Oil & Gas Project Disputes

With deliverables management, we make the whole process of working with us easy and rewarding.

With oil and gas project management disputes, cases can drag on for months, or even years. It’s a drain on your associates to keep track of reports and other expert-relevant documentation.

We make sure everything is kept up to date, with traceable version histories. Complex cases may involve different experts over time, so we are scrupulous in coordinating our experts and their opinions to build a comprehensive view as people come on and off the case.

Through our knowledge base we can provide reports and opinions from similar cases on both sides of the dispute. We can also assist your team with research.

We also handle the logistics side of getting experts to sites around the world to undertake their investigations or give their expert testimony.

Contact us today to discuss how we can help your next case.
