AMSTERDAM, Sept 28 (Reuters) - Dutch oil and gas company Dyas and Canada's largest energy firm PetroCanada are looking to sell their stakes in one of Europe's largest gas storage projects, three people familiar with the matter said. The two companies want to exit the scheme, located in Bergemeer north of Amsterdam, because of disagreements with partner Abu Dhabi National Energy Company (TAQA) TAQA.AD over how to take the project forward, one banking source said.

"TAQA would be the obvious buyer of their stakes, as they can develop the project from here," the source said. Pre-emption rights in such cases are often part of Dutch oil and gas agreements.

TAQA, which is to operate the facility, has a 36 percent stake in the project, while Dyas and Petro-Canada each have 12 percent. Dutch state energy project developer Energie Beheer Nederland has a 40 percent interest.

"As with many Dyas projects, we may sell but have not yet decided," a Dyas spokesman said.

Petro-Canada, now part of Suncor Energy (SU.TO), did not respond to a request for comment, while a TAQA spokesman said the firm did not wish to comment on other companies' business before they have made their official announcements.
