Even before the first drops flow, Uganda's oil sector is beset by bribery allegations against officials, tax-related cases abroad that cost the government millions in legal fees, and the alleged interference of a president whose firm control of the sector worries transparency campaigners.

Uganda, which has confirmed oil deposits of about 3.5 billion barrels, wants to extract at least 1.2 billion barrels over the next three decades. That figure could rise when more oil blocks are put up for exploration later this year, potentially making Uganda one of Africa's top oil producers.

But some experts and analysts worry that the country got off to a false start and remains too politically unstable to avoid some of the mistakes made by other oil-rich but otherwise poor countries.
