“I’ve had the pleasure of working closely with Serkan since 2018, starting with full five-day in-house support (before the home office era) and continuing through numerous workshops, trainings, and remote sessions over the years. His deep technical expertise and straightforward, solution-oriented approach have been invaluable – he quickly identifies the root of any issue and adapts effortlessly to different colleagues and communication styles.
Thanks to his support, we were able to implement advanced features in our models, such as wettability-altering surfactants in gas-condensate systems, and build our first fully integrated surface and subsurface network models. Most recently, Serkan ran a workshop at our Hamburg office, where he demonstrated the wide-ranging capabilities of the Model Designer – something we were able to immediately apply to our current well planning and drilling activities.
Serkan is always approachable, even outside regular hours, and consistently reliable. His contribution has been key in unlocking the full potential of the tNavigator software for our workflows, enabling faster, more comprehensive decision-making across our teams in Harbour Energy.”
