Track record
Global Operations
TerraNode Tech delivers a world-class international expertise directly to your asset teams. While our consultancy operates as an agile B2B partner, our foundation is built upon more than a decade of senior-scale experience directing critical subsurface simulation and spatial big data projects for major global operators. Below is the international footprint engineered by our principals:
North Sea | Norway
Offshore Asset Optimization
Key projects
Brage, Yme, Bestla, Lunde and the Iving Field Development.
Expertise Delivered
Executed advanced analytical and numerical reservoir simulations on major mature fields and new discoveries to optimize history matching and evaluate infill well placement. This track record includes managing subsurface uncertainties for complex stacked reservoirs, maturing fast-track development concepts, and successfully designing, supervising, and evaluating high-stakes offshore well test operations—such as the 25/8-19 AT2 offshore operation—and wireline fluid acquisitions to guide critical investment decisions.
