Constructed steady state and life of field models to investigate tieback options for the Caledonia field.  Analysed different production enhancement options including subsurface ESPs, gaslift injection and subsea multiphase boosting.  Performed parametric transient simulation studies to evaluate slugging and cooldown behaviour.

Peer Review of previous flow assurance studies, leading to the development of an integrated reservoir life of field model.  This model was used to evaluate the effect of backout of existing wells, and hydrate inhibitor injection requirements.

Gaz de France – Anglia NW Tieback, UKCS

A study to evaluate the sensitivity of life of field predictions to the well completion assumptions, including producing length, permeability and skin factor.  The analysis also included an analysis of refined hydrate inhibitor injection requirements taking account of pressure evolution through field life.  Simulations were performed with a third-party simulator and Maximus.

Performed parametric transient studies of various tieback alternatives for the Chestnut field in order to examine cooldown and stability behaviour.

PetroCanada – Guillemot West Extension, UKCS

Flow assurance services to the Veba WEP team, concentrating on the production chemistry implications of bringing a higher CO2 fluid into a carbon steel production system.

Provided flow assurance support to Saipem’s subsea design team, based in Fano Italy, across a range of projects, including a deepwater project in the Gulf of Mexico.

Applied Maximus to model BP/SINTEF’s novel Cold Flow process.  This included the simultaneous modelling and simulation of up to seven coexistent phases in the pipeline transportation system, including gas, oil1, oil2, water, hydrate I, hydrate II and ice.  The simulations were performed to optimise tubing/pipeline sizes, subsea multiphase boosting requirements and subsea free water separation.
