... of k=0.20 W⁄mK and considering r 1 =4.5 inch and r 2 =8 inch (4 inch of thermal insulation), a global heat exchange coefficient U=1.45 W⁄m²K is obtained, justifying the origin of the value used in this study. For all the scalable scenarios studied, the flow regime in the horizontal flowline...

... provided by gas turbines by wind energy, thus contributing to the decarbonization of offshore O&G production. The water injection scenario was defined by Petrobras and includes subsea pumps with power distribution and control system placed on- board the FOWT. The FOWT substructure and its mooring...

... evaluating a kick scenario and shortens the time frame reaction to deal with an inconclusive pressure/flow check. The novelty is the usage of a drilling digital twin to include a false kick analysis, enabling it to detect whether just a thermal effect occurred instead of a real kick. The numerical simulation...

... campaign on this complex scenario. Once created a 4D GM model, a general methodology to predict WBS consists of directly extracting interval velocity, stress tensor, pore pressure and elastic properties from the model to the new survey and calculate rock mechanical properties and mud window...

Each brazilian scenario offers physicochemical particularities due to the inherent well characteristics, which are based both on the matrix...

.... The value of each parameter was calibrated based on existing published literature, and they were varied from maximum to minimum values against a base case scenario. The sensitivity analysis demonstrated that well spacing was the most significant parameter affecting the amount of geothermal energy production...

..., the design of a carbon-neutral offshore production system (assumed a FPSO unit - Floating, Production, Storage and Offloading ) requires added infrastructure to capture, compress, transport and reinject CO2 from third party sources. On this scenario, onshore dry CO2 sources shall be connected to the FPSO...
