"As a result of your support we were able to plan and safely execute a deepwater drilling program on time and on budget, despite a major loss circulation event in the first well. Without the experience and professionalism of Exceed, we would not have been able to complete our drilling program."

President, Independent Operator

"Exceed Performance Improvement is best in class, always raising the bar, involved, dedicated and knowledgeable. The iVISION videos are excellent and we relied heavily on Exceed’s planning readiness to capture the learning."

Operator, West Africa

"The safety support was beneficial, while the planning and learning meetings were very helpful to the team and operations. Videos and incentives were great morale and team builders. You really brought the 3rd party guys into the team too. You are best in class!"

Operator, West Africa

"APMs are key and do a great job keeping the team focused. The videos help everyone and team AARs make a big difference. Tullow cannot operate without the service you provide - these things just would not happen."

Completions Engineer, West Africa

"Exceed planning, tracking, and incentives were very good, meetings were well run, learning was constant. EHS support was great, all initiatives had safety focus. The videos are great for morale, learning and communication. They really helped the onshore team understand what was going on when we had issues or lessons learned to follow up."
