept selection are touched
upon. The development concept and the criteria of its selection are paid special attention to in
the thesis. The criteria selection process in this case is based on scientific literature, as well as
articles and publications, containing useful material about offshore field developments in
Arctic and Sub-Arctic. Development and design industry standards, those of Russian
Federation and other countries, were also touched upon.
All analysis results are presented in the form of methodological research, applicable to
the entire Sakhalin region. A phased model for Sakhalin development concepts is created. Key
parameters are discussed for the screening stage. Comparison of criteria for concept selection
is also included.
The final model – step by step approach to concept phase execution, is concluded to be
applicable to Sakhalin oil and gas development projects.
Conclusions drawn upon provide recommendation for the concept selection, applicable
to the Sakhalin Shelf.

On a sustainable development path? A comparative case study of Norway and Sweden’s national sustainable development strategies and indicators
Optjernsberget, Hilde (Masteroppgave/UIS-SV-IMKS/2015;, Master thesis, 2015-06)This thesis explores the phenomenon of national sustainable development strategies by comparing such strategies for Norway and Sweden. Based on the operationalization of their strategies into goals and indicators, it is ... -
Rationale for Development of Design Basis for Barents Sea field developments
Gudmestad, Ove Tobias (Peer reviewed; Journal article, 2019)Developments of hydrocarbon fields in the Barents Sea would normally include surface process units; thus, we must take into account the ice conditions in the area. Alternatively, smaller fields can be developed as satellites ... -
