Halliburton and Brazil’s Petrobras entered a multiyear agreement to facilitate solutions for geophysics, drilling and completions, reservoir characterization, well testing, flow assurance and production in deepwater presalt areas, mature fields and other complex reservoirs, according to a January press release.

The companies aim to reduce well construction investment, focus on long-term reservoir monitoring and increase well productivity.

This multiyear collaboration is the second phase of a technology collaboration between the companies in Brazil, the company said, noting that during the first phase—which began in 2009—they collaborated on 11 projects including prestack seismic attributes for carbonates, new algorithms for better estimation of fluid sampling contamination, and a new cementing system for salt and CO2 environments.

Halliburton’s Brazil Technology Center in Rio de Janeiro is being used in the project. It is one of 15 global centers for technology, Halliburton said.
