Buru executive chairman Eric Streitberg confirmed there is some concern over the cement bond with the Yulleroo-4 well which would be investigated as part of normal work.

The company says that remedial work might be required before that well can be fracked, as Buru hopes to do later this year.

There were no issues with the Asgard-1 and Valhalla North-1 wells, which the company also hopes to frac, once it completes a re-bidding process.

"The same thing occurs on most wells, but once the cement bond logs are rerun that has usually healed and the well integrity is okay," Streitberg explained.

"Part of our approvals to do any fraccing in Yulleroo-4 is to confirm the cement bond."

The issue at Yulleroo-4 follows an earlier claim of gas leaking from Yulleroo-2, where it would found that a valve stem had been vandalised.

A minor gas leak was quickly repaired. The integrity of the well casing and tubing and downhole components was confirmed during the operation.

The opportunity was also taken to modify the well head configuration by removing components that could be susceptible to further deliberate damage.

Speaking at Buru's Annual General Meeting in Perth last week, Streitberg was keen to push its green credentials and social licence against some obvious protestors, up in arms over the company's plans to frac several wells later this year in the Kimberley region.

While the protesters weren't exactly out in force outside the meeting, there were still almost two dozen people decrying the company's plans, now delayed, to frac the Canning Basin.

With banners such as "invest in our future, not fraccing", the Wilderness Society-organised protest was a short-lived affair, relatively polite and hardly needing the five police offers on hand.

Inside the meeting, Streitberg outlined the company's fully funded, 5-7 well oil-chasing program planned to kick off with the Olympus-1 well later this month.

He said he was "happy" to step back into running Buru on a day to day basis as executive chairman because he had a genuine passion for the Canning Basin, which was an amazing, once-in-a-lifetime opportunity to develop Western Australian, protect the environment and benefit the three major traditional owner groups in the Kimberley.

Despite stressing how collaboratively and carefully Buru has worked with traditional owners, there was at least one person in the crowd not having a bar of it.

One traditional owner from the Yawuru claimant group, Micklo Corpus, travelled from Broome, and with WA Wilderness Society state director Jenita Enevoldsen pressed Streitberg on a statement allegedly made in 2010 that Buru would not conduct operations in the Yawuru lands.

Corpus has been conducting a one-man blockade and protest of the Yulleroo site.

"With respect, we do have a very good relationship with the Yawuru people, but obviously there are some Yawuru people who take a different review, but we continue our engagement, and will always sit down and talk," Streitberg said.

The Yawuru were the last of three groups to sign an indigenous land use agreement with Buru to allow it to begin commercial oil production at the Ungani well. As part of that process, Yawuru as well as the Nyikina-Mangala and Karajarri-Yanja groups expressed opposition to the fracking, but they have no power to enforce that veto.

Claims that 96% of the local groups were opposed to the proposed fracking program were questioned, with Streitberg stressing that Buru was "absolutely committed" to the company's environmental and community engagement programs.

"We have tried, and I think succeeded to be a very good corporate citizen, and we have been very proactive on the environment side. We exceed by some large degree the regulatory requirements for our operations," he said.

For example, he said seismic lines from 2012 had been returned to their natural state and could not be located even with GPS.

"We have changed out techniques dramatically, and we have learned. We have very extensive groundwater monitoring programs, and have shown no affect, whatsoever, from any petroleum operations. "

Long-term flora and fauna programs all involve the traditional owners, and the company has put a lot of effort engaging with the traditional owners.

He said the company recognised there some concerns about its activities, and said the company held regular community meetings to assuage concerns.

Buru has approval from the West Australian Department of Mines to frack four wells in the oil-rich Canning basin this dry season, but that approval expires in June, and it is likely to have that extended.

The meeting was more sedate that last year's to-do, where Buru earned a first strike on its remuneration report.

Streitberg said he and the board had heard the calls, and had restructured the company with lower overheads and more appropriate salary levels.

He defended last year's hefty $524,000 termination payment, a key point of contention last year, saying it was a contractual right established to recognise the comparatively low level of his salary when the company has been established.

And he said at the time he'd genuinely had no plans to step back into an executive role, but he'd been press-ganged after his replacement Dr Keiran Wulff stepped down.

And his new contract has no termination payment.

Streitberg expects to be in the dual role of chairman and managing director until at least the end of the year, at which time he hopes an expanded board is in a position to complete a natural transition to a new chairman.
