Some examples of our work

  • Due diligence

    With our extensive working knowledge of all the major producing areas and infrastructure in the UKCS we work extensively with oil companies, financial houses and legal teams to prepare or review datarooms. As well as ensuring clients fully understand the commercial framework of an asset we indentify the risks and opportunities that can have a major influence on the asset value.

  • Expert witness

    Sigma regularly provides expert witness services during dispute resolution processes and Court proceedings. Leveraging our 450 man-years of experience we offer unparalleled depth of knowledge and support for clients, using industry-renowned consultants to provide expert opinion on our multiple areas of expertise.

  • Maximising Economic Recovery

    We employ a collaborative approach to maximise economic value, using integrative negotiation tactics to optimise our client's position within a win-win outcome for the venture. We use best practice including adherence to the Commercial Code of Practice and the Infrastructure Code of Practice.

  • Hub strategy

    We are working with a number of clients to update the commercial framework for producing hubs. This can lead to novel and flexible commercial arrangements that optimise the economics for both host and users derisking the remaining field life of the assets. This not only fulfils the obligations of MER(UK) but can give owners the comfort they need to invest in the assets to defer COP and maximise economic recovery.

  • Late field life optimisation

    In a maturing UKCS we are the leading experts in opimising the remaining field life of your asset in full accordance with MER. We also help prepare for your COP decision and work hand-in-hand with the project team for a smooth decommissioning project. We are the most experienced consultancy for negotiating and working with security arrangements.
