Brazil: Repsol Sinopec Brazil, Ouro Negro and the Mechanical Engineering Department of the Centre of Science and Technology at Rio de Janiero’s Pontifical Catholic University (PUC-Rio) are working together on a through tubing logging profile tool to assess cement quality in lined wells. Arbolas has reported that, where current technologies allow only for observation of anomalies located directly around the tool, the sought-after solution will facilitate detailed recording of the integrity of the adjacent layer. Ouro Negro Chief Executive Officer (CEO) Eduardo Costa has described the proposal to incorporate its TTilt technology into the Wellrobot, yielding continuous data feedback and thus reducing well interventions. The companies say that the prospect of reliable seal integrity testing for plugging and abandonment operations on fluid-bearing formations is of enormous economic and environmental import to numerous industries.
