Holistic modelling approach offers benefits to old and new wells 

 Our experience with subsea dynamic loading, down hole tubular assessment and extensive background in fracture mechanics combine to offer a unique well engineering capability, modelling combined loads from the vessel, environment and the well itself. Using finite element analysis, we can zoom in on tubular sections and specific components of the well. When applied to full life cycle modelling, this extremely accurate approach allows us to develop the most cost-effective well designs and aids decision-making on the operation of existing wells. 

For well abandonment projects, we collaborate with sister company Claxton to combine virtual and physical aspects to create the best real-life solutions.
