Research Scientist
942 44 119

SP8 will develop new and improve existing technologies for subsea, in well and topside processing with minimal energy use in old and new NCS fields and support industrial technology uptake.

Objectives:

  1. Develop optimized design, models and selection methods of energy efficient subsea and in-well components (e.g. subsea, boosting) including effects of multiphase flow through complex geometries.
  2. Assess energy use of artificial lift systems and establish guidelines for field development strategies.
  3. Quantify the energy reduction potential in offshore production plants by use of energy recovery devices used in other process industries and enable technology transfer for deployment

This SP develops new, and improves existing technologies for subsea, in well and topside processing with minimal energy use in old and new fields on the Norwegian Continental Shelf and support industrial technology uptake.

Main objective

The main objective of SP8 is to optimize use of and develop new technologies for subsea, in-well and topside processing with minimal energy consumption in brownfields and greenfields on the NCS and supports industrial uptake of the innovations. This will be achieved by:

  • Demonstrating energy wastage and identifying the potential for efficiency improvements
  • Testing new technologies and concepts and by this accelerate implementation of such (green- fields)
  • Demonstrate "non-intrusive" process optimization solutions for existing fields (brownfields)
  • Study measures necessary for overcoming challenges arising from future energy supply solutions (e.g. unsteady energy supply, little excess heat)

Main results

  • The scope of work and working approach for SP8 was defined.
  • Topics to be studied were collected. The topics range from single component/technology level to complete production strategies that might be evaluated.
  • The process simulator K-Spice (by Kongsberg) was taken into use as modelling tool.
  • A PhD candidate was selected and is about to start soon. The PhD will be part of Task 8.1 "Subsea and well technologies" and mainly focus on optimization of production processes. An educational plan was prepared.

Impact and innovations

Expected innovations are:

  • Guidelines and selection help for new design and improvements of existing production systems
  • Example studies comparing and showing the potential of new technologies will simplify and accelerate implementation of such solutions
  • Boundary conditions as input to other process parts (SPs) like reservoir or energy production systems.
  • Solutions for overcoming problems related to implementation of new energy supply solutions
