Eduardo Costa, the CEO of Ouro Negro, said that the partners hoped to make the tool as autonomous as possible by incorporating TTilt technology into Wellrobot, the autono- mous modular robotic system they have already designed for well inspections. “This will reduce the need for well interventions, with their high costsandimpacts,”hesaid.“Thisisbecausethe robot [will be] permanently installed in the well, continuously analysing and passing the data on.”
Garcia agreed, saying: “The TTilt on its own would be extremely disruptive. However, its incorporation into the Wellrobot and all these other possibilities would take this disruption to a currently unimaginable, albeit perfectly
possible, level.”
Professor Arthur Braga of CTC/PUC-Rio’s
Mechanical Engineering Department, which is the leader of the academic component of the partnership, said he hoped that a tool of this type would help oil and gas operators overcome the challenges that well plugging and abandon- mentcanpresent.
“To be permanently abandoned, the well must be sealed hydraulically in order to isolate the reservoir and other fluid-bearing forma- tions, thus preventing leaks into the vicinity and potential large-scale environmental disasters,” he said. “Hence the importance of developing technologies to assess cement integrity and its sealing capacity.”

Eco Atlantic ally optimistic about prospects for additional oil finds offshore Guyana
KINLEY Exploration, a US-based company with close ties to Canada’s Eco Atlantic Oil & Gas, has expressed optimism about the pros- pects for further oil discoveries offshore Guyana.
According to Greg Embery, Kinley Explora- tion’s vice-president of geology, Eco Atlantic saw Guyana’s Orinduik block as highly prospective because of its similarities to a confirmed oil find made off the coast of Africa.
Since the two sites were closely connected before they were separated by continental drift, this raises the possibility of further analogous discoveries, he said.
“There’s a fair amount of oil there,” he told the Fox affiliate TV station in Kansas City. To date, he said, Eco Atlantic and its partners have deter- mined that Orinduik alone contains 220mn barrels of crude oil worth about $13bn. This is enough oil to fill around 14,000 Olympic-size swimming pools, he remarked.
Colin Kinley, who serves as the CEO of Kin- ley Exploration and of Eco Atlantic, pointed out that Eco Atlantic’s minority share of these reserves would prove very valuable once the
block began production. “It’s Guyana’s oil, and we get our fair share for finding it,” he said. “If we put a floating platform in there and we start pumping oil a couple of years from now, we’ll pump 120,000 barrels per day [bpd], more or less, for about a six-year period. It’s pretty significant.”
Eco Atlantic holds a 15% stake in Orinduik. The remaining equity in the block is split 10% to Qatar Petroleum, 15% to Total (France) and 60% to Tullow Oil, the UK-Irish company that is serving as operator of the project. (Qatar Petro- leum arranged to join the project earlier this summer through a farm-in deal with Total.)
Tullow revealed on August 12 that it had found oil in larger quantities than anticipated in Jethro-1, its first exploration well, which was drilled in the Jethro Lobe section of Orinduik. The company and its partners are now sinking a second well, Joe-1, at another section of the block.
Orinduik is located about 120km offshore, in water depths of 70 to 1,400 metres. It covers an area of 1,800 square km.
