Chevron - Gendala & Gehem Field Development, Water Treatment System Review, 2013
Independent study review of the FEED design for the proposed water treatment facilities for the Gendala and Gehem developments. The study report presented an independent review of the design proposed by the selected FEED engineering contractor.
BG Group - Liquid & Gas Phase Contaminants Tool Box, 2012
A desk top study based on identifying and detailing on-line and offline analytical methods and removal technologies for the analysis and removal of certain contaminants in hydrocarbon streams. The driver behind the project was to identify where gaps exist for the analysis and removal of certain contaminants in hydrocarbon streams. Such contaminants can impact on product quality and hence price so it is important that there is capability to both analyse and remove them.
BP - Forties Pipeline System (FPS) HAZOP, 2012
Review of the BP FPS operating procedures to implement changes required following completion of a major HAZOP on the FPS pipeline system.
Nexen Buzzard - Water Treatment Package Commissioning, 2011

BP Azerbaijan - Produced Water & Sand Handling Review, 2010
This study was part of a large scope to examine produced water and sand handling practices at the BP Azeri assets in the Caspian. The BP platforms in the Caspian have major issues with sand production. The study examined current sand handling practices and how these could be modified to improve sand handling and disposal. Part of the study also focused on the management of suspended solids and how these could be minimised in the produced water to meet the required injection water specification.
Chevron - Sand Technology Review, 2008
Desk top study which reviewed commercially available sand removal and treatment technology and on-line sand detection technology.
Swift Energy - Produced Water Analysis for Lake Washington PWRI Assessment, 2008
